BACKGROUND: Malnutrition is associated with high rates of complication, longer hospital stays, and increased morbidity and mortality. Malnutrition defined as undernutrition is common in patients with acquired brain injury (ABI); however, estimates vary remarkably. This study aimed to describe malnutrition at admission and after 4 weeks of subacute inpatient neurorehabilitation in patients with ABI using the new global consensus definition of malnutrition. METHODS: One hundred thirty-three patients with moderate to severe ABI consecutively admitted to a specialized neurorehabilitation hospital within a period of 4 months were screened for inclusion, of which 92 were included. Malnutrition was defined as at least 1 phenotypic criterion (weight loss, low body mass index, low muscle mass) and at least 1 etiologic criterion (reduced food intake, inflammation). Malnutrition on admission and after 4 weeks was compared using the McNemar test.RESULTS: The proportion of patients with malnutrition at admission was 42%, with more men (46%) than women (36%) fulfilling the criteria for malnutrition. The most frequent phenotypic and etiologic criteria were weight loss (56%) and inflammation (74%), respectively. During the 4 weeks of rehabilitation, the proportion of male patients fulfilling the individual criteria "weight loss" (difference, -21.4%) and "inflammation" (difference, -18.9%) decreased significantly; "low muscle mass" decreased borderline significant (difference, -8.9%), whereas "low body mass index" did not change. The proportion of female patients fulfilling individual criteria for malnutrition was stable or increased nonsignificantly. CONCLUSION: Malnutrition was common at admission to neurorehabilitation in patients with moderate to severe ABI, with more men than women fulfilling the criteria for malnutrition. The nutritional status improved after 4 weeks of rehabilitation in male patients, whereas it was largely unchanged in female patients. The results provide the basis for monitoring high-quality nutritional nursing care.

Aims: This study investigated the feasibility and potential effect of SCARF (Survivors of Cardiac ARest focused on Fatigue) a multidisciplinary residential rehabilitation intervention focused on fatigue and the secondary psychological and physical consequences of cardiac arrest (CA). Methods: This was a prospective one-armed feasibility study. Six progression criteria were identified related to the feasibility of the intervention and viability of a future effect study in terms of: participant recruitment (1), participant retention (2,3,4), and completeness of outcomes (5,6). Data on participant/clinician satisfaction with the intervention was also collected along with self-reported outcomes: fatigue, quality of life, anxiety, depression, function and disability, and physical activity (at baseline, 12 weeks and 6 months) and physical capacity (baseline and 12 weeks). Results: Four progression criteria were met including retention (87.5%) and completion of baseline outcomes (97.5%). Two criteria were not met: recruitment rate was 2.9 participants per month (estimated rate needed 6.1) and completion of final outcomes was 65% (estimated proportion needed 75%). Participant/clinician satisfaction with the intervention was high. Three months after the SCARF intervention small to moderate effect size changes of r = 0.18–0.46 were found for self-reported fatigue, quality of life, anxiety, depression, function and disability and for two of the physical capacity tests (d = 0.46–0.52). Conclusion: SCARF was found to be a feasible intervention with high participant/clinician satisfaction, high participant retention and the possible potential to improve self-reported and physical capacity outcomes. Procedures for study recruitment and collection of final outcomes should be modified before a fully powered randomised controlled trial is conducted.

BACKGROUND: There is little knowledge about rest-activity cycles (RAC) in patients with severe-acquired brain injury (sABI) during early in-hospital rehabilitation. This study aimed to investigate if patients with sABI displayed unconsolidated RACs at the beginning of in-hospital rehabilitation, and how these changed over time.METHODS: This study was a prospective observational study. All patients consecutively admitted to one ward were screened for eligibility. We recorded accelerometric activity for 20 days. The Daytime Activity Ratio (DAR) of activity between daytime (7-22) and the total activity during the entire day was calculated and used to estimate consolidation.RESULTS: Fifty-five patients were screened and 20 patients were included. Complete day 1 & 2 data was obtained on 18 patients. Fifty-six percentage of these had a consolidated RAC at the beginning of rehabilitation. On day 19 & 20, complete data could be obtained from 15 patients, 80% of these had consolidation of RAC. When comparing these a significant mean increase of 5.8% 95%CI(0.52; 11.01) in DAR was found p < .05, and the model of all data also showed a significant increase in median DAR over time p < .01.CONCLUSION: RAC consolidation improves over time in patients admitted for in-hospital early neurorehabilitation.

Background Persistent post-concussion symptoms (PCS) are associated with prolonged disability, reduced health-related quality of life and reduced workability. At present, no strong evidence for treatments for people with persistent PCS exists. Our research group developed a novel intervention, “Get going After concussIoN (GAIN)”, that incorporates multiple evidence-based strategies including prescribed exercise, cognitive behavioural therapy, and gradual return to activity advice. In a previous randomised trial, GAIN provided in a hospital setting was effective in reducing symptoms in 15–30-year-olds with PCS 2–6 months post-injury. In the current study, we describe the protocol for a trial designed to test the effectiveness of GAIN in a larger municipality setting. Additionally, we test the intervention within a broader age group and evaluate a broader range of outcomes. The primary hypothesis is that participants allocated to enhanced usual care plus GAIN report a higher reduction in PCS 3 months post-intervention compared to participants allocated to enhanced usual care only. Methods The study is a stepped-wedge cluster-randomised trial with five clusters. The 8-week interdisciplinary GAIN program will be rolled out to clusters in 3-month intervals. Power calculation yield at least 180 participants to be enrolled. Primary outcome is mean change in PCS measured by the Rivermead Post-Concussion Symptoms Questionnaire from enrolment to 3 months after end of treatment. Secondary outcomes include participation in and satisfaction with everyday activities, labour market attachment and other behavioural measures. Self-reported outcomes are measured at baseline, by end of treatment and at 3, 6, and 18 months after end of treatment. Registry-based outcomes are measured up to 36 months after concussion. Discussion The trial will provide important information concerning the effectiveness of the GAIN intervention in a municipality setting. Furthermore, it will provide knowledge of possible barriers and facilitators that may be relevant for future implementation of GAIN in different settings. Trial registration The current GAIN trial is registered in ClinicalTrials.gov (study identifier: NCT04798885) on 20 October 2020.

AIM: To develop and validate a prediction model for disability among young patients with acquired brain injury (ABI) after the acute phase.METHODS: Within a nationwide cohort of 446 15-30-year-old ABI-patients, we predicted disability in terms of Glasgow Outcome Scale - Extended (GOS-E) RESULTS: Baseline assessment took place a median of 12 months post-ABI. Low GOS-E (range 1-8 (best)) and Functional Independence Measure (range 18-126 (best)) along with high mental fatigue (range 4-20 (worst)) predicted disability. The model showed high validity and performance with an area under the curve of 0.82 (95% confidence interval (CI) 0.77, 0.87) in the cross-validation and 0.81 (95% CI 0.73, 0.88) in the geographical validation.CONCLUSION: We developed and validated a parsimonious model which effectively predicted disability. The model may be useful to guide decision-making in outpatient neurorehabilitation clinics treating young patients with ABI.

Made available in DSpace on 2021-06-25T10:24:37Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01 Purpose: To evaluate changes in oral health-related quality of life (OHRQoL) and associated factors in individuals with acquired brain injury (ABI) during hospitalization. Methods: Forty-six individuals with ABI were examined at week 1 and 5 of hospitalization. OHRQoL was recorded through Oral Health Impact Profile-14 (OHIP-14), clinical oral examinations were conducted, while orofacial health-related ‘motor’ and ‘cognitive’ scores were retrieved from patients’ e-journal. Association between variables were investigated using factor analysis and multilevel regression modeling. Results: There were no significant differences in the OHIP-14 scores between week 1 and 5. Factors analysis revealed two OHIP-14 domains, ‘psychosocial’ and ‘physica‘. Individuals who improved their cognitive skills over study period and those with ‘severe’ periodontitis at baseline had increased scores of OHIP-14 ‘psychosocial’ domain. Individuals who improved orofacial health-related ‘motor’ skills over study period had decreased ‘physical’ domain scores. Increased cognition over study period, current smoking and dental calculus were associated with increased ‘physical’ domain. Conclusions: The OHRQoL was poor both at week 1 and 5. Individual’s cognitive and motor skills as well as their oral health status influenced their OHRQoL. Thus, individual’s awareness and involvement in addition to oral care seem to be imperative in improving the OHRQoL in neurorehabilitation setting.

