Burnout is recognised as a significant occupational hazard for medical professionals. For graduate trainees, across various medical specialties, there is growing evidence burnout results in personal harm and reduces the quality of patient care. Rehabilitation medicine, with its challenge of emotional exhaustion bought about by greater involvement in patient psychosocial well-being over a prolonged period, is significantly under-represented in research into burnout prevalence, impact and prevention strategies. We argue the lack of any evidence base in the Australian healthcare context negatively impacts the ability of training organisations to appropriately support trainees experiencing burnout., (© 2022 Royal Australasian College of Physicians.)

Objective: To investigate whether diagnostic agreement and concordance between non-psychiatric (medical and surgical) doctors and consultation-liaison psychiatry changes within junior doctors' terms., Method: This was a retrospective cohort analysis of referrals from medical and surgical units to a consultation-liaison psychiatry service. Diagnostic agreement was calculated across all diagnoses and expressed as a percentage. Diagnostic concordance (expressed using Cohen's Kappa) was calculated for the two most common diagnoses of depression and delirium. Diagnostic agreement and concordance in the first two weeks (Timepoint A) were compared to those in the last two weeks (Timepoint B) of junior doctors' terms., Results: Around half the referrals (Timepoint A = 48.1%, Timepoint B = 54.0%) were excluded as no diagnosis was listed.Diagnostic agreement over all diagnoses was 31.7% (Timepoint A) and 29.9% (Timepoint B) and was not statistically different. Diagnostic concordance for depression increased from fair to moderate but was not statistically significant. Diagnostic concordance for delirium was substantial for both timepoints and were not statistically different., Conclusions: No statistically significant change in diagnostic accuracy over a junior doctors' term was found in this study.

Background: Early-onset sleep disturbance is common following moderate to severe traumatic brain injury (TBI) and often emerges while patients are in posttraumatic amnesia (PTA). However, sleep disruptions during this subacute recovery phase are not well-defined, and research often utilizes indirect measures (actigraphy) that quantify sleep based on activity. This study aims to examine sleep macro-architecture and sleep quality directly with ambulatory polysomnography (PSG) and measure endogenous salivary melatonin levels for patients experiencing PTA following moderate to severe TBI., Method: Participants were recruited from an inpatient TBI rehabilitation unit. Nighttime PSG was administered at the patient's bedside. Two saliva specimens were collected for melatonin testing on a separate evening (24:00 and 06:00 hours) using melatonin hormone profile test kits., Results: Of 27 patients in whom PSG was recorded, the minimum required monitoring time occurred in n =17 (adherence: 63%) at a median of 37.0 days (quartile 1 [Q1] to quartile 3 [Q3]: 21.5-50.5) postinjury. Median non-rapid eye movement (NREM) and REM sleep proportions were similar to normal estimates. Slow-wave sleep was reduced and absent in 35.3% of patients. Sleep periods appeared fragmented, and median sleep efficiency was reduced (63.4%; Q1-Q3: 55.1-69.2). Median melatonin levels at both timepoints were outside the normal range of values specified for this test (from Australian Clinical Labs)., Conclusion: This study reports that ambulatory PSG and salivary melatonin assessment are feasible for patients experiencing PTA and offers new insight into the extent of sleep disturbance. Further research is necessary to understand associations between PTA and sleep disturbance.

Background: Following stroke, individuals commonly experience persisting loss of function. Whilst long-term care should involve continued support for ongoing stroke sequelae, this is often not routinely practiced globally. The Post Stroke Checklist was designed to standardise the process of detecting persisting treatable problems following stroke., Aims: This cross-sectional study aimed to identify the long-term problems reported in Australian and Chinese participants at six months post stroke using the Post Stroke Checklist. It also aimed to provide global insight into poststroke sequelae by comparing the study results to previously published studies which administered the Post Stroke Checklist in other countries., Methods: Participants were recruited from two hospitals in Australia and one hospital in China. The Post Stroke Checklist consists of 11 problem areas commonly experienced after stroke. This study follows a sequence of studies which have applied the checklist to monitor long-term outcomes after stroke in Germany, Italy, Singapore, Sweden and the United Kingdom., Results: Comparisons between Australia (n = 112) and China (n = 97) demonstrated statistically significant differences on the Post Stroke Checklist items. Across all seven countries, collectively the most common persisting difficulties post-stroke related to: cognition, life after stroke, mood, mobility and activities of daily living. An analysis of means procedure compared individual countries for each checklist item against the overall group mean (all countries combined)., Conclusions: Globally, individuals report persisting functional difficulties following stroke. There appear to be differences in the proportions affected across the various countries, and healthcare systems may benefit from geographically tailoring post-stroke care., Competing Interests: Declaration of Competing Interest None., (Copyright © 2021 Elsevier Inc.

Objective: The aims of this study were to (1) evaluate the relationships between stationary and dynamic associated reaction (AR) tests in people with acquired brain injury using surface electromyography (sEMG) muscle activity and three-dimensional motion analysis kinematic measures and (2) assess the test-retest reliability of sEMG and seated tests of ARs., Design: Forty-two adults with acquired brain injury underwent AR testing with seated contralateral maximal voluntary isometric contraction tests and walking (self-selected and fast speeds). Associated reaction measurements included biceps brachii sEMG, elbow goniometry, and three-dimensional motion analysis kinematics during walking. Pearson correlations evaluated the relationships between seated and dynamic walking AR tests and between muscle activity and kinematic measures. Chronic participants were reassessed 1 wk later for reliability., Results: A strong (r = 0.65) and moderate (r = 0.53) relationship existed for biceps brachii sEMG during seated and walking tests at self-selected and fast walk, respectively. A weak to moderate relationship existed between biceps brachii sEMG and kinematics during walking and between seated and walking measures of ARs (r = 0.23-0.53). All tests had strong to very strong test-retest reliability (intraclass correlation coefficients, >0.78)., Conclusion: Seated contralateral maximal voluntary isometric contraction tests correlate only weakly to moderately with AR walking kinematics and moderately to strongly with biceps brachii activation during walking. Moderate relationships exist between sEMG and kinematics, indicating that they may provide different information for ARs., Competing Interests: Financial disclosure statements have been obtained, and no conflicts of interest have been reported by the authors or by any individuals in control of the content of this article., (Copyright © 2020 Wolters Kluwer Health, Inc.

The effect of high emissivity coatings on the radiative heat transfer in steam cracking furnaces is far from understood. To start, there is a lack of experimental data describing the emissive properties of the materials encountered in steam cracking furnaces. Therefore, spectral normal emissivity measurements are carried out, evaluating the emissive properties of refractory firebricks before and after applying a high emissivity coating at elevated temperatures. The emissive properties are enhanced significantly after applying a high emissivity coating. Pilot unit steam cracking experiments show a 5% reduction in fuel gas firing rate after applying a high emissivity coating on the refractory of the cracking cells. A parametric study, showing the effect of reactor coil and furnace wall emissive properties on the radiative heat transfer inside a tube-in-box geometry, confirms that a non-gray gas model is required to accurately model the behavior of high emissivity coatings. Even though a gray gas model suffices to capture the heat sink behavior of a reactor coil, a non-gray gas model that is able to account for the absorption and re-emission in specific bands is necessary to accurately model the benefits of applying a high emissivity coating on the furnace wall.