BACKGROUND: Development of clinical practice at a Danish neurorehabilitation centre was delegated to a group of health professional developers. Their job function lacked conceptual foundation, and it was unclear how their working tasks contributed to evidence-based practice. OBJECTIVE: Conceptual clarification of the job function and pattern analysis of activity distributions for health professional developers. METHODS: Health professional developers kept continuous time geographical diaries for two weeks. Meaningful categories were subtracted through content analysis. Patterns were analysed within activity distributions with regards to evidence-based practice. RESULTS: A total of 213 diaries were collected from 21 health professional developers of three professions (physiotherapists, occupational therapists and nurses). Each participant reported 6–13 workdays (median 10 days). Eleven main categories of work tasks emerged with 42 subcategories. Overall, 7% of total time reported was spent on external knowledge, with minimal variation between professions and contractual time allocation. CONCLUSION: Conceptual clarification of work tasks was established for health professional developers. Their work activity distributions contributed mainly to maintenance of existing level of professional knowledge rather than to implementation of new knowledge, which did not fulfil the intended responsibility for development of evidence-based practice. Educational competence boost and data-driven change of organisation structure was recommended.

Objective To assess self-reported executive dysfunction in young adult patients with persistent post-concussion symptoms (PCS) 2–6 months post-injury, and the association with self-reported Health-Related Quality of Life (HRQoL). Method This cross-sectional study carried out in a hospital setting was a secondary analysis of data from a separate randomized trial testing the effect of a novel intervention, “Get going After concussIoN ” (GAIN), for persistent PCS. Patients (18–30 years) were recruited from a clinical cohort of patients with a hospital diagnosis of concussion or referred by primary care physicians. Main measures were The Behaviour Rating Inventory of Executive Function—Adult Version providing two index scores, that is, the Metacognitive Index (MI) and the Behavioural Regulation Index (BRI), and the Quality of Life after Brain Injury—Overall Scale. Results Compared with normative data, patients had elevated scores (i.e., worse functioning) on both the MI and the BRI. In linear regression analysis, the MI score, but not the BRI score, was negatively associated with self-reported HRQoL (MI: slope = −.27, 95% confidence interval, CI [−.53, −.02], p = .03; BRI: slope = −.19, 95% CI [−.49, .13], p = .24), suggesting a positive association of subjective executive dysfunction and lower HRQoL. However, the association was attenuated after adjustment for self-reported psychological distress (MI: slope = −.09, 95% CI [−.34, .17], p = .51). Conclusion Self-reported executive dysfunction is common in young adult patients with persistent PCS, but not strongly associated with decreased HRQoL after adjusting for concurrent psychological distress.

Background The Predict Recovery Potential algorithm (PREP2) was developed to predict upper limb (UL) function early after stroke. However, assessment in the acute phase is not always possible. Objective To assess the prognostic accuracy of the PREP2 when applied in a subacute neurorehabilitation setting. Methods This prospective longitudinal study included patients ≥18 years old with UL impairment following stroke. Patients were assessed in accordance with the PREP2 approach. However, 2 main components, the shoulder abduction finger extension (SAFE) score and motor-evoked potentials (MEPs) were obtained 2 weeks poststroke. UL function at 3 months was predicted in 1 of 4 categories and compared with the actual outcome at 3 months as assessed by the Action Research Arm Test. The prediction accuracy of the PREP2 was quantified using the correct classification rate (CCR). Results Ninety-one patients were included. Overall CCR of the PREP2 was 60% (95% CI 50%-71%). Within the 4 categories, CCR ranged from the lowest value at 33% (95% CI 4%-85%) for the category Limited to the highest value at 78% (95% CI 43%-95%) for the category Poor. In the present study, the overall CCR was significantly lower ( P < .001) than the 75% reported by the PREP2 developers. Conclusions The low overall CCR makes PREP2 obtained 2 weeks poststroke unsuited for clinical implementation. However, PREP2 may be used to predict either excellent UL function in already well-recovered patients or poor UL function in patients with persistent severe UL paresis.

Objective: To estimate national frequency of posttraumatic epilepsy (PTE) after severe traumatic brain injury (TBI) and assess injury severity (Glasgow Coma Scale (GCS) and posttraumatic amnesia (PTA)) as prognostic factors for PTE. Methods: Data on patients ≥18 years surviving severe TBI 2004–2016 were retrieved from the Danish Head Trauma Database (n = 1010). The cumulative incidence proportion (CIP) was estimated using death as competing event. The association between injury severity and PTE was assessed using multivariable competing risk regressions. Results: CIP of PTE 28 days and one year post-TBI was 6.8% (95% confidence interval (CI) 5.4–8.5) and 18.5% (95% CI 16.1–21.1%), respectively. Injury severity was not associated with PTE within 28 days post-TBI but indicated higher PTE-rates in less severely injured patients. PTA-duration >70 days was associated with PTE 29–365 days post-TBI (Adjusted sub-hazard ratio 4.23 (95% CI 1.79–9.99)). GCS was not associated with PTE 29–365 days post-TBI. Conclusion: The PTE frequency was higher compared to previous estimates. Increasing injury severity was associated with PTE 29–365 days post-TBI when measured with PTA, but not with GCS. Though nonsignificant, the increased PTE-risk within 28 days in lower severity suggests an underdiagnosing of PTE.

Background: Blood flow restriction exercise (BFR-E) could be a useful training adjunct for patients with weakness after stroke to augment the effects of exercise on muscle activity. We aimed to examine neurophysiological changes (primary aim) and assess patient perceptions (secondary aim) following BFR-E. Methods: Fourteen participants with stroke performed BFR-E (1 session) and exercise without blood flow restrictsion (Exercise only) (1 session), on two days, ≈7 days apart. In each session, two sets of tibialis anterior (TA) contractions were performed and electromyography (EMG) was recorded. Eight participants underwent transcranial magnetic stimulation (single-pulse stimulation, short interval intracortical inhibition (SICI), intracortical facilitation (ICF)) and peripheral electrical stimulation (maximal peak-to-peak M-wave (M-max)) of the TA before, immediately-after, 10-min-after and 20-min-after BFR-E and Exercise only. Numerical rating scores (NRS) for pain, discomfort, fatigue, safety, focus and difficulty were collected for all subjects (n = 14). Paired comparisons and linear mixed models assessed the effects of BFR-E and Exercise only. Results: No adverse events due to exercise were reported. There was no contraction-number x condition interaction for EMG amplitude during exercise (p = 0.15), or time x condition interaction for single-pulse stmulation, SICI, ICF or M-max amplitude (p = 0.34 to p = 0.97). There was no difference between BFR-E and Exercise only in NRS scores (p = 0.10 to p = 0.50). Conclusion: Using our training paradigm, neurophysiological parameters, feasibility, tolerability and perceptions of safety were not different between BFR-E and Exercise only. As participants were generally well-functioning, our results are not generalizable to lower functioning people with stroke, different (more intense) exercise protocols or longer term training over weeks or months.

Background: Patients with severe acquired brain injury (sABI) are likely to have a disturbed circadian rhythm in the early phase of neurorehabilitation. Circadian rhythm and sleep play an important role in the rehabilitation of patients with severe acquired brain injury (sABI). Research has also pointed out the importance of investigating novel ways of assessing sleep and circadian rhythm in patients with acquired brain injury. Established methods fail to apply to the heterogeneous and fluctuant biological or behavioral signals of the patients with sABI. Accelerometry (ACC) has proven a useful measure of circadian rhythm in sABI patients. However, ACC is unavailing if patients have limited motor activity due to a low consciousness level or severe paresis. Heart rate (HR) could be a viable alternative. In this study, we aim to present a novel model for the estimation of circadian rhythm and rhythm characteristics in both motor-active and -inactive patients using ACC and HR. Furthermore, we aim to present the results of the model in patients with sABI during their first three weeks of subacute in-hospital neurorehabilitation. Methods: An explorative observational study. Continuous recordings of ACC and electrocardiography were conducted. The suggested model was applied to examine circadian rhythms. Results: This study has proven the feasibility of a novel model for the analysis of circadian rhythm. Twenty-nine patients were included, 20 motor active and nine motor inactive. Estimates of rhythm characteristics have been presented along with estimates of circadian rhythm presence or absence for both groups. Conclusions: The model has been successfully applied in a population of patients with sABI. The circadian rhythm of patients undergoing in-hospital neurorehabilitation is fluctuating across time and highly variant between subjects within the first three weeks after admission to sub-acute neurorehabilitation.