Introduction: Multi-trauma rehabilitation is delivered in a variety of hospital settings. However, it is unclear whether the proximity of rehabilitation to acute services has an effect on rehabilitation outcomes., Objective: To evaluate whether the primary outcomes of an inpatient multi-trauma rehabilitation program (functional outcome and length of rehabilitation stay) are impacted when rehabilitation is delivered in a unit co-located in an acute hospital compared with a unit located in a freestanding hospital. To also compare these outcomes at a national level using data provided by the Australasian Rehabilitation Outcomes Centre (AROC)., Design: Observational, retrospective audit study., Setting: An inpatient, orthopedic, multi-trauma rehabilitation unit that re-located from an acute co-located facility to a freestanding facility., Patients: Patients following multi-trauma injury admitted to the co-located rehabilitation unit (n = 216) or after its relocation to the freestanding rehabilitation unit (n = 186)., Methods: Data were audited from the patients' hospital medical records including demographics, injury characteristics, and rehabilitation outcome measures (Functional Independence Measure [FIM] and length of rehabilitation stay)., Outcome Measures: The primary outcome variables were motor FIM change (change in function between admission and discharge), FIM efficiency (functional gain per inpatient day), and length of rehabilitation stay., Results: There were no statistically significant differences between the two settings in terms of motor FIM change (adjusted for admission motor FIM score) and motor FIM efficiency. In general, there was no statistically significant difference in length of rehabilitation stay between settings (median: 26 vs 27 days). At a national level, the majority of facilities offering inpatient multi-trauma rehabilitation are co-located. Nationally, freestanding units resulted in a slightly greater motor FIM change (difference between median changes adjusted for baseline = -.5, 95% confidence interval [CI] = -2.5, -0.6, P = .0012)., Conclusions: There were no differences observed in outcomes between multidisciplinary rehabilitation programs in either setting. Optimizing the individual components of a rehabilitation program and improving staff skill sets should be a focus going forward., (© 2020 American Academy of Physical Medicine and Rehabilitation.)

Background: Abnormal upper limb movements frequently affect people with acquired brain injury (ABI) during walking. Three-dimensional motion analysis (3DMA) can quantify upper limb abnormality kinematically, with composite scores condensing multiple joint axes data into a single score., Research Question: Are 3DMA-derived composite scores valid (known-groups and convergent validity), reliable and able to quantify speed-related changes in abnormal upper limb movement during walking?, Methods: This observational study compared 42 adults with ABI and abnormal upper limb movements during walking with 36 healthy controls (HC) at a matched walking speed intention. Participants underwent 3DMA assessment of self-selected and fast walking speeds. Composite scores quantified the affected upper limb's kinematic abnormality. The Arm Posture Score arithmetic mean version (APSam) and 1.96 standard deviation reference-range scaled versions; the Kinematic Deviation Score mean (KDSm) and worst score (KDSw) were evaluated for association with each other and subjective abnormality rating (Pearson's 'r' correlation), test-retest reliability (intra-class correlation coefficient (ICC)), and ability to quantify speed-related changes in abnormal upper limb movement (Cohen's d effect size (ES), % change scores)., Results: Very strong correlations existed between composite scores. The KDSm under-classified upper limb abnormality, whereas the KDSw captured the majority of ABI participants. All scores had moderate-strong correlations with subjective rating of abnormal upper limb movements (r = 0.54 - 0.79) and very strong test-retest reliability (ICCs > 0.81). The APSam demonstrated a 16% (ES = 0.76) walking speed-related increase in upper limb abnormality, whilst decreases were demonstrated in the KDSm 26% (ES 0.90) and KDSw 35% (ES 0.96)., Significance: The APSam, KDSw, and number of abnormal joint axes comprehensively assess the whole upper limb abnormal movements, accurately classifies abnormality, and quantifies severity. This study illustrated notable presence of abnormal upper limb movements at self-selected walking speed and small increase at fast speeds. However, when scaled to HC variability, the fast walk kinematics became less abnormal due to increased HC movement variability., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Following traumatic brain injury (TBI), participating in education often provides a pathway for returning to a student's pre-injury life. In this paper, we explore themes related to adjustment and identity that emerged from students' reflections about their study journey. The data for this project are drawn from a longitudinal, predominantly qualitative investigation. Twelve students (aged: 17-32 years) completed up to three in-depth interviews over a period of 4-15 months, capturing a total of 30 time points. Data were analysed using grounded theory methods. A significant theme of "Is it Me or is it the Injury?" emerged from the context of students' descriptions of self, "Me" and thoughts about their injury, "The Injury." This emergent theme was indicative of the complex processes involved in adjusting and reshaping identity that arose from students' participation in education. The concepts identified in this research suggest that clinicians and educators must adopt a comprehensive, holistic and flexible approach to supporting students that can be adapted to reflect the individual and dynamic processes involved.

Background: Agitation is common in the early stages of recovery from traumatic brain injury (TBI), when patients are in post-traumatic amnesia (PTA). Agitation is associated with risk of harm to patients and caregivers. Recent guidelines recommend that agitation during PTA is managed using environmental modifications. Agitation is also frequently treated pharmacologically, with the use of atypical antipsychotics such as olanzapine among the most common. This is despite a lack of well-designed studies to support the use of antipsychotics within this context. This study will be a double-blind, placebo-controlled randomised controlled trial. We will examine the efficacy, safety, cost-effectiveness and outcomes associated with the use of olanzapine for reducing agitation in patients in PTA following TBI over and above recommended environmental management., Methods: Fifty-eight TBI rehabilitation inpatients who are in PTA and are agitated will receive olanzapine or placebo for the duration of PTA. All participants will additionally receive optimal environmental management for agitation. Measures of agitation, PTA and health will be undertaken at baseline. Treatment administration will begin at a dose of 5 mg daily and may be escalated to a maximum dose of 20 mg per day. Throughout the treatment period, agitation and PTA will be measured daily, and adverse events monitored weekly. Efficacy will be assessed by treatment group comparison of average Agitated Behaviour Scale scores during PTA. Participants will cease treatment upon emergence from PTA. Agitation levels will continue to be monitored for a further 2 weeks, post-treatment measures of health will be undertaken and cognitive and functional status will be assessed. Level of agitation and functional health will be assessed at hospital discharge. At 3 months post-discharge, functional outcomes and health service utilisation will be measured., Discussion: This trial will provide crucial evidence to inform the management of agitation in patients in PTA following TBI. It will provide guidance as to whether olanzapine reduces agitation over and above recommended environmental management or conversely whether it increases or prolongs agitation and PTA, increases length of inpatient hospitalisation and impacts longer term cognitive and functional outcomes. It will also speak to the safety and cost-effectiveness of olanzapine use in this population., Trial Registration: ANZCTR ACTRN12619000284167 . Registered on 25 February 2019.

Objective : This systematic review evaluated subacute sleep disturbance following moderate to severe traumatic brain injury (TBI) and the impact of secondary factors such as mood or pain. Methods : A comprehensive search strategy was applied to nine databases. Inclusion criteria included: adults ≥18 years, moderate and severe TBI and within 3 months of injury. Eligible studies were critically appraised using the McMaster Quantitative Critical Review Form. Study characteristics, outcomes, and methodological quality were synthesized. This systematic review was registered with PROSPERO (Registration number: CRD42018087799). Results : Ten studies were included. Research identified early-onset sleep disturbances; characterized as fragmented sleep periods and difficulty initiating sleep. Alterations to sleep architecture (e.g. rapid eye movement sleep) were reported. Sleep disturbance appears to associate with alterations of consciousness. Sleep disturbance tended to be particularly increased during the phase of post-traumatic amnesia (PTA) (78.7%). Conclusions : There is a limited amount of research available, which has inherent measurement and sample size limitations. The gold standard for measuring sleep (polysomnography) was rarely utilized, which may affect the detection of sleep disturbance and sleep architecture. Secondary factors potentially influencing sleep were generally not reported. Further evaluation on associations between sleep and PTA is needed.

Objective: The aim of this study is to determine inter-rater, test-retest and intra-rater reproducibility and responsiveness of subjective assessment of upper limb associated reactions in people with acquired brain injury using (1) the 'Qualifiers Scale' of the International Classification of Functioning, Disability and Health Framework, and (2) visually estimated elbow flexion angle during walking., Design: Observational study., Setting: A brain injury rehabilitation centre, Melbourne, Australia., Subjects: People with acquired brain injury and upper limb associated reactions and experienced neurological physiotherapists., Main Measures: The Qualifiers Scale applied to individual upper limb joints and global associated reaction on a 5-point scale (0-4), a summed upper limb severity score and visually estimated elbow flexion angle., Results: A total of 42 people with acquired brain injury (mean age: 48.4 ± 16.5 years) were videoed walking at self-selected and fast speeds. A subset of 30 chronic brain injury participants (mean time post injury: 8.2 ± 9.3 years) were reassessed one week later for retest reproducibility. Three experienced neurological physiotherapists (mean experience: 22.7 ± 9.1 years) viewed these videos and subjectively rated the upper limb associated reactions. Strong-to-very strong test-retest, intra- and inter-rater reproducibility was found for elbow flexion angle (ICC > 0.86) and the Qualifiers Scale applied to global and individual upper limb joints (ICC > 0.60). Responsiveness of change from self-selected to fast walking speed (mean increase 0.46 m/s) was highest for elbow flexion angle (effect size = 0.83) and low-to-moderate for the Qualifiers Scale., Conclusion: Subjectively rated associated reactions during walking demonstrated strong reproducibility and moderate responsiveness to speed change. The Qualifiers Scale and elbow flexion angle can both subjectively quantify associated reactions during walking in a clinical setting.

Background and Purpose- The aim of this trial was to determine the effect of additional upper limb rehabilitation following botulinum toxin-A for upper limb activity in chronic stroke. Methods- We conducted a multicenter phase III randomized trial with concealed allocation, blinded measurement, and intention-to-treat analysis. One hundred forty stroke survivors who were scheduled to receive botulinum toxin-A in any muscle(s) that cross the wrist because of moderate to severe spasticity after a stroke >3 months ago, who had completed formal rehabilitation and had no significant cognitive impairment. Experimental group received botulinum toxin-A plus evidence-based movement training while the control group received botulinum toxin-A plus a handout of exercises. Primary outcomes were goal attainment (Goal Attainment Scaling) and upper limb activity (Box and Block Test) at 3 months (end of intervention). Secondary outcomes were spasticity, range of motion, strength, pain, burden of care, and health-related quality of life. Results- In terms of goal attainment, the experimental group scored the same (mean difference, 2 T-score [95% CI, -2 to 7]) as the control group on the Goal Attainment Scale. In terms of upper limb activity, by 3 months the experimental group moved blocks at the same speed (mean difference, 0.00 blocks/s [95% CI, -0.02 to 0.01]) as the control group on the Box and Block Test. There were no differences between groups on any secondary outcome except strength, in favor of the experimental group (mean difference, 1.4 kg [95% CI, 0.2-2.7]). Conclusions- Findings suggest that additional intensive upper limb rehabilitation following botulinum toxin-A in chronic stroke survivors with a disabled upper limb is not effective.

Background: Upper limb associated reactions (ARs) are common in people with acquired brain injury (ABI). Despite this, there is no gold-standard outcome measure and no kinematic description of this movement disorder. The aim of this study was to determine the upper limb kinematic variables most frequently affected by ARs in people with ABI compared with a healthy cohort at matched walking speed intention., Methods: A convenience sample of 36 healthy control adults (HCs) and 42 people with ABI who had upper limb ARs during walking were recruited and underwent assessment of their self-selected walking speed using the criterion-reference three dimensional motion analysis (3DMA) at Epworth Hospital, Melbourne. Shoulder flexion, abduction and rotation, elbow flexion, forearm rotation and wrist flexion were assessed. The mean angle, standard deviation (SD), peak joint angles and total joint angle range of motion (ROM) were calculated for each axis across the gait cycle. On a group level, ANCOVA was used to assess the between-group differences for each upper limb kinematic outcome variable. To quantify abnormality prevalence on an individual participant level, the percentage of ABI participants that were outside of the 95% confidence interval of the HC sample for each variable were calculated., Results: There were significant between-group differences for all elbow and shoulder abduction outcome variables (p < 0.01), most shoulder flexion variables (except for shoulder extension peak), forearm rotation SD and ROM and for wrist flexion ROM. Elbow flexion and shoulder abduction were the axes most frequently affected by ARs. Despite the elbow being the most prevalently affected (38/42, 90%), a large proportion of participants had abnormality, defined as ±1.96 SD of the HC mean, present at the shoulder (32/42, 76%), forearm (20/42, 48%) and wrist joints (10/42, 24%)., Conclusion: This study provides valuable information on ARs, and highlights the need for clinical assessment of ARs to include all of the major joints of the upper limb. This may inform the development of a criterion-reference outcome measure or classification system specific to ARs.

The purpose of this paper is to discuss how knowledge of the biomechanics of walking can be used to inform the prescription of resistance exercises for people with mobility limitations. Muscle weakness is a key physical impairment that limits walking in commonly occurring neurologic conditions such as cerebral palsy, traumatic brain injury, and stroke. Few randomized trials to date have shown conclusively that strength training improves walking in people living with these conditions. This appears to be because (1) the most important muscle groups for forward propulsion when walking have not been targeted for strengthening, and (2) strength training protocols have focused on slow and heavy resistance exercises, which do not improve the fast muscle contractions required for walking. We propose a theoretical framework to improve exercise prescription by integrating the biomechanics of walking with the principles of strength training outlined by the American College of Sports Medicine to prescribe exercises that are specific to improving the task of walking. The high angular velocities that occur in the lower limb joints during walking indicate that resistance exercises targeting power generation would be most appropriate. Therefore, we propose the prescription of plyometric and ballistic resistance exercise, applied using the American College of Sports Medicine guidelines for task specificity, once people with neurologic conditions are ambulating, to improve walking outcomes. This new theoretical framework for resistance training ensures that exercise prescription matches how the muscles work during walking., (Copyright © 2019 American Congress of Rehabilitation Medicine.

Purpose: To evaluate if a changed physical environment following redesign of a hospital ward influenced neurological patient physical and social activity., Methods: A "before and after" observational design was used that included 17 acute neurological patients pre-move (median age 77 (IQR 69-85) years Ward A and 20 post-move (median age 70 (IQR 57-81) years Ward B. Observations occurred for 1 day from 08.00-17.00 using Behavioral Mapping of patient physical and social activity, and location of that activity. Staff and ward policies remained unchanged throughout. An Environmental Description Checklist of each ward was also completed., Results: Behavioral Mapping was conducted pre-/post-move with a total of 801 Ward A and 918 Ward B observations. Environmental Description Checklists showed similarities in design features in both neurological wards with similar numbers of de-centralized nursing stations, however there were more single rooms and varied locations to congregate in Ward B (30% more single-patient rooms and separate allied health therapy room). Patients were alone >60% of time in both wards, although there was more in bed social activity in Ward A and more out of bed social activity in Ward B. There were low amounts of physical activity outside of patient rooms in both wards. Significantly more physical activity occurred in Ward B patient rooms (median = 47%, IQR 14-74%) compared to Ward A (median = 2% IQR 0-14%), Wilcoxon Rank Sum test z = -3.28, p = 0.001., Conclusions: Overall, patient social and physical activity was low, with little to no use of communal spaces. However we found more physical activity in patient rooms in the Ward B environment. Given the potential for patient activity to drive brain reorganization and repair, the physical environment should be considered an active factor in neurological rehabilitation and recovery. Implications for Rehabilitation Clinicians should include consideration of the impact of physical environment on physical and social activity of neurological patients when designing therapeutic rehabilitation environments. Despite architectural design intentions patient and social activity opportunities can be limited. Optimal neurological patient neuroplasticity and recovery requires sufficient environmental challenge, however current hospital environments for rehabilitation do not provide this.