Made available in DSpace on 2022-04-28T19:47:39Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-01 Health Research Fund of Central Denmark Region Objectives: To assess the internal structure and validity of the ‘bedside oral examination’ (BOE) instrument in individuals with acquired brain injury (ABI). Methods: Ninety ABI individuals were examined using BOE in their first week of neurorehabilitation. BOE measures oral health within eight categories including: swallow, tongue, odour, teeth, lips, saliva, mucosa and gingiva. To assess the validity of BOE, full-mouth clinical examination (gold standard) was performed. The internal structure of BOE was assessed using exploratory and confirmatory factor analyses. To measure the validity, the BOE scores were dichotomised into excellent oral health and altered oral health. Sensitivity, specificity and area under the receiver operating characteristic (ROC) curve of the six/eight BOE items were compared with their related clinical oral examination tool. Results: Overall, the patients had poor oral health irrespective of the oral examination tool used. Factor analyses indicated two factors within BOE: ‘oral hygiene’ (teeth, gingiva and mucosa) and ‘orofacial health’ (lips, swallow and saliva). BOE tongue and odour items loaded in neither factor. BOE items showed low validity since the highest area under the ROC curve was 0.60. Findings on the sensitivity value ranged from 35.0 to 74.2, while specificity from 44.4 to 83.3, depending on the item evaluated. Conclusion: Bedside oral examination does not seem to be an ideal ‘single’ outcome tool in a neurorehabilitation setting as it lacks validity. BOE evaluates oral health as two independent but correlated components and treat them separately indicating precision treatment depending on their oral health dysfunction. It is advisable to use BOE as a screening tool. However, it should be complimented by proper clinical examination before establishing a treatment plan for oral health in patients with ABI.

Sit-to-stand (STS) is a common transition movement needed to perform daily tasks. Previously, the kinematics of the STS movement has been investigated using optical motion capture. This method uses cameras and reflective markers on the body to capture movements. During STS, these markers can be difficult to measure due to blocked vision from the chair’s arm- and backrest. This can result in poor data quality. The aim of this study was to investigate 15 different marker protocols and compare them in terms of visibility and selected outcome measures: hip flexion mean angle and range of motion (ROM). Fourteen healthy subjects completed five successful trials of STS. Marker protocols consisted of three anterior marker protocols and five posterior marker protocols, combined into a total of 15 marker protocols. For visibility, the traditional pelvis marker protocol proved unsuitable for STS tracking. Marker pins or additional markers anteriorly, and sacrum markers posteriorly, proved to be more suitable alternatives. For hip flexion mean angle and ROM, the estimates had similar tendencies. Hence, marker protocols were not outcome measure specific. Anteriorly, marker pins resulted in similar estimates as the traditional pelvis marker protocol. Posteriorly, sacrum markers estimated a smaller hip flexion angle, compared to the traditional pelvis marker protocol. In conclusion, marker pins can be used instead of regular ASIS markers at anterior pelvis. Posteriorly, sacrum markers can be used instead of PSIS markers.

AIMS: Out-of-hospital cardiac arrest (OHCA) survivors may suffer short-term fatigue, psychological, cognitive and disability problems, but we lack information on the proportion of survivors with these problems in the long-term. Hence, we investigated these problems in survivors 1-5 years post-OHCA and whether the results are different at different time points post-OHCA.METHODS: All adults who survived an OHCA in Denmark from 2016 to 2019 were identified using the Danish Cardiac Arrest Registry and invited to participate in a survey between October 2020 and March 2021. The survey included the Modified Fatigue Impact Scale, Hospital Anxiety and Depression Scale, "Two simple questions" (everyday activities and mental recovery), and the 12-item World Health Organisation Disability Assessment Schedule 2.0. To investigate results at different time points, survivors were divided into four time-groups (12-24, 25-36, 37-48 and 49-56 months post-OHCA). Differences between time-groups were determined using the Kruskall-Wallis test for the mean scores and Chi-square test for the proportion of survivors with symptoms.RESULTS: Total eligible survey population was 2116, of which 1258 survivors (60%) responded. Overall, 29% of survivors reported fatigue, 20% anxiety, 15% depression, and 27% disability. When survivors were sub-divided by time since OHCA, no significant difference was found on either means scores or proportion between time groups (p=0.28 to 0.88).CONCLUSION: Up to a third of survivors report fatigue, anxiety, depression, reduced mental function and disability 1-5 years after OHCA. This proportion is the same regardless of how much time has passed supporting early screening and tailored post-OHCA interventions to help survivors adapt to their new situation.

Background The incidence of hospital-treated concussion is 100–300/100,000 person years. Reporting of long-lasting post-concussion symptoms (PCS) is estimated at 5–15%. Attachment insecurity is a potential vulnerability factor for physical illness and poorer disease outcomes in general. This study aimed to explore associations between attachment insecurity and PCS in young people sustaining a concussion. Methods This cross-sectional study was embedded in a cohort of 15–30-year-old patients (n = 3080) 3 months after sustaining a concussion. Data were obtained from a database and questionnaires. PCS were measured by the Rivermead Post-Concussion Symptoms Questionnaire and attachment dimensions (anxiety and avoidance) by the Experiences in Close Relationships-Relationship Structures Questionnaire. Multiple linear regression models were performed to investigate the association between the attachment dimensions and PCS with adjustment for demographic, injury-related and psychological factors and with additional testing for interaction between the attachment dimensions. Results In the final study sample, comprising 973 patients (31.6%), we found an interaction between the attachment dimensions. Hence, the effect of attachment anxiety on PCS was statistically insignificant at low avoidance (25th percentile) but significant at high avoidance (75th percentile, β = 0.64 (95%CI: 0.02; 1.26)), whereas the effect of attachment avoidance was significant regardless of level of attachment anxiety (25th percentile, β = 1.09 (95%CI: 0.18; 2.01); 75th percentile, β = 2.71 (95%CI: 1.80; 3.61)). Conclusion Attachment insecurity, especially characterised by high avoidance in combination with high anxiety, also called fearful attachment, is associated with PCS. Considering the attachment perspective can potentially improve health care for this patient group.

INTRODUCTION: We hypothesised that reduced shoulder function post stroke improves during constraint-induced movement therapy and that improvement in scapula upward rotation measured with three-dimensional kinematics is associated with improvements in clinical and patient reported outcomes.METHODS: Thirty-seven patients were tested pre and post constraint-induced movement therapy and again at three-month follow-up. Kinematic outcome measures - with scapula upward rotation as the primary outcome - during tasks 5 (ReachLow) and 6 (ReachHigh) from the Wolf Motor Function Test were included together with clinical and patient reported outcomes. Changes in outcome measures were analysed with linear mixed models and logistic regression analysis.FINDINGS: Scapula upward rotation was reduced from 16.2° pre intervention through 15.9° post intervention to 15.6° at three-month follow-up during ReachHigh. Statistically significant reductions of INTERPRETATION: The minimal improvements in selected 3D kinematic measures of upper extremity movements did not reflect any clinically meaningful changes. Therefore, the clinical and patient reported improvements could not be related to restitution of shoulder function.

Characteristics of persistent post-traumatic headache (PTH) in young individuals are poorly known leading to diagnostic problems and diverse management. We aimed to describe headache phenotypes and self-reported management strategies in young individuals with PTH following mild traumatic brain injury (mTBI). A comprehensive structured questionnaire was used to evaluate headache phenotypes/characteristics and management strategies to relieve headache in 107, 15–30-year-old individuals with PTH. Around 4 months post-injury, migraine-like headache in combination with tension-type like headache (40%) was the most commonly encountered headache phenotype followed by migraine-like headache (36%). Around 50% reported aura-like symptoms before/during the headache attack. Medication-overuse headache was diagnosed in 10%. Stress, sleep disturbances, and bright lights were the most common trigger factors. More than 80% reported that their headache was worsened by work-related activity and alleviated by rest/lying down. Simple analgesics were commonly used (88%) whereas prophylactic drugs were rarely used (5%). Bedrest and physiotherapy were also commonly used as management strategies by 56% and 34% of the participants, respectively. In conclusion, most young individuals with PTH after mTBI presented with combined migraine-like and tension-type-like headache followed by migraine-like headache, only. Preventive headache medication was rarely used, while simple analgesics and bedrest were commonly used for short-term headache relief.