Introduction: Schizophrenia is increasingly conceived as a disorder of brain network connectivity and organization. However, reports of network abnormalities during the early illness stage of psychosis are mixed. This study adopted a data-driven whole-brain approach to investigate functional connectivity and network architecture in a first-episode psychosis cohort relative to healthy controls and whether functional network properties changed abnormally over a 12-month period in first-episode psychosis., Methods: Resting-state functional connectivity was performed at two time points. At baseline, 29 first-episode psychosis individuals and 30 healthy controls were assessed, and at 12 months, 14 first-episode psychosis individuals and 20 healthy controls completed follow-up. Whole-brain resting-state functional connectivity networks were mapped for each individual and analyzed using graph theory to investigate whether network abnormalities associated with first-episode psychosis were evident and whether functional network properties changed abnormally over 12 months relative to controls., Results: This study found no evidence of abnormal resting-state functional connectivity or topology in first-episode psychosis individuals relative to healthy controls at baseline or at 12-months follow-up. Furthermore, longitudinal changes in network properties over a 12-month period did not significantly differ between first-episode psychosis individuals and healthy control. Network measures did not significantly correlate with symptomatology, duration of illness or antipsychotic medication., Conclusions: This is the first study to show unaffected resting-state functional connectivity and topology in the early psychosis stage of illness. In light of previous literature, this suggests that a subgroup of first-episode psychosis individuals who have a neurotypical resting-state functional connectivity and topology may exist. Our preliminary longitudinal analyses indicate that there also does not appear to be deterioration in these network properties over a 12-month period. Future research in a larger sample is necessary to confirm our longitudinal findings.

Objectives: To evaluate construct validity and responsiveness of the Brachial Assessment Tool (BrAT), a new patient-reported outcome measure for people with traumatic brachial plexus injury (BPI), and to compare it to the Disabilities of the Arm, Shoulder and Hand (DASH) and the Upper Extremity Functional Index (UEFI)., Design: Cross-sectional study., Setting: Outpatient clinics., Participants: Adults (N=29; age range, 20-69y) with confirmed traumatic BPI., Interventions: Participants completed the BrAT 3 times over an 18-month period together with 16 DASH activity items and the UEFI. Evaluations were undertaken of construct validity, known-groups validity, 1-way repeated analysis of variance, and effect size., Main Outcome Measures: BrAT, DASH, and UEFI., Results: The BrAT demonstrated a moderate to low correlation with the DASH activity items (<0.7) and a large correlation with the UEFI (>0.7). According to known-groups validity, only the BrAT was able to discriminate between people who stated they could use their hand versus those who were unable to use their hand to perform activities. All measures indicated a significant effect for time with the exception of BrAT subscale 1. The effect size was highest for the BrAT but lower than expected (BrAT, .52-.40; DASH, .15; UEFI, .36)., Conclusions: These preliminary findings support the BrAT as a valid and responsive patient-reported outcome measure for adults with traumatic BPI. The BrAT activity items appear to be more targeted than the DASH or UEFI particularly for people with more severe BPI. The BrAT also appears to be measuring a different activity construct than the DASH and the UEFI. Further work is required to confirm these results with larger sample sizes., (Copyright © 2017 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.)

Background: Standard treatment for thyroid eye disease is with systemic corticosteroids. We aimed to establish whether orbital radiotherapy or antiproliferative immunosuppression would confer any additional benefit., Methods: CIRTED was a multicentre, double-blind, randomised controlled trial with a 2 × 2 factorial design done at six centres in the UK. Adults with active moderate-to-severe thyroid eye disease associated with proptosis or ocular motility restriction were recruited to the trial. Patients all received a 24 week course of oral prednisolone (80 mg per day, reduced to 20 mg per day by 6 weeks, 10 mg per day by 15 weeks, and 5 mg per day by 21 weeks) and were randomly assigned via remote computerised randomisation to receive either radiotherapy or sham radiotherapy and azathioprine or placebo in a 2 × 2 factorial design. Randomisation included minimisation to reduce baseline disparities in potential confounding variables between trial interventions. Patients and data analysts were masked to assignment, whereas trial coordinators (who monitored blood results), pharmacists, and radiographers were not. The radiotherapy dose was 20 Gy administered to the retrobulbar orbit in ten to 12 fractions over 2 to 3 weeks. Azathioprine treatment was provided for 48 weeks at 100-200 mg per day (dispensed as 50 mg tablets), depending on bodyweight (100 mg for <50 kg, 150 mg 50-79 kg, 200 mg for ≥80 kg). The primary outcomes were a binary composite clinical outcome score and an ophthalmopathy index at 48 weeks, and a clinical activity score at 12 weeks. The primary analysis was based on the intention-to-treat allocation and safety was assessed in all participants. This study is registered with ISRCTN, number 22471573., Findings: Between Feb 15, 2006, and Oct 3, 2013, 126 patients were recruited and randomly assigned to groups: 31 patients to radiotherapy plus azathioprine, 31 to sham radiotherapy and azathioprine, 32 to radiotherapy and placebo, and 32 to sham radiotherapy and placebo. Outcome data were available for 103 patients (54 for sham radiotherapy vs 49 for radiotherapy and 53 for placebo vs 50 for azathioprine), of whom 84 completed their allocated treatment of radiotherapy or sham radiotherapy and 57 continued to take azathioprine or placebo up to 48 weeks. There was no interaction betweeen azathioprine and radiotherapy (p interaction =0·86). The adjusted odds ratio (OR adj ) for improvement in the binary clinical composite outcome measure was 2·56 (95% CI 0·98-6·66, p=0·054) for azathioprine and 0·89 (0·36-2·23, p=0·80) for radiotherapy. In a post-hoc analysis of patients who completed their allocated therapy the OR adj for improvement was 6·83 (1·66-28·1, p=0·008) for azathioprine and 1·32 (0·30-4·84, p=0·67) for radiotherapy. The ophthalmopathy index, clinical activity score, and numbers of adverse events (161 with azathioprine and 156 with radiotherapy) did not differ between treatment groups. In both groups, the most common adverse events were mild infections. No patients died during the study., Interpretation: In patients receiving oral prednisolone for 24 weeks, radiotherapy did not have added benefit. We also did not find added benefit for addition of azathioprine in the primary analysis; however, our conclusions are limited by the high number of patients who withdrew from treatment. Results of post-hoc analysis of those who completed the assigned treatment suggest improved clinical outcome at 48 weeks with azathioprine treatment., Funding: National Eye Research Centre, Above and Beyond, and Moorfields Eye Charity., (Copyright © 2018 Elsevier Ltd.

Objective: To evaluate reproducibility (reliability and agreement) of the Brachial Assessment Tool (BrAT), a new patient-reported outcome measure for adults with traumatic brachial plexus injury (BPI)., Design: Prospective repeated-measure design., Setting: Outpatient clinics., Participants: Adults with confirmed traumatic BPI (N=43; age range, 19-82y)., Interventions: People with BPI completed the 31-item 4-response BrAT twice, 2 weeks apart. Results for the 3 subscales and summed score were compared at time 1 and time 2 to determine reliability, including systematic differences using paired t tests, test retest using intraclass correlation coefficient model 1,1 (ICC 1,1 ), and internal consistency using Cronbach α. Agreement parameters included standard error of measurement, minimal detectable change, and limits of agreement., Main Outcome Measure: BrAT., Results: Test-retest reliability was excellent (ICC 1,1 =.90-.97). Internal consistency was high (Cronbach α=.90-.98). Measurement error was relatively low (standard error of measurement range, 3.1-8.8). A change of >4 for subscale 1, >6 for subscale 2, >4 for subscale 3, and >10 for the summed score is indicative of change over and above measurement error. Limits of agreement ranged from ±4.4 (subscale 3) to 11.61 (summed score)., Conclusions: These findings support the use of the BrAT as a reproducible patient-reported outcome measure for adults with traumatic BPI with evidence of appropriate reliability and agreement for both individual and group comparisons. Further psychometric testing is required to establish the construct validity and responsiveness of the BrAT., (Copyright © 2017 American Congress of Rehabilitation Medicine.