IntroductionThe number of out-of-hospital cardiac arrest (OHCA) survivors is increasing. However, there remains limited knowledge on the long-term physical and psychological problems suffered by survivors and their relatives. The aims of the DANCAS (DANish cardiac arrest survivorship) survey are to describe the prevalence of physical and psychological problems, identify predictors associated with suffering them and to determine unmet rehabilitation needs in order to make recommendations on the timing and content of future rehabilitation interventions.Methods and analysisThe DANCAS survey has a cross-sectional design involving a survey of OHCA survivors and their relatives. OHCA survivors will be identified through the Danish Cardiac Arrest Registry as having suffered an OHCA between 1 January 2016 and 31 December 2019. Each survivor will be asked to identify their closest relative to complete the relatives’ survey. Contents of survivor survey: EQ-5D-5Level, Hospital Anxiety and Depression Scale, Two Simple Questions, Modified Fatigue Impact Scale, 12-item WHO Disability Assessment Scale 2.0, plus questions on unmet rehabilitation and information needs. Contents of relatives’ survey: World Health Organisation-Five Well-Being Index, Hospital Anxiety and Depression Scale, Informant Questionnaire on Cognitive Decline in the Elderly—Cardiac Arrest and the Modified Caregiver Strain Index. Self-report outcome data collected through the surveys will be enriched by data from Danish national registries including demographic characteristics, circumstances of cardiac arrest and comorbidities. The survey will be completed either electronically or by post December 2020–February 2021.Ethics and disseminationThe study will be conducted in accordance with the Declaration of Helsinki. Surveys and registry-based research studies do not normally require ethical approval in Denmark. This has been confirmed for this study by the Region of Southern Denmark ethics committee (20192000-19). Results of the study will be disseminated via several peer-reviewed publications and will be presented at national and international conferences.

Purpose: To develop and validate an accelerometer-based algorithm classifying physical activity in people with acquired brain injury (ABI) in a laboratory setting resembling a real home environment. Materials and methods: A development and validation study was performed. Eleven healthy participants and 25 patients with ABI performed a protocol of transfers and ambulating activities. Activity measurements were performed with accelerometers and with thermal video camera as gold standard reference. A machine learning-based algorithm classifying specific physical activities from the accelerometer data was developed and cross-validated in a training sample of 11 healthy participants. Criterion validity of the algorithm was established in 3 models classifying the same protocol of activities in people with ABI. Results: Modeled on data from 11 healthy and 15 participants with ABI, the algorithm had a good precision for classifying transfers and ambulating activities in data from 10 participants with ABI. The weighted sensitivity for all activities was 89.3% (88.3–90.4%) and the weighted positive predictive value was 89.7% (88.7–90.7%). The algorithm differentiated between lying and sitting activities. Conclusion: An algorithm to classify physical activities in populations with ABI was developed and its criterion validity established. Further testing of precision in home settings with continuous activity monitoring is warranted.

ObjectiveTo externally validate recent prognostic models that predict independent gait following stroke.Study design and settingA systematic search identified recent models (ResultsThree prognostic models met our criteria, all with high Risk of Bias. Validation data was only available for the Australian model. This model used National Institute of Health Stroke Scale (NIHSS) and age to predict independent gait, using Motor Assessment Scale (MAS) walking item. For validation, Scandinavian Stroke Scale (SSS) was a proxy for NIHSS, and Functional Independence Measure (FIM) locomotion item was a proxy for MAS. The Area Under the Curve was 0.77 (0.74-0.80) and had good calibration in the validation dataset. Adjustment of the intercept and regression coefficients slightly improved discrimination. By adding paretic leg strength, the model further improved (AUC 0.82).ConclusionExternal validation of the Australian model with proxies showed fair discrimination and good calibration. Updating the model by adding paretic leg strength further improved model performance.

A recent randomized controlled trial in young patients with long-term post-concussion symptoms showed that a novel behavioral intervention "Get going After concussIoN" is superior to enhanced usual care in terms of symptom reduction. It is unknown whether these interventional effects are associated with microstructural brain changes. The aim of this study was to examine whether diffusion-weighted MRI indices, which are sensitive to the interactions between cellular structures and water molecules' Brownian motion, respond differently to the interventions of the above-mentioned trial and whether such differences correlate with the improvement of post-concussion symptoms. Twenty-three patients from the intervention group (mean age 22.8, 18 females) and 19 patients from the control group (enhanced usual care) (mean age 23.9, 14 females) were enrolled. The primary outcome measure was the mean kurtosis tensor, which is sensitive to the microscopic complexity of brain tissue. The mean kurtosis tensor was significantly increased in the intervention group (p = 0.003) in the corpus callosum but not in the thalamus (p = 0.78) and the hippocampus (p = 0.34). An increase in mean kurtosis tensor in the corpus callosum tended to be associated with a reduction in symptoms, but this association did not reach significance (p = 0.059). Changes in diffusion tensor imaging metrics did not differ between intervention groups and were not associated with symptoms. The current study found different diffusion-weighted MRI responses from the microscopic cellular structures of the corpus callosum between patients receiving a novel behavioral intervention and patients receiving enhanced usual care. Correlations with improvement of post-concussion symptoms were not evident.

A lesion to the right hemisphere of the brain in humans commonly leads to perceptual neglect of the left side of the sensorium. The clinical observation that lesions to disparate cortical and subcortical areas converge upon similar behavioural symptoms points to neglect as a dysconnection syndrome that may result from the disruption of a distributed network, rather than aberrant computations in any particular brain region. To test this hypothesis, we used Bayesian analysis of effective connectivity based on electroencephalographic recordings in ten patients (6 male, 4 female; age range 41–68) with left-sided neglect following a right-hemisphere lesion. In line with previous research, age-matched healthy controls showed a contralateral increase in connection strength between parietal and frontal cortex with respect to the laterality of audiospatial oddball stimuli. Neglect patients, however, showed a dysconnection between parietal and frontal cortex in the right hemisphere when oddballs appeared on their left side, but preserved connectivity in the left hemisphere when stimuli appeared on their right. This preserved fronto-parietal connectivity was associated with lower neglect severity. Moreover, we saw ipsilateral fronto-temporal connectivity increases for oddballs appearing on the neglected side, which might be a compensatory mechanism for residual left side awareness. No group differences were found in intrinsic (within-region) connectivity. While further validation is required in a bigger sample, our findings are in keeping with the idea that neglect results from the disruption of a distributed network, rather than a lesion to any single brain region. Significance statement: Lesions to the right hemisphere of the brain commonly lead to neglect syndrome, characterized by perceptual deficits where patients are unaware of the left side of their body and environment. Using analysis of non-invasive electrophysiological recordings, we provide evidence that patients with left-sided neglect have reduced connectivity between the right parietal and frontal cortex during audiospatial stimuli, but preserved connectivity between regions in the non-lesioned left hemisphere. Moreover, for these intact connections we observed an ipsilateral fronto-temporal increase in connectivity during oddballs appearing on the neglected side, which might be a compensatory mechanism for residual perception. Crucially, we found that patients with more severe neglect symptoms had reduced connectivity between parietal and frontal cortex in the left hemisphere. This suggests that neglect may be caused by the disruption of a distributed network in the brain, rather than a lesion to any particular brain region.

Background Patients surviving out-of hospital cardicac arrest, with good neurological outcome according to Cerebral Performance Category, frequently have neuropsychological impairment. We studied whether biomarker data (S-100b and neuron-specific enolase) obtained during the ICU stay predicted cognitive impairment 6 months after resuscitation. Methods Patients (N = 79) with a CPC-score ≤2 were recruited from two trial sites taking part in the TTH48 trial comparing targeted temperature management (TTM) for 48 h vs. 24 h at 33 ± 1 °C. We assessed patients 6 months after the OHCA. We measured biomarkers S-100b and NSE at arrival and at 24, 48 and 72 h after reaching the target temperature of 33 ± 1 °C. Four cognitive domain z-scores were calculated, and global cognitive impairment was defined as z

PurposeFree of charge physiotherapy (FCP) is free physiotherapy provided by the Danish government for patients with a range of chronic diseases. To date, the population has not been described in depth making evaluation and decision making difficult. The purpose of this study was to (1) describe the development and the content of a novel clinical physiotherapy database for FCP (PhysDB-FCP) and (2) present the cohort profile based on the data collected.ParticipantsNinety-nine clinics (17 460 FCP patients) were invited to participate in the development process from 2018 to 2019. Eleven clinics consented (2780 FCP patients) and 534 patients performed the physiotherapy assessment using the PhysDB-FCP tool, with 393/534 completing the patient survey.Findings to dateThe content of the PhysDB-FCP was developed through an iterative process involving consensus between clinical and research workgroups. Prior to using the tool all consenting sites received training to use/administer the tool. All data were collected/stored using the PhysDB-FCP. Items finally chosen for the PhysDB-FCP included demographic information, questions about health status and daily functioning, functional tests, treatment plan and validated questionnaires. The initial patient cohort composed of 63.4% women with main diagnoses of multiple sclerosis (22.7%) and Parkinson’s disease (17.0%). The ability to perform personal/instrumental activities of daily living and functional ability varied widely. Other non-physiotherapy related issues were identified in numerous patients (ie, 34.9% of patients were at risk of depression) and multidisciplinary interventional approaches could be considered.Future plansThe current study has provided a comprehensive description of patients receiving FCP, using data collected from the novel PhysDB-FCP. Collected information can be used to facilitate microlevel to macrolevel programme evaluation and decisions. Although the PhysDB-FCP is promising, the tool requires optimisation before it is implemented regionally and/or nationally.