Objective: To investigate the natural progression of olfactory impairment (OI) in individuals with traumatic brain injury (TBI) at 6 months postinjury., Participants: Forty-seven adults (mean age = 43.1 years, SD = 18.2), with predominantly severe TBI (mean posttraumatic amnesia [PTA] duration = 25.5 days, SD = 22.8)., Design: Consecutive admission longitudinal study., Main Measures: Participants were evaluated using the University of Pennsylvania Smell Identification Test (UPSIT) at resolution of PTA and at 6 months post-initial injury. Each participant was also interviewed to explore his or her experience of having an OI. Standard multiple regression was used to assess the ability of age, PTA duration, presence of facial fractures, and initial UPSIT score to predict olfactory performance at 6 months., Results: Thirty-five participants (74%) continued to demonstrate OI at 6 months. Thirty-two participants (68%) showed some improvement, but only 12 of these individuals achieved scores within the normal range. The remaining 15 participants either produced a poorer performance (23%) or demonstrated no change (9%). Initial UPSIT score uniquely accounted for 73.5% of the variance in UPSIT performance at 6 months., Conclusions: Olfactory impairment persists in a substantial proportion of adults who experience it post-TBI and has the potential to impact a broad spectrum of everyday activities.

Objective: To determine whether therapy influenced goal attainment following botulinum toxin (BoNT-A) injection for focal spasticity in adults with neurological conditions., Methods: A prospective observational cohort study conducted in a large metropolitan spasticity clinic on adults with focal spasticity of any origin. Participants were provided with a therapy programme, designed to maximise therapeutic outcome. The primary outcome measure was Goal Attainment Scaling. To measure adherence, participants completed a therapy-recording tool each day. Goal attainment, and the rate of adherence to the therapy programme, was evaluated after 10 weeks., Results: Active indications for BoNT-A treatment made up the majority of the goals (80.30%). Goals were achieved in 43/76 cases (56.60%; 95% CI = 42.40 to 69.80%). Therapy adherence was associated with significantly greater goal attainment (OR = 1.02, p = 0.03, 95% CI = 1.00 to 1.04). Greater adherence to therapy increased the odds of goal achievement for active indications but not for passive indications, suggesting a possible statistical interaction between the indication for injection and adherence to therapy (p < 0.01)., Conclusion: Therapy adherence was associated with greater goal attainment. Active indications for BoNT-A were more reliant on adherence to prescribed therapy programmes than passive indications, although further investigation is required.

Background: White matter disruptions in schizophrenia have been widely reported, but it remains unclear whether these abnormalities differ between illness stages. We mapped the connectome in patients with recently diagnosed and chronic schizophrenia and investigated the extent and overlap of white matter connectivity disruptions between these illness stages., Methods: Diffusion-weighted magnetic resonance images were acquired in recent-onset (n = 19) and chronic patients (n = 45) with schizophrenia, as well as age-matched controls (n = 87). Whole-brain fiber tracking was performed to quantify the strength of white matter connections. Connections were tested for significant streamline count reductions in recent-onset and chronic groups, relative to separate age-matched controls. Permutation tests were used to assess whether disrupted connections significantly overlapped between chronic and recent-onset patients. Linear regression was performed to test whether connectivity was strongest in controls, weakest in chronic patients, and midway between these extremities in recent-onset patients (controls > recent-onset > chronic)., Results: Compared with controls, chronic patients displayed a widespread network of connectivity disruptions (p < 0.01). In contrast, connectivity reductions were circumscribed to the anterior fibers of the corpus callosum in recent-onset patients (p < 0.01). A significant proportion of disrupted connections in recent-onset patients (86%) coincided with disrupted connections in chronic patients (p < 0.01). Linear regression revealed that chronic patients displayed reduced connectivity relative to controls, while recent-onset patients showed an intermediate reduction compared with chronic patients (p < 0.01)., Conclusions: Connectome pathology in recent-onset patients with schizophrenia is confined to select tracts within a more extensive network of white matter connectivity disruptions found in chronic illness. These findings may suggest a trajectory of progressive deterioration of connectivity in schizophrenia.

Purpose: Speech-language pathologists (SLPs) have a key role in supporting educational participation for secondary and tertiary students with traumatic brain injury (TBI). This article aims to (i) explore issues identified by students with TBI that affect educational participation beyond their academic performance, (ii) offer a framework based on research evidence to guide the practice of SLPs and (iii) explore strategies that may expand the traditional roles of SLPs to support students beyond academic performance., Method: Data were drawn from an earlier qualitative research project in which three adolescent males were interviewed about their experiences of returning to education after severe TBI. Interviews were recorded, transcribed verbatim and analysed using a grounded theory approach., Result: Six themes were identified that had a substantial impact beyond academic performance: poor community awareness of TBI, the invisible nature of TBI, getting back to everyday life, planning to return to education, being accepted and adjusting to long-term changes. Incorporating these factors, a clinical framework is put forward to guide SLPs in developing strategies for promoting positive educational participation., Conclusion: By considering factors beyond academic performance and addressing these in intervention, SLPs may significantly improve the overall educational success and wellbeing of students living with TBI.

We examined putative microglial activation as a function of illness course in schizophrenia. Microglial activity was quantified using [ 11 C](R)-(1-[2-chrorophynyl]-N-methyl-N-[1-methylpropyl]-3 isoquinoline carboxamide ( 11 C-(R)-PK11195) positron emission tomography (PET) in: (i) 10 individuals at ultra-high risk (UHR) of psychosis; (ii) 18 patients recently diagnosed with schizophrenia; (iii) 15 patients chronically ill with schizophrenia; and, (iv) 27 age-matched healthy controls. Regional-binding potential (BP ND ) was calculated using the simplified reference-tissue model with four alternative reference inputs. The UHR, recent-onset and chronic patient groups were compared to age-matched healthy control groups to examine between-group BP ND differences in 6 regions: dorsal frontal, orbital frontal, anterior cingulate, medial temporal, thalamus and insula. Correlation analysis tested for BP ND associations with gray matter volume, peripheral cytokines and clinical variables. The null hypothesis of equality in BP ND between patients (UHR, recent-onset and chronic) and respective healthy control groups (younger and older) was not rejected for any group comparison or region. Across all subjects, BP ND was positively correlated to age in the thalamus (r=0.43, P=0.008, false discovery rate). No correlations with regional gray matter, peripheral cytokine levels or clinical symptoms were detected. We therefore found no evidence of microglial activation in groups of individuals at high risk, recently diagnosed or chronically ill with schizophrenia. While the possibility of 11 C-(R)-PK11195-binding differences in certain patient subgroups remains, the patient cohorts in our study, who also displayed normal peripheral cytokine profiles, do not substantiate the assumption of microglial activation in schizophrenia as a regular and defining feature, as measured by 11 C-(R)-PK11195 BP ND .

Study Design: Longitudinal cohort design., Objectives: First, to explore the longitudinal outcomes for people who received early intervention vocational rehabilitation (EIVR); second, to examine the nature and extent of relationships between contextual factors and employment outcomes over time., Setting: Both inpatient and community-based clients of a Spinal Community Integration Service (SCIS)., Methods: People of workforce age undergoing inpatient rehabilitation for traumatic spinal cord injury were invited to participate in EIVR as part of SCIS. Data were collected at the following three time points: discharge and at 1 year and 2+ years post discharge. Measures included the spinal cord independence measure, hospital anxiety and depression scale, impact on participation and autonomy scale, numerical pain-rating scale and personal wellbeing index. A range of chi square, correlation and regression tests were undertaken to look for relationships between employment outcomes and demographic, emotional and physical characteristics., Results: Ninety-seven participants were recruited and 60 were available at the final time point where 33% (95% confidence interval (CI): 24-42%) had achieved an employment outcome. Greater social participation was strongly correlated with wellbeing (ρ=0.692), and reduced anxiety (ρ=-0.522), depression (ρ=-0.643) and pain (ρ=-0.427) at the final time point. In a generalised linear mixed effect model, education status, relationship status and subjective wellbeing increased significantly the odds of being employed at the final time point. Tertiary education prior to injury was associated with eight times increased odds of being in employment at the final time point; being in a relationship at the time of injury was associated with increased odds of being in employment of more than 3.5; subjective wellbeing, while being the least powerful predictor was still associated with increased odds (1.8 times) of being employed at the final time point., Conclusions: EIVR shows promise in delivering similar return-to-work rates as those traditionally reported, but sooner. The dynamics around relationships, subjective wellbeing, social participation and employment outcomes require further exploration.

Introduction: Moderate to severe traumatic brain injury (TBI) can result in development of spasticity, which adversely affects function and quality of life. Given the foundation of optimal clinical practice is use of the best available evidence, we aimed to identify, describe, and evaluate methodological quality of evidence-based spasticity clinical practice guidelines (CPGs)., Methods: A comprehensive search for CPGs encompassed electronic databases and online sources. Eligible CPGs were evaluated using the validated Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument., Results: Five CPGs were eligible for review; 2 were specific to acquired brain injury and 1 to TBI. The 3 brain injury-specific CPGs contained 423 recommendations overall, but only 8 spasticity recommendations. On the basis of AGREE appraisals, all CPGs performed well in the areas of reporting scope and purpose; clearly presenting recommendations; including various stakeholders in the CPG development process; and reporting conflict of interest. However, only one CPG performed adequately on describing facilitators and barriers to implementation, advice, and tools on how to implement recommendations and provision of audit criteria. Intraclass correlation coefficient (ICC) for agreement between raters showed high agreement (ICC > 0.80) for most guidelines., Conclusion: Given the unique etiological features and treatment challenges associated with managing spasticity after TBI, more TBI-specific spasticity CPGs are required. These should incorporate information on the facilitators and barriers to implementation, advice on implementing recommendations, and audit criteria.

Background: Olfactory impairment (OI) can present in up to 66% of all individuals following traumatic brain injury (TBI) and can have significant implications for everyday life., Objective: To investigate the predictive factors, natural progression and consequences of OI following TBI in individuals 12 months post injury., Methods: In this prospective longitudinal study, 37 adults (28 males, 9 females), mean age 42.3 years (SD 19.4), with predominately severe TBI (mean length of posttraumatic amnesia (PTA) 28.6 days, SD 22.6) were assessed using the University of Pennsylvania Smell Identification Test (UPSIT). Each participant also participated in an open ended interview to allow exploration of their experience of having OI., Results: Thirty (83.33%) of the participants demonstrated persisting OI at 12 months. Nineteen of these participants demonstrated no change in their OI severity category and 4 produced a poorer performance. Thirteen participants (36.11%) demonstrated some recovery with 6 of these performing within the 'normal' range for age andgender., Conclusions: OI is an enduring impairment for a substantial proportion of individuals who experience it following severe TBI. It impacts a range of everyday activities, regardless of its severity, and requires comprehensive management during rehabilitation.

Objective: The aim of this systematic review was to establish the ecological validity of clinical tests of lower limb spasticity by determining whether the range of motion (ROM) and speed of limb movement during the assessment accurately replicate muscle function and joint biomechanics during walking., Methods: An electronic search of ten databases was performed to identify all relevant articles. The reference lists of all included articles were also searched. Identification of relevant articles, data extraction and quality assessment were performed independently by two reviewers., Results: Seventeen studies were included in the review. The Modified Ashworth Scale was the most commonly used clinical measure of lower limb spasticity. The ROM and speed of assessment were poorly reported for clinical scales of lower limb spasticity, making it difficult to draw conclusions regarding the relevance of these scales to walking performance., Conclusions: The ecological validity of the clinical scales of spasticity could not be determined as studies did not adequately report their testing procedure. Further research into the ecological validity of clinical scales of spasticity is required in order to better understand the impact that spasticity has on functional activities such as walking.

Primary Objectives: The main aim of this study was to determine whether the presence of distal lower-limb spasticity had a greater impact on mobility for those who had greater levels of muscle paresis following traumatic brain injury (TBI)., Research Design: This was a cross-sectional cohort study of convenience. Seventy-five people attending physiotherapy for mobility limitations following TBI participated in this study. All participants had sustained a moderate-severe TBI and were grouped according to the presence or absence of ankle plantarflexor spasticity for comparison., Main Outcomes and Results: The primary outcome measure for mobility was self-selected walking speed and the primary outcome measure for muscle strength was hand-held dynamometry. Secondary outcome measures for mobility and muscle strength were the High-level Mobility Assessment Tool (HiMAT) and ankle power generation (APG) at push-off. Spasticity was quantified with the Modified Tardieu scale. Participants with ankle plantarflexor spasticity (Group 2) had slower self-selected walking speeds. There was no statistically significant effect for Group and plantarflexor strength (p = 0.81)., Conclusion: Although participants with ankle plantarflexor spasticity walked significantly slower than those without, the presence of ankle plantarflexor spasticity did not lead to greater mobility limitations for those who were weak.

Objective: To evaluate the internal construct validity and dimensionality of a new patient-reported outcome measure for people with traumatic brachial plexus injury (BPI) based on the International Classification of Functioning, Disability and Health definition of activity., Design: Cross-sectional study., Setting: Outpatient clinics., Participants: Adults (age range, 18-82y) with a traumatic BPI (N=106)., Interventions: There were 106 people with BPI who completed a 51-item 5-response questionnaire. Responses were analyzed in 4 phases (missing responses, item correlations, exploratory factor analysis, and Rasch analysis) to evaluate the properties of fit to the Rasch model, threshold response, local dependency, dimensionality, differential item functioning, and targeting., Main Outcome Measures: Not applicable, as this study addresses the development of an outcome measure., Results: Six items were deleted for missing responses, and 10 were deleted for high interitem correlations >.81. The remaining 35 items, while demonstrating fit to the Rasch model, showed evidence of local dependency and multidimensionality. Items were divided into 3 subscales: dressing and grooming (8 items), arm and hand (17 items), and no hand (6 items). All 3 subscales demonstrated fit to the model with no local dependency, minimal disordered thresholds, no unidimensionality or differential item functioning for age, time postinjury, or self-selected dominance. Subscales were combined into 3 subtests and demonstrated fit to the model, no misfit, and unidimensionality, allowing calculation of a summary score., Conclusions: This preliminary analysis supports the internal construct validity of the Brachial Assessment Tool, a unidimensional targeted 4-response patient-reported outcome measure designed to solely assess activity after traumatic BPI regardless of level of injury, age at recruitment, premorbid limb dominance, and time postinjury. Further examination is required to determine test-retest reliability and responsiveness., (Copyright © 2016 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