Background Affective and cognitive sequelae are frequently reported in cardiac arrest survivors; however, little is known about the risk factors. We assessed the hypothesis that self-reported affective and cognitive sequelae six months after OHCA may be associated with demography, acute care and cerebral outcome. Methods This is a sub-study of the multicentre “Target Temperature Management for 48 vs. 24 h and Neurologic Outcome after Out-of-Hospital Cardiac Arrest: A Randomised Clinical Trial” (the TTH48 trial) investigating the effect of prolonged TTM at 33 ± 1 °C. We invited patients with good outcome on the Cerebral Performances Categories (CPC score ≤ 2) to answer questionnaires on anxiety, depression, emotional distress, perceived stress and cognitive failures six months post OHCA. Results In total 79 of 111 eligible patients were included in the analysis. There were no significant differences in baseline characteristics between the included group and the group lost to follow-up. Younger age was a negative predictor across all self-reported outcomes, even when controlling for gender, ROSC time, treatment allocation, cognitive impairment and global outcome (CPC 1 or 2). Female gender was a predictor of anxiety, though this should be interpreted cautiously as only eight women participated. A CPC score of 2 score was a negative predictor of self-reported affective outcomes, albeit not for self-reported cognitive failures. Conclusion Younger age was associated with higher levels of self-reported affective and cognitive sequelae six months post OHCA. Female gender may be associated with self-reported anxiety. A higher CPC score may be a proxy for self-reported affective sequelae.

To compare stroke-specific health related quality of life in two country-regions with organisational differences in subacute rehabilitation services, and to reveal whether organisational factors or individual factors impact outcome. A prospective multicentre study with one-year follow-up of 369 first-ever stroke survivors with ischaemic or haemorrhagic stroke, recruited from stroke units in North Norway (n = 208) and Central Denmark (n = 161). The 12-domain Stroke-Specific Quality of Life scale was the primary outcome-measure. The Norwegian participants were older than the Danish (Mage= 69.8 vs. 66.7 years, respectively), had higher initial stroke severity, and longer stroke unit stays. Both cohorts reported more problems with cognitive, social, and emotional functioning compared to physical functioning. Two scale components were revealed. Between-country differences in the cognitive-social-mental component showed slightly better function in the Norwegian participants. Depression, anxiety, pre-stroke dependency, initial stroke severity, and older age were substantially associated to scale scores. Successful improvements in one-year functioning in both country-regions may result from optimising long-term rehabilitation services to address cognitive, emotional, and social functioning. Stroke-Specific Quality of Life one-year post-stroke could be explained by individual factors, such as pre-stroke dependency and mental health, rather than differences in the organisation of subacute rehabilitation services.IMPLICATIONS FOR REHABILITATIONThe stroke-specific health related quality of life (SS-QOL) assessment tool captures multidimensional effects of a stroke from the perspective of the patient, which is clinically important information for the rehabilitation services.The cognitive-social-mental component and the physical health component, indicate specific functional problems which may vary across and within countries and regions with different organisation of rehabilitation services.For persons with mild to moderate stroke, longer-term functional improvements may be better optimised if the rehabilitation services particularly address cognitive, emotional, and social functioning.

Introduction: In Denmark specialized neurorehabilitation(SN) in patients with severe acquired brain injury(SABI) is centralised in two centres. In west neurorehabilitation is managed by Hammel Neurocentre(HNC). The NeuroIntensive Stepdown Unit(NISU) at Silkeborg Regional Hospital offers intensive care in addition to SN in patients en route to HNC. Knowledge on patients’ characteristics and course in the setting of NISU is sparse. Objective: To characterise NISU patients and change in function and to identify variables associated with referral from NISU to HNC. Methods: Data on functional scores and relevant covariates was extracted from hospital records on 251 patients admitted from 01.11.2011–31.07.2016. Statistical methods included logistic regression and paired tests. Results: Mean(SD) time from injury to NISU admission was 30(22) days, medians(IQR) of Functional Independence Measure(FIM) and Early Functional Abilities(EFA) increased from 18(18,19) to 24(18,44) and 37(30,46) to 52(43,70) respectively from admission to discharge, both significant (p

To investigate the construct validity of the Functional Oral Intake Scale (FOIS) as a proxy measure for dysphagia, through associations with swallowing prerequisites, orofacial functions, age, and diagnosis; and to investigate content validity through distributions of FOIS ratings. Methods: A cohort of 1,876 patients with severe acquired brain injury. Early Functional Abilities items were applied as measures of swallowing prerequisites and orofacial functions. Clustered logistic regression model with 6,052 cross-sectional observations. Results: Disturbance in swallowing 10.55 OR 9 (95%CI:7.90;14.09), oro-facial stimulation 3.04 OR (95%CI:2.41;3.83), and head control 2.86 OR (95%CI:2.25;3.62) were robustly associated with tube feeding (FOIS 1-3). Disturbance in trunk control, wakefulness, tongue movement/chewing, older age, and a non-stroke diagnosis were also associated with tube feeding. BMI did not attenuate associations in sensitivity analyses. FOIS ratings had greatest density in FOIS evel 1 and level 7, with 25% and 40% of registrations, respectively. Level 4 was rated in only 1% of 6,052 registrations. Conclusions: The FOIS was robustly associated with indicators of dysphagia. However, associations with postural control, wakefulness, age and diagnosis highlights that tube feeding may be attributed to other issues than dysphagia. It should be further investigated whether FOIS level 4 is meaningful in neurorehabilitation.

Patients High or excessive parafunctional jaw muscle activity is a frequent complication of acquired brain injury (ABI) and may have some similarities to bruxism. Bruxism has been associated with increased tooth wear, masseter hypertrophy and headaches. The aim of this observational study was to identify the levels of jaw muscle activity from fourteen ABI patients having different functional and cognitive levels in their early phase of neurological rehabilitation (according to their Ranchos Los Amigos Scale (RLAS) score). Nine patients were severely cognitive impairement (RLAS score 1–3): with no or little response to any external stimuli due to low arousal and five patients were with RLAS score 4–8: depending on responses to stimuli and confusion level i.e. defining that patients had enough arousal to respond and react and therefore were able to follow the instructions. A single-channel electromyographic (EMG) device was used to assess the jaw muscle EMG activity in ABI patients for two hours continuously at two different days. Discussion The mean (± SD) jaw muscle activity observed in patients with ABI was 46.9 ± 6.5 EMG events/h with a wide range between 1–163 EMG events/h but with no significant difference between days (P = 0.230). Conclusion Irrespective of functional and cognitive ability scores patients with ABI had a wide range of EMG activity. The use of ambulatory single-channel EMG devices might open a path for further studies to determine levels of jaw muscle activity associated with potential side effects in ABI patients.

Background A major goal of upper limb (UL) rehabilitation after stroke is to facilitate the use of the paretic arm in daily life activities. Purpose To examine if UL impairment two weeks after stroke can predict real-life UL use at three months. Furthermore, to identify additional factors which contribute to future UL use, and characteristics of patients who do not achieve normal UL use. Methods This study included patients with stroke ≥ 18 years. UL impairment was assessed by Fugl-Meyer upper extremity motor assessment (FM). Use ratio between affected and unaffected UL was assessed with accelerometers at three months after stroke. The association between FM score and UL use ratio was investigated with linear regression models and adjusted for secondary variables. Non-normal use was examined by a logistic regression. Results Eighty-seven patients were included. FM score two weeks after stroke predicted 38% of the variance in UL use ratio three months after stroke. A multivariate regression model predicted 55%, and the significant predictors were FM, motor-evoked potential (MEP) status, and neglect. Non-normal use could be predicted with a high accuracy based on MEP and/or neglect. In a logistic regression sensitivity for prediction of non-normal use was 0.93 and specificity was 0.75. Conclusion Better baseline capacity of the paretic UL predicted increased use of the arm and hand in daily life. Non-normal UL use could be predicted reliably based on the absence of MEPs and/or presence of neglect.