Introduction: Traumatic brain injury is the leading cause of disability in young adults aged 15 to 45 years. Mobility limitations are prevalent, and range in severity from interfering with basic day-to-day tasks to restricting participation in higher level social, leisure, employment and sporting activities. Despite the prevalence and severity of physical impairments, such as poor balance and spasticity, the main contributor to mobility limitations following traumatic brain injury is low muscle power generation. Strengthening exercises that are performed quickly are termed 'ballistic' as they are aimed at improving the rate of force production and, hence, muscle power. This is compared with conventional strength training, which is performed slowly and aims to improve maximum force production, yet has limited impact on mobility., Research Question: In people recovering from traumatic brain injury: (1) is a 12-week ballistic strength-training program targeting the three muscle groups critical for walking more effective than usual care at improving mobility, strength and balance; and (2) does improved mobility translate to better health-related quality of life?, Design: A prospective, multi-centre, randomised, single-blind trial with concealed allocation will be conducted., Participants and Setting: Participants will be patients with a neurologically based movement disorder affecting mobility as a result of traumatic brain injury. Patients will be recruited during the acute phase of rehabilitation (n=166), from brain injury units in large metropolitan hospitals in Melbourne and Sydney, Australia., Intervention: For 12 weeks, participants in the experimental group will have three 60-minute sessions of usual physiotherapy intervention replaced by three 60-minute sessions of strength training (ballistic strength, gait). The three key muscle groups responsible for forward propulsion will be targeted: ankle plantarflexors, hip flexors and the hip extensors. Initial loads will be low, to facilitate high contraction velocities. Progression to higher loads will occur only if participants can perform the exercises ballistically. The control group will have their three 60-minute sessions of usual physiotherapy intervention (balance, strength, stretch, cardiovascular fitness, gait) standardised so that all participants have equivalent therapy time. Both groups will continue to receive usual rehabilitation., Outcome Measures: The primary outcome will be mobility, measured using the High Level Mobility Assessment Tool. The secondary outcomes will be walking speed, muscle strength, balance and health-related quality of life. Walking speed will be measured using the 10-m walking test. Strength will be measured by a 6 repetition maximum, seated, single leg press test. Balance will be measured as the single limb support time. Health-related quality of life will be measured using the Assessment of Quality of Life. Outcomes will be measured at baseline (0 months), at completion of the intervention phase (3 months), and 3 months after cessation of intervention (6 months). Baseline measures will be completed prior to randomisation. Assessors blinded to group allocation will perform all measures., Analysis: Baseline characteristics of participants will be determined according to group, using descriptive statistics. The proportion of patients compliant with the intervention will be calculated according to group and compared using Fisher's exact test. Compliance with the intervention will be defined as those who have satisfactorily completed at least 80% of the allocated sessions (29 of 36 sessions). The between-group difference for all outcomes will be estimated using analysis of covariance, adjusting for baseline High Level Mobility Assessment Tool score, age, gender and length of post-traumatic amnesia. Analyses will be conducted on an intention-to-treat basis., Discussion: Strength training in neurological rehabilitation is highly topical because muscle weakness has been identified as the primary impairment leading to mobility limitations in many neurological populations. This project represents the first international study of ballistic strength training after traumatic brain injury. The novelty of ballistic strength training is that the exercises attempt to replicate how lower limb muscles work, by targeting the high angular velocities attained during walking and higher level activities., (Copyright © 2016 Australian Physiotherapy Association.

Objective: The main aim of this project was to determine the impact of plantarflexor spasticity on muscle performance for ambulant people with traumatic brain injury (TBI)., Setting: A large metropolitan rehabilitation hospital., Participants: Seventy-two ambulant people with TBI who were attending physiotherapy for mobility limitations. Twenty-four participants returned for a 6-month follow-up reassessment., Design: Cross-sectional cohort study., Main Measures: Self-selected walking speed, Tardieu scale, ankle plantarflexor strength, and ankle power generation (APG)., Results: Participants with ankle plantarflexor spasticity had significantly lower self-selected walking speed; however, there was no significant difference in ankle plantarflexor strength or APG. Participants with ankle plantarflexor spasticity were not restricted in the recovery of self-selected walking speed, ankle plantarflexor strength, or APG, indicating equivalent ability to improve their mobility over time despite the presence of spasticity., Conclusion: Following TBI, people with ankle plantarflexor spasticity have significantly greater mobility limitations than those without spasticity, yet retain the capacity for recovery of self-selected walking speed, ankle plantarflexor strength, and APG.

Objective: To examine the association between lower limb spasticity and mobility limitations following traumatic brain injury (TBI) and determine the influence of spasticity distribution on mobility outcomes following TBI., Setting: A large metropolitan rehabilitation hospital., Participants: Ninety-three ambulant people with TBI who were attending physiotherapy for mobility limitations., Design: Cross-sectional cohort study., Main Measures: The High-Level Mobility Assessment Tool, gait velocity, and the Tardieu scale., Results: Lower limb spasticity was common following TBI, with a distal distribution being the most prevalent. Participants with spasticity had significantly greater initial mobility limitations than participants without spasticity. However, the distribution of lower limb spasticity and the presence of unilateral or bilateral spasticity had no additional impact on mobility outcomes. There was no significant difference in mobility outcomes at the 6-month follow-up for people with spasticity, indicating that individuals have equivalent ability to improve their mobility over time despite the presence of spasticity., Conclusion: Following TBI, people with lower limb spasticity have significantly greater mobility limitations than those without spasticity, yet the presence and distribution of spasticity does not appear to impact mobility outcomes. There is long-term potential to improve mobility despite the presence of spasticity.

Primary Objectives: To determine whether the severity of lower limb spasticity had a differential effect on mobility following traumatic brain injury (TBI) and to investigate whether the distribution of lower limb spasticity influenced compensation strategies when walking., Research Design: Ninety-three people attending physiotherapy for mobility limitations following TBI participated in this study. Participants were grouped according to the presence and distribution of lower limb spasticity for comparison., Main Outcomes and Results: Mobility was measured using a 10-metre walk test and the high level mobility assessment tool. Three dimensional gait analysis was used to measure power generation and spasticity was assessed using the Tardieu scale. No significant relationship was found between the severity of lower limb spasticity and mobility limitations. There was a strong relationship between ankle power generation and mobility performance. Proximal compensation strategies did not vary significantly between groups with different distributions of lower limb spasticity., Conclusion: The ability to generate ankle power has a large impact on mobility outcome following TBI. Although spasticity was prevalent, the severity and distribution did not appear to impact mobility outcomes. Proximal compensation strategies were not influenced by the distribution of lower limb spasticity following TBI.

Background: The majority of strokes, both ischaemic and haemorrhagic, are attributable to a relatively small number of risk factors which are readily manageable in primary care setting. Implementation of best-practice recommendations for risk factor management is calculated to reduce stroke recurrence by around 80%. However, risk factor management in stroke survivors has generally been poor at primary care level. A model of care that supports long-term effective risk factor management is needed., Aim: To determine whether the model of Integrated Care for the Reduction of Recurrent Stroke (ICARUSS) will, through promotion of implementation of best-practice recommendations for risk factor management reduce the combined incidence of stroke, myocardial infarction and vascular death in patients with recent stroke or transient ischaemic attack (TIA) of the brain or eye., Design: A prospective, Australian, multicentre, randomized controlled trial., Setting: Academic stroke units in Melbourne, Perth and the John Hunter Hospital, New South Wales., Subjects: 1000 stroke survivors recruited as from March 2007 with a recent (<3 months) stroke (ischaemic or haemorrhagic) or a TIA (brain or eye)., Randomization: Randomization and data collection are performed by means of a central computer generated telephone system (IVRS)., Intervention: Exposure to the ICARUSS model of integrated care or usual care., Primary Outcome: The composite of stroke, MI or death from any vascular cause, whichever occurs first., Secondary Outcomes: Risk factor management in the community, depression, quality of life, disability and dementia., Statistical Power: With 1000 patients followed up for a median of one-year, with a recurrence rate of 7-10% per year in patients exposed to usual care, the study will have at least 80% power to detect a significant reduction in primary end-points, Conclusion: The ICARUSS study aims to recruit and follow up patients between 2007 and 2013 and demonstrate the effectiveness of exposure to the ICARUSS model in stroke survivors to reduce recurrent stroke or vascular events and promote the implementation of best practice risk factor management at primary care level., (© 2015 World Stroke Organization.)