PRIMARY OBJECTIVES: We hypothesized that the microstructure of the corpus callosum, thalamus and hippocampus, as measured with diffusion and Mean of the Kurtosis Tensor (MKT) MRI, differs between healthy subjects and patients with extensive and minimal post-concussion symptoms (PCS) and that MKT measures correlate with PCS severity and self-reported cognitive symptoms.RESEARCH DESIGN: A cross-sectional study comparing patients with extensive PCS and patients with minimal PCS 2-5 months after mild traumatic brain injury (mTBI) with each other and with an external healthy control group.METHODS AND PROCEDURES: Diffusion MRI was obtained in 25 patients with extensive PCS and in 25 patients with minimal PCS as measured by the Rivermead Post-concussion Symptoms Questionnaire. The patients were matched on age, sex and time since accident. Data from an external healthy control group (n = 27) was included.MAIN OUTCOME AND RESULTS: There was no difference in MKT between the two groups with mTBI and no correlation between MKT and PCS. There was no difference between the three groups in other diffusion measures.CONCLUSIONS: Our results did not point to microstructural changes in the corpus callosum, thalamus and hippocampus in relation to PCS after mTBI.

Background It is important to monitor progress during rehabilitation of stroke patients. To that end, clinical function tests may be supported by three-dimensional kinematic measures. The aim of this study was to evaluate the inter- and intra-rater reliability of three-dimensional kinematic measures of shoulder movements in stroke patients with reduced shoulder function. Methods Seventeen patients were tested in three sessions by two trained raters. Three-dimensional motion capture was performed of the more affected upper extremity and the trunk. Measures of movements of the scapula and humerus related to the trunk, the trunk related to the laboratory, the forearm related to the humerus, and temporospatial measures were obtained during two reach tasks from the Wolf Motor Function Test, ReachLow and ReachHigh. Inter- and intra-rater reliability was quantified with intraclass correlation coefficients (ICC). Findings In general, range of movements of scapula, shoulder, trunk and elbow and movement time and reach length showed high inter-rater reliability ( ICC ∞ 0.84–0.98) and intra-rater reliability ( ICC ∞ 0.75–1.00), A minimum of five trials per task were required to achieve reliable ICC estimates. Interpretation Selected three-dimensional kinematic measures can be used reliably to evaluate specific movements of the shoulder in stroke patients with reduced shoulder function.

Objective: To test if prognostic performance is affected by prolonged targeted temperature management (TTM) in comatose out-of-hospital cardiac arrest patients using two recently proposed EEG pattern classification models. Methods: In this sub-study of the “Target Temperature Management for 48 vs. 24 hand Neurologic Outcome after Out-of-Hospital Cardiac Arrest: A Randomized Clinical Trial” EEGs of 20–30 min duration were collected 24 h and 48 h after reaching the target temperature of 33 ± 1 °C. We classified EEGs according to two EEG classification models by Westhall et al. (“highly malignant” “malignant” and “benign”) and Hofmeijer et al. (“unfavorable” “intermediate” and “favorable”). We tested prognostic ability against 6 months functional outcome using the Cerebral Performance Category score. Results: We recorded EEGs in 120 patients at 24 h and in 44 patients at 48 h. We found no difference in specificities or sensitivities of the two models between the two TTM groups (all p-values >0.19) or in prognostication at 24 h compared to 48 h (all p-values >0.13), except for the presence of EEG reactivity favoring prognostication at 24 h (p < 0.001). Being classified in the “benign” or “favorable” category was strongly associated with good outcome with specificities of 100% (90–100) and 97% (85–100) for the Westhall and Hofmeijer models respectively. Conclusions: We found no difference in the prognostic performance of the two studied EEG classification models during prolonged TTM for 48 h compared to standard duration, nor between EEG classification performed at 24 h versus 48 h after reaching target temperature. The two models performed best in good outcome prediction.

The aim of this prospective, descriptive cohort study is to describe the prevalence of lower bowel dysfunction, possible relationship to diagnosis and severity, use of laxatives, and defecation patterns in patients with acquired brain injury during inpatient rehabilitation. Enrollment consisted of all patients admitted to an inpatient rehabilitation hospital (n = 98) within a 3-month period and assessments of fecal incontinence and fecal constipation at admission were performed. Documentation of used laxatives, number of defecations, and the macroscopic form during 4 weeks was conducted. Analysis of variance and Kruskal-Wallis analyses were conducted using the statistical software package STATA v 12/IC. At admission 75% of the patients suffered from lower bowel dysfunction, which was related to the severity of injury and age but not major diagnosis or gender. Of these, 68% suffered from fecal incontinence and 32% from fecal constipation. Ninety percent of the patients received laxatives during the initial 28 days. After 28 days, 20% continued to receive laxative treatment. There was no difference between weekly defecations in patients who had functional constipation and patients who had no bowel dysfunction. There was a strong relationship between bowel dysfunction status and prescribed laxative treatment. These findings indicate that lower gastrointestinal dysfunction is a long-lasting, profound complication following an acquired brain injury.

BACKGROUND: Cognitive sequelae, most frequently memory, attention, and executive dysfunctions, occur commonly in out-of-hospital cardiac arrest (OHCA) survivors. Targeted temperature management (TTM) following OHCA is associated with improved cognitive function. However, the relationship between the duration of TTM and cognitive outcome remains unclear. We hypothesised that OHCA survivors that were subjected to prolonged TTM of 48 h (TTM48) would exhibit better cognitive functions compared to those subjected to standard TTM of 24 h (TTM24) six months post-OHCA.METHODS: A predefined, cognitive post-hoc sub-study was conducted on the multicentre clinical trial: "Target Temperature Management for 48 vs. 24 h and Neurologic Outcome after out-of-hospital cardiac arrest: A Randomised Clinical Trial" (the TTH48 trial). OHCA survivors with perceived good cognitive outcome (CPC score ≤ 2) were invited to a neuropsychological assessment of memory, attention, and executive functions six months post-OHCA.RESULTS: In total, 79 patients were included in the study. Multivariate regression analysis revealed that TTM48 was associated with a significant better performance on three of 13 cognitive tests specific to memory retrieval after adjusting for age at follow-up and time to return of spontaneous circulation. Overall, patients in the TTM24 group were almost three times more likely (RR = 2.9 (95% CI 1.1-7.4)), p = 0.02) to be cognitively impaired.CONCLUSIONS: This study reports an association between the duration of TTM and cognitive outcome. In OHCA survivors with perceived good cognitive outcome (CPC ≤ 2), TTM48 was associated with reduced memory retrieval deficits and lower relative risk of cognitive impairment six months after OHCA compared to standard TTM24.

PURPOSE: To test if the Rehabilitation Complexity Scale Extended (RCS-E) can be used as decision support for patient referral to primary rehabilitation as either complex specialized services (CSS) or district specialist services (DSS).METHOD: Two independent expert teams analyzed medical records on 299 consecutive patients admitted for CSS or DSS rehabilitation. One team provided a golden standard for the patient referrals, and the other team provided RCS-E scores. Models for predicting referrals from RCS-E scores were developed on data for 149 patients and tested on the remaining 150 patients.RESULTS: The optimal RCS-E sum score threshold for referral prediction was 11, predicting the golden standard for patient referral with sensitivity 88%, specificity 78% and correct classification rate 81%. Improved referral prediction performance was achieved by using RCS-E item-wise score thresholds (sensitivity 81%, specificity 89%, correct classification rate 87%). The RCS-E sum score range for patients referred CSS and DSS by the item-wise model was, respectively, 0-12 and 2-22 suggesting strong non-linear interaction of the RCS-E items.CONCLUSIONS: We found excellent referral decision support in the RCS-E and the item specific threshold model, when patients with acquired brain injury are to be referred to CSS or DSS as their primary rehabilitation. Implications for Rehabilitation Efficient rehabilitation after acquired brain injury requires rehabilitation settings that meet patient needs. Validated tools for referral decision support make the process more transparent. Patient rehabilitation complexity can be stratified by the RCS-E with high sensitivity, specificity and predictive value of positive test. RCS-E is an excellent tool for referral decision support.