Objectives: To assess the efficacy of cognitive existential couple therapy (CECT) for relationship function, coping, cancer distress and mental health in men with localised prostate cancer and in their partners., Patients Subjects and Methods: A randomised controlled trial was conducted with 62 couples randomly assigned to the six-session CECT programme or care as usual. The couple's relationship function (primary outcome), and coping, cancer distress and mental health (secondary outcomes) were evaluated at T0 (baseline), T1 (after treatment) and T2 (9 months from T0). A repeated-measures analysis of covariance model, which incorporated T0 measurements as a covariate, was used to compare treatment groups at T1 and T2., Results: After CECT, patients reported significantly greater use of adaptive coping (P = 0.03) and problem-focused coping (P = 0.01). These gains were maintained at follow-up, while relationship cohesion had improved (P = 0.03), as had relationship function for younger patients (P = 0.01). Younger partners reported less cancer-specific distress (P = 0.008), avoidance (P = 0.04), intrusive thought (P = 0.006), and hyperarousal (P = 0.01). Gains were maintained at follow-up, while relationship cohesion (P = 0.007), conflict resolution (P = 0.01) and relational function (P = 0.009) all improved., Conclusion: CECT resulted in improved coping for patients and lower cancer-distress for partners. Maintained over time this manifests as improved relationship function. CECT was acceptable to couples, alleviated long-term relationship decline, and is therefore suitable as a preventative mental health intervention for couples facing prostate cancer. Given resourcing demands, we recommend dissemination of CECT be targeted at younger couples, as CECT was more acceptable to the younger group, and they derived greater benefit from it., (© 2015 The Authors.

Objective: To determine the independent effectiveness of adjunctive therapies when provided in conjunction with botulinum neurotoxin (BoNT-A) injection for focal spasticity in adults with neurological conditions., Data Sources: Nine electronic databases., Study Selection: A systematic search was performed to identify randomized, controlled trials (RCTs) evaluating the benefit of adjunctive therapies following BoNT-A injection., Data Extraction/synthesis: Two authors extracted the data independently. Each trial was assessed for internal validity and rated for quality using the PEDro scale. Articles were further appraised using the American Academy of Neurology (AAN) evidence classification to construct concise clinical recommendations., Results: The search identified 12 studies that reported on the effects of eight different adjunctive therapies following BoNT-A injection in adults with focal spasticity. No high level evidence was identified. The mean PEDro score for the 12 studies was 5.6 (SD = 1.6) and the clinical recommendations provided were Grade U, indicating the effectiveness of the adjunctive therapies was unknown or unproven., Conclusion: There was insufficient evidence to support or refute the effectiveness of any of the commonly prescribed adjunctive therapies following BoNT-A injection for focal spasticity in adults.

Severe traumatic brain injury (TBI) in older age is associated with high rates of mortality. However, little is known about outcome following mild TBI (mTBI) in older age. We report on a prospective cohort study investigating 3 month outcome in older age patients admitted to hospital-based trauma services. First, 50 mTBI older age patients and 58 orthopedic controls were compared to 123 community control participants to evaluate predisposition and general trauma effects on cognition. Specific brain injury effects were subsequently evaluated by comparing the orthopedic control and mTBI groups. Both trauma groups had significantly lower performances than the community group on prospective memory (d=0.82 to 1.18), attention set-shifting (d=-0.61 to -0.69), and physical quality of life measures (d=0.67 to 0.84). However, there was only a small to moderate but non-significant difference in the orthopedic control and mTBI group performances on the most demanding task of prospective memory (d=0.37). These findings indicate that, at 3 months following mTBI, older adults are at risk of poor cognitive performance but this is substantially accounted for by predisposition to injury or general multi-system trauma.

This paper reports on recent changes and future plans concerning the International Society of Physical and Rehabilitation Medicine. Issues discussed are its structural organization, collaboration and recognition, liaison with the World Health Organization , work in strengthening science, and its future agenda.

The International Society for Physical and Rehabilitation Medicine has recognized the World Report on Disability as a guide for its future activities and endorsed its responsibility to disseminate, to analyze, and to implement the report's recommendations. The activities of the International Society for Physical and Rehabilitation Medicine on the global stage are embedded in a strategy that includes national and regional associations. This article reports on recent and forthcoming activities of the International Society for Physical and Rehabilitation Medicine regarding the World Report on Disability and identifies five major challenges that will impact future International Society for Physical and Rehabilitation Medicine activities. These challenges relate to (1) education and training, (2) the support of strong role models, (3) disaster management, (4) the development of innovative rehabilitation services, and (5) rehabilitation research.

The deleterious consequences of traumatic brain injury (TBI) impair capacity to return to many avenues of pre-morbid life. However, there has been limited longitudinal research examining outcome beyond five years post-injury. The aim of this study was to examine aspects of function, previously shown to be affected following TBI, over a span of 10 years. One hundred and forty one patients with TBI were assessed at two, five, and 10 years post-injury using the Structured Outcome Questionnaire. Fatigue and balance problems were the most common neurological symptoms, with reported rates decreasing only slightly during the 10-year period. Mobility outcomes were good in more than 75% of patients, with few participants requiring aids for mobility. Changes in cognitive, communication, behavioral, and emotional functions were reported by approximately 60% of the sample at all time points. Levels of independence in activities of daily living were high during the 10-year period, and as many as 70% of subjects returned to driving. Nevertheless, approximately 40% of patients required more support than before their injury. Only half the sample returned to previous leisure activities and fewer than half were employed at each assessment time post-injury. Although marital status remained stable over time, approximately 30% of participants reported difficulties in personal relationships. Older age at injury did not substantially alter the pattern of changes over time, except in employment. Overall, problems that were evident at two years post-injury persisted until 10 years post-injury. The importance of these findings is discussed with reference to rehabilitation programs.

Background: Brain tumours can cause significant disability, which may be amenable to multidisciplinary rehabilitation. However, the evidence base for this is unclear., Objectives: To assess the effectiveness of multidisciplinary rehabilitation in adults after primary brain tumour treatment, especially the types of approaches that are effective (settings, intensity) and the outcomes that are affected., Search Methods: We searched the Cochrane Neuromuscular Disease Group Specialized Register (March week 2, 2012), The Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library Issue 3, 2012), MEDLINE (1966 to March week 2, 2012), EMBASE (1980 to March week 2, 2012), PEDro (1982 to March 2012) and LILACS (1982 to March week 2, 2012). We checked the bibliographies of papers identified and contacted the authors and known experts in the field to seek published and unpublished trials., Selection Criteria: Controlled clinical trials (randomised and non-randomised clinical trials) that compared multidisciplinary rehabilitation in primary brain tumour with either routinely available local services or lower levels of intervention, or studies that compared multidisciplinary rehabilitation in different settings or at different levels of intensity., Data Collection and Analysis: Three review authors independently assessed study quality, extracted data and performed a 'best evidence' synthesis based on methodological quality., Main Results: No randomised controlled trials (RCTs) or controlled clinical trials (CCTs) were identified., Authors' Conclusions: No RCTs or CCTs were available for synthesis of 'best evidence' for multidisciplinary rehabilitation after treatment for brain tumour patients. However, this does not suggest the ineffectiveness of multidisciplinary rehabilitation but rather highlights the challenges in trial design and rigour, outcome measurement and complexities of care in this population. For completeness of literature, 12 observational studies (with high risk of bias) involving patients with brain tumours were included. These studies provided 'very low level' evidence suggesting that multidisciplinary rehabilitation (inpatient, home-based) may improve functional outcomes, and ambulatory programmes (outpatient and home-based) may improve vocation and quality of life. These conclusions are tentative at best, given gaps in current research in this area. Further research is needed into appropriate and robust study designs, outcome measurement, caregiver needs, evaluation of optimal settings, type, intensity, duration of therapy, and cost-effectiveness of multidisciplinary rehabilitation in the brain tumour population.