PRIMARY OBJECTIVE: To perform a detailed clinical oral health assessment and oral-health-related social and behavioural aspect assessment in individuals with acquired brain injury (ABI).RESEARCH DESIGN: Prospective observational study.METHODS AND PROCEDURES: Thirteen individuals with ABI were recruited. Individual's social and behavioural history, bed-side oral examination score (BOE), tooth condition and periodontal status (bleeding, plaque and clinical attachment loss) were thoroughly examined. The entire examination took up to 60 minutes, using proper dental armamentarium.MAIN OUTCOMES AND RESULTS: All evaluated individuals were diagnosed with chronic generalized periodontitis. A relationship between active periodontal disease and severe BOE score was observed (p = 0.01). Significant interaction between severe BOE scores (≥ 15 or ≥ 14) and periodontal disease severity of ≥ 2 mm (p = 0.01) was observed. The same interaction was seen between severe BOE scores and the combination of 75% extent and 2 mm severity (p = 0.01). Severity and activity of periodontitis showed dependence on individual brushing frequency (p = 0.03 and p = 0.05, respectively).CONCLUSIONS: Individuals with ABI had a poor status across a range of oral-, dental- and periodontal-related parameters. Further structured studies are required to define evidence-based assessment approaches for such clinical reality.

Elderly people represent the majority of stroke cases worldwide. Post-stroke sequelae frequently lead to a more isolated life. Restricted social relations render older individuals with stroke a vulnerable group, especially in terms of social reintegration. Reintegration into the community after a stroke largely depends on support from the family. However, close relatives are at risk of becoming overburdened. The aim of this study is to investigate the effect of a novel self-management intervention to support elderly people after stroke. Randomized controlled trial. Two weeks before discharge from a rehabilitation hospital/center, individuals with stroke aged textgreater 65 years will be randomized either to a group receiving conventional neurorehabilitation (control) or to an additional novel self-management intervention. In the intervention group, patients with stroke will be offered eight self-management sessions of 45–60 min duration by a physiotherapist or an occupational therapist during a period of nine months after discharge. Inclusion will continue until at least 35 individuals in each group have been recruited. Study outcome measurements: Stroke Self-efficacy Questionnaire, a short version of Stroke Specific Quality of Life Scale, Impact on Participation and Autonomy and Caregiver Burden Scale. Furthermore, physical activity will be assessed using accelerometers. All outcomes except “impact on participation” and “autonomy” will be assessed at baseline, three months, and nine months after discharge. Impact on participation and autonomy will be assessed at three and nine months after discharge. Patient, informal caregiver, and therapist satisfaction will be examined by way of questionnaires and interviews. Self-management interventions are promising strategies for rehabilitation, potentially increasing self-efficacy, quality of life, as well as participation and autonomy. The introduction of a novel self-management intervention in combination with traditional physical and occupational therapy may enhance recovery after stroke and quality of life and lessen the burden on relatives. This trial “Stroke - 65 Plus. Continued Active Life,” will provide further evidence of self-management strategies to clinicians, patients, and health economists. ClinicalTrials.gov, NCT03183960 .

Primary objective: Rehabilitation scales following neurological injury can be useful for monitoring patient progress. However, too often, rehabilitation scales are administered unnecessarily placing an extra burden on clinicians and patients. The primary objective was to reduce redundant testing by providing guidelines for the concurrent use of the Functional Independence Measure (FIM) and Early Functional Abilities (EFA) scales during rehabilitation in patients with brain injury.Methodology: In total, 3289 concurrent FIM and EFA scores from 929 patients were examined. We proposed, using clinically sound and operational criterion, that the FIM should be used throughout rehabilitation, EFA should be used as a supplement when the FIM is ≤36 and FIM should be administered before the EFA on each testing occasion.Results: Around 24% of patients should be measured with the FIM and EFA throughout rehabilitation, 35% of patients should be measured with the EFA and FIM initially but not require EFA measurements when there is an increase in function and 39% of patients should only be measured with the FIM. According to these guidelines, the EFA was administered unnecessarily 53% of the time.Conclusions and implications: These guidelines ensure that the EFA is used when it is sensitive. This will optimize clinician time and minimize redundant testing, without compromising the measurement of clinical progress.

Background Several predictors have been associated with upper extremity (UE) recovery after stroke, but characteristics that predict shoulder function after constraint-induced movement therapy (CIMT) have not yet been identified. Objectives To identify predictors associated with satisfactory shoulder function in patients with reduced shoulder function at admission to CIMT. Methods One hundred and seventy five patients were treated using CIMT while in a specialized inpatient hospital. Satisfactory shoulder function was defined according to the functional ability scale of the Wolf Motor Function test. Predictors of satisfactory shoulder function after CIMT were identified using multivariable logistic regression. Results Better distal arm function and good proximal shoulder function on admission to CIMT were strong predictors of satisfactory shoulder function, while age and time of admission to CIMT since stroke were not. Seventeen percent of all CIMT-participants with reduced shoulder function pre-CIMT reached a level of satisfactory shoulder function after CIMT. Discussion A substantial part of patients with reduced shoulder function reached a level of satisfactory shoulder function after CIMT. Intensive CIMT training, comprising tasks that require both distal and proximal UE function, may increase shoulder function in patients with a potential functional reserve.

Not least tuberculosis caused the growth of many spas. In Denmark, the Society for Physical Therapy and Dietetic was formed in 1902, and in 1921 it changed its name to the Danish Physiatrists Society, later the Danish Society for Physiatrists and Rehabilitation. In the early 1980's the National Board of Health decided, that all specialties should rehabilitate patients within their own area, and the specialty for rehabilitation was abolished. Therefore, all doctors need to have knowledge of the biopsychosocial model and the involvement of other professional groups and sectors.

Background We aimed to investigate the impact of prolonged targeted temperature management (TTM) in cardiac arrest patients on release of serum levels of NSE and S-100b and their prognostic performances. Methods This is a substudy of the Targeted Temperature Management for 24 vs 48 h trial. NSE and S-100b levels were analysed retrospectively in serum samples collected upon admission, at 24, 48, and 72 h after reaching the target temperature of 33 ± 1 °C. The primary outcome was biomarker serum concentrations and secondary outcome was the cerebral performance category score after 6 months. Results 115 patients from two centres were analysed. NSE and S-100b levels did not differ between TTM groups at any single time-point. Poor outcome patients had higher biomarker levels at 24, 48, and 72 h: NSE: 9.73 (7.2; 10.9) versus 20.40 (12.7; 27.2), 8.86 (6.6; 9.6) versus 17.47 (11.1; 37.3) and 6.23 (5.3; 8.5) versus 31.05 (12.8; 52.5) respectively and S-100b: 0.09 (0.07; 0.11) versus 0.23 (0.19; 0.39), 0.08 (0.07; 0.09) versus 0.18 (0.15; 0.33) and 0.07 (0.06; 0.08) versus 0.13 (0.09; 0.23). The daily changes in NSE from admission to Day 2 after the cardiac arrest (CA) were also related to the outcome (p = 0.003 and p = 0.02). The best prediction of outcome was found at 72 h for NSE and at 24 h as well as 48 h for S100b. Conclusions No clinically relevant differences were found in the levels of NSE or S-100b between standard and prolonged TTM. Prognostic reliability of NSE and S-100b was unaltered by prolonged TTM.

BACKGROUND There is a paucity of studies, which have described malnutrition in patients with acquired brain injury (ABI) across etiology. This study describes weight change, malnutrition, and potential associations in patients with ABI at a subacute inpatient rehabilitation hospital. METHOD This is a descriptive cohort study. Ninety-eight patients were admitted in a 3-month period, of whom n = 76 met inclusion criteria. The Malnutrition Universal Screening Tool was used for categorizing patients according to risk of malnutrition. RESULTS Patients had experienced weight loss of 5.59% ± 5.89% (p < .001) at admission at the rehabilitation hospital, and patients with traumatic brain injury had experienced a greater weight loss than patients with stroke (p < .01). Thirty percent of patients were at high risk for malnutrition, and 52% of these patients received enteral or parenteral nutrition at admission at the rehabilitation hospital. No association was found between risk of malnutrition and severity of injury, complications, functional outcome, or length of stay. CONCLUSION RESULTS underline the importance that nurses, especially in acute care, adhere to clinical guidelines to minimize weight loss. Special attention should be on patients with traumatic brain injury. Weight gain in the following course of rehabilitation may facilitate positive rehabilitation outcomes.

OBJECTIVE Patients with non-traumatic rupture of an aneurysm located at the anterior communicating artery (ACoA) often experience cognitive disabilities. It is unknown whether location of aneurysm also affects the possibility for improvement in functional independence compared to patients with an aneurysmal subarachnoid hemorrhage (a-SAH) located elsewhere. The aim was to explore the association between location of aneurysm (ACoA versus other) and level of functional independence, measured by Functional Independence Measure (FIM), at discharge from rehabilitation. Additionally, age and FIM at admission were explored. METHOD Historical cohort study among 107 patients with a-SAH based on data from a clinical database and a population-based register. Data were analyzed using multivariable logistic regression. RESULTS Patients with ACoA were admitted with poorer cognitive FIM (median 6 (IQR 5-14) compared to patients with aneurysms located elsewhere (median 12 (IQR 6-23) (p = 0.0129); no difference at discharge. No association between aneurysm location and functional independence was observed. Higher age was associated with poorer outcome in bowel management OR 0.54 (95% CI 0.31-0.92), bladder management OR 0.59 (95% CI 0.35-0.98), comprehension OR 0.53 (95% CI 0.30-0.94), and memory OR 0.48 (95% CI 0.25-0.93). Overall, FIM at admission was associated with functional independence at discharge with the exception of stair walking and bladder management which did not reach statistical significance. CONCLUSION ACoA was not associated with poorer level of functional independence compared to patients with a-SAH located elsewhere. Higher age was associated with poorer outcome in continence, comprehension, and memory, whereas higher FIM was associated with better functional independence across items at discharge.

© 2017 Informa UK Limited, trading as Taylor & Francis Group. The aim of the study was to assess the reliability and variability of stretch reflex magnitude (SRmag) in sub-acute stroke patients. For testing, rapid dorsiflexion stretches were induced 24 h apart in 22 patients and 34 controls. SRmag between sessions in patients and controls was not different and the SRmag on the more-affected side was significantly larger than the less-affected, dominant, and non-dominant sides. The SRmag was consistent between sessions. Therefore, patients were not as variable between sessions as we had hypothesized.

ObjectiveTo compare the changes in functional independence measured by the FIM after specialized neurorehabilitation between patients with nontraumatic subarachnoid hemorrhage (SAH) and patients with intracerebral hemorrhage (ICH) or acute ischemic stroke (AIS).DesignHistorical cohort study comparing changes in functional independence between patients with nontraumatic SAH and those with ICH/AIS, using FIM scores from a local database and clinical information from the Danish National Patient Registry.SettingPostacute specialized inpatient neurorehabilitation.ParticipantsParticipants (N=660) comprised patients with a first-time nontraumatic SAH (n=212) and age-matched patients with a first-time ICH/AIS (n=448).InterventionsNot applicable.Main Outcome MeasuresCrude and adjusted comparisons of FIM (total and item by item) measured at baseline and at discharge.ResultsPatients with nontraumatic SAH were admitted with a lower functional level compared with patients with ICH/AIS (median total FIM score, 25 [interquartile range (IQR), 18–81] vs 78.5 [IQR, 47–107]), and discharged with a lower functional level (median total FIM score, 98 [IQR, 40–116] vs 110 [IQR, 82.5–119]), although they made more progress during neurorehabilitation (median change in total FIM score, 27 [IQR, 4–60] vs 17 [IQR, 7–35]). Statistically, patients with nontraumatic SAH had significantly better odds for obtaining functional independence than did patients with ICH/AIS in 6 of the 18 FIM items: eating (odds ratio [OR]=3.2; 95% confidence interval [CI], 1.7–5.8); dressing–upper body (OR=2.0; 95% CI, 1.1–3.5); transfer tub/shower (OR=2.0; 95% CI, 1.1–3.6); stair walking (OR=2.2; 95% CI, 1.3–3.7); comprehension (OR=2.3; 95% CI, 1.3–3.9); and expression (OR=3.6; 95% CI, 2.0–6.5).ConclusionsPatients with nontraumatic SAH made significantly more progress during neurorehabilitation, although they were discharged with a lower level of functional independence compared with patients with ICH/AIS. However, both patients with nontraumatic SAH and those with ICH/AIS improved their functional outcome significantly. Also, patients with nontraumatic SAH admitted with severe functional outcome were shown to be capable of recovering to a moderate level of functional independence.

OBJECTIVE: To evaluate recreational and medical cannabis use in individuals with traumatic spinal cord injury, including reasons and predictors for use, perceived benefits and negative consequences.DESIGN: Cross-sectional survey in Denmark.METHODS: A 35-item questionnaire was sent to 1,101 patients with spinal cord injury who had been in contact with a rehabilitation centre between 1990 and 2012.RESULTS: A total of 537 participants completed the questionnaire. Of these, 36% had tried cannabis at least once and 9% were current users. Of current users, 79% had started to use cannabis before their spinal cord injury. The main reason for use was pleasure, but 65% used cannabis partly for spinal cord injury-related consequences and 59% reported at least good effect on pain and spasticity. Negative consequences of use were primarily inertia and feeling quiet/subdued. Lower age, living in rural areas/larger cities, tobacco-smoking, high alcohol intake and higher muscle stiffness were significantly associated with cannabis use. Those who had never tried cannabis reported that they would mainly use cannabis to alleviate pain and spasticity if it were legalized.CONCLUSION: Cannabis use is more frequent among individuals with spinal cord injury in Denmark than among the general population. High muscle stiffness and various demographic characteristics (lower age, living in rural areas/larger cities, tobacco-smoking and high alcohol intake) were associated with cannabis use. Most participants had started using cannabis before their spinal cord injury. There was considerable overlap between recreational and disability-related use.

Background and Purpose— Transcranial direct current stimulation may enhance effect of rehabilitation in patients with chronic stroke. The objective was to evaluate the efficacy of anodal transcranial direct current stimulation combined with constraint-induced movement therapy of the paretic upper limb. Methods— A total of 44 patients with stroke were randomly allocated to receive 2 weeks of constraint-induced movement therapy with either anodal or sham transcranial direct current stimulation. The primary outcome measure, Wolf Motor Function Test, was assessed at baseline and after the intervention by blinded investigators. Results— Both groups improved significantly on all Wolf Motor Function Test scores. Group comparison showed improvement on Wolf Motor Function Test in the anodal group compared with the sham group. Conclusions— Anodal transcranial direct current stimulation combined with constraint-induced movement therapy resulted in improvement of functional ability of the paretic upper limb compared with constraint-induced movement therapy alone.

Importance: International resuscitation guidelines recommend targeted temperature management (TTM) at 33°C to 36°C in unconscious patients with out-of-hospital cardiac arrest for at least 24 hours, but the optimal duration of TTM is uncertain.Objective: To determine whether TTM at 33°C for 48 hours results in better neurologic outcomes compared with currently recommended, standard, 24-hour TTM.Design, Setting, and Participants: This was an international, investigator-initiated, blinded-outcome-assessor, parallel, pragmatic, multicenter, randomized clinical superiority trial in 10 intensive care units (ICUs) at 10 university hospitals in 6 European countries. Three hundred fifty-five adult, unconscious patients with out-of-hospital cardiac arrest were enrolled from February 16, 2013, to June 1, 2016, with final follow-up on December 27, 2016.Interventions: Patients were randomized to TTM (33 ± 1°C) for 48 hours (n = 176) or 24 hours (n = 179), followed by gradual rewarming of 0.5°C per hour until reaching 37°C.Main Outcomes and Measures: The primary outcome was 6-month neurologic outcome, with a Cerebral Performance Categories (CPC) score of 1 or 2 used to define favorable outcome. Secondary outcomes included 6-month mortality, including time to death, the occurrence of adverse events, and intensive care unit resource use.Results: In 355 patients who were randomized (mean age, 60 years; 295 [83%] men), 351 (99%) completed the trial. Of these patients, 69% (120/175) in the 48-hour group had a favorable outcome at 6 months compared with 64% (112/176) in the 24-hour group (difference, 4.9%; 95% CI, -5% to 14.8%; relative risk [RR], 1.08; 95% CI, 0.93-1.25; P = .33). Six-month mortality was 27% (48/175) in the 48-hour group and 34% (60/177) in the 24-hour group (difference, -6.5%; 95% CI, -16.1% to 3.1%; RR, 0.81; 95% CI, 0.59-1.11; P = .19). There was no significant difference in the time to mortality between the 48-hour group and the 24-hour group (hazard ratio, 0.79; 95% CI, 0.54-1.15; P = .22). Adverse events were more common in the 48-hour group (97%) than in the 24-hour group (91%) (difference, 5.6%; 95% CI, 0.6%-10.6%; RR, 1.06; 95% CI, 1.01-1.12; P = .04). The median length of intensive care unit stay (151 vs 117 hours; P Conclusions and Relevance: In unconscious survivors from out-of-hospital cardiac arrest admitted to the ICU, targeted temperature management at 33°C for 48 hours did not significantly improve 6-month neurologic outcome compared with targeted temperature management at 33°C for 24 hours. However, the study may have had limited power to detect clinically important differences, and further research may be warranted.Trial Registration: clinicaltrials.gov Identifier: NCT01689077.
