IntroductionFalls are a concern for wheelchair users with spinal cord injury (SCI). Falls can negatively impact the physical and psychological well-being of fallers. To date, the perspectives of wheelchair users with lived experiences of SCI on the contributors to falls has been understudied. Information about factors that influence fall risk would guide the development of effective fall prevention strategies.ObjectivesTo gain a comprehensive understanding of the factors that influenced the risk of falling as perceived by wheelchair users with SCI.DesignA qualitative study using photo-elicitation interviews.SettingA Canadian SCI rehabilitation hospital and the participants’ home/community environments.ParticipantsTwelve wheelchair users living in the community with chronic SCI.MethodsParticipants captured photographs of situations, places or things that they perceived increased and decreased their risk of falling. Semistructured photo-elicitation interviews were conducted to discuss the content of the photographs and explore perceptions of fall risk factors. A hybrid thematic analysis and the Biological, Behavioural, Social, Economic, and Environmental model were used as a framework to organise/synthesise the data.ResultsOverall, the findings indicated that the risk of falling was individualised, complex and dynamic to each person’s life situation. Four main themes were revealed in our analysis: (1) Falls and fall risk caused by multiple interacting factors; (2) Dynamic nature of fall risk; (3) Single factors were targeted to reduce falls and fall-related injuries; and (4) Fall prevention experiences and priorities.ConclusionsEach wheelchair user encountered numerous fall risk factors in their everyday lives. Information from this study can be used to set priorities for fall prevention. Fall prevention initiatives should consider a wheelchair user’s fall risks in a holistic manner, acknowledging that a person’s current situation, as well as anticipating their fall risks and fall prevention needs, will change over time.

IntroductionWheelchair users with spinal cord injury are at a high risk of falls. However, the perspectives of wheelchair users with spinal cord injury on their fall circumstances and their preferences for fall prevention strategies/interventions remain understudied. Therefore, we aimed to: a) describe the circumstances of falls experienced by wheelchair users with spinal cord injury over a six-month period, b) explore their perspectives of why falls occurred in certain situations, and c) explore their perspectives on recommended content/structure of fall prevention strategies/interventions.MethodsThis sequential explanatory mixed methods study had two phases. Phase I involved tracking of falls experienced by wheelchair users with spinal cord injury over six months, in which participants completed a survey after experiencing a fall to track the number/circumstance of each fall. Data from the surveys were descriptively reported. Phase II involved a photovoice focus group discussion of the survey findings and their preferences for fall prevention strategies/interventions. Data from the focus group discussion were analyzed using a thematic analysis.ResultsThirty-two participants completed phase I. More than half of the participants fell at least once in six months. Falls commonly occurred in the afternoon during a transfer, or when participants were wheeling over uneven ground. One-third of the falls caused an injury. Eleven participants that fell during phase I participated in the focus group. Two main themes were identified from the discussion: 1) "circumstances surrounding the falls" (e.g. when falls occurred, the home is a 'safe space') and 2) "suggestions and preferences for fall prevention strategies/interventions" (e.g. fall prevention involves all, fall prevention training available as needed).ConclusionFall prevention strategies/interventions should be an integral component of rehabilitation practices across the lifespan. Participants recommend customizing fall prevention strategies/interventions to their specific needs to guide the structure, content, and delivery of targeted fall prevention programs.

OBJECTIVE: To identify a set of essential components for primary care for patients with spinal cord injury (SCI) for inclusion in a point-of-practice toolkit for primary care practitioners (PCP) and identification of the essential elements of SCI care that are required in primary care and those that should be the focus of specialist care. DESIGN: Modified Delphi consensus process; survey methodology. SETTING: Primary care. PARTICIPANTS: Three family physicians, six specialist physicians, and five inter-disciplinary health professionals completed surveys. OUTCOME MEASURES: Importance of care elements for inclusion in the toolkit (9-point scale: 1 = lowest level of importance, 9 = greatest level of importance) and identification of most responsible physician (family physician, specialist) for completing key categories of care. Open-ended comments were solicited. RESULTS: There was consensus between the respondent groups on the level of importance of various care elements. Mean importance scores were highest for autonomic dysreflexia, pain, and skin care and lowest for preventive care, social issues, and vital signs. Although, there was agreement across all respondents that family physicians should assume responsibility for assessing mental health, there was variability in who should be responsible for other care categories. Comments were related to the need for shared care approaches and capacity building and lack of knowledge and specialized equipment as barriers to optimal care. CONCLUSION: This study identified important components of SCI care to be included in a point-of-practice toolkit to facilitate primary care for persons with SCI.

Objective To analyze relations among injury, demographic, and environmental factors on function, health-related quality of life (HRQoL), and life satisfaction in individuals with traumatic spinal cord injury (SCI). Design Prospective observational registry cohort study. Setting Specialized acute and rehabilitation SCI centers. Participants Participants (N=340) from the Rick Hansen Spinal Cord Injury Registry (RHSCIR) who were prospectively recruited from 2004 to 2014 were included. The model cohort participants were 79.1% men, with a mean age of 41.6±17.3 years. Of the participants, 34.7% were motor/sensory complete (ASIA Impairment Scale [AIS] grade A). Interventions None. Main Outcome Measures Path analysis was used to determine relations among SCI severity (AIS grade and anatomic level [cervical/thoracolumbar]), age at injury, education, number of health conditions, functional independence (FIM motor score), HRQoL (Medical Outcomes Study 36-Item Short-Form Health Survey [Version 2] Physical Component Score [PCS] and Mental Component Score [MCS]), and life satisfaction (Life Satisfaction-11 [LiSat-11]). Model fit was assessed using recommended published indices. Results Goodness of fit of the model was supported by all indices, indicating the model results closely matched the RHSCIR data. Higher age, higher severity injuries, cervical injuries, and more health conditions negatively affected FIM motor score, whereas employment had a positive effect. Higher age, less education, more severe injuries (AIS grades A–C), and more health conditions negatively correlated with PCS (worse physical health). More health conditions were negatively correlated with a lower MCS (worse mental health), however were positively associated with reduced function. Being married and having higher function positively affected Lisat-11, but more health conditions had a negative effect. Conclusions Complex interactions and enduring effects of health conditions after SCI have a negative effect on function, HRQoL, and life satisfaction. Modeling relations among these types of concepts will inform clinicians how to positively effect outcomes after SCI (eg, development of screening tools and protocols for managing individuals with traumatic SCI who have multiple health conditions).

Increased visceral adiposity places individuals with chronic spinal cord injury (SCI) at increased risk of cardiometabolic disease. The purpose of this study was to identify if people with chronic SCI who participate in any moderate- to vigorous-intensity leisure time physical activity (LTPA) have lower visceral adipose tissue (VAT) area compared with those who report none. Participants included 136 adult men (n = 100) and women (n = 36) with chronic (mean (±SD) 15.6 ± 11.3 years post-injury) tetraplegia (n = 66) or paraplegia (n = 70) recruited from a tertiary rehabilitation hospital. VAT area was assessed via whole-body dual-energy X-ray absorptiometry using a Hologic densitometer and the manufacturer’s body composition software. Moderate-to-vigorous LTPA was assessed using the Leisure Time Physical Activity Questionnaire for People with SCI (LTPAQ-SCI) or the Physical Activity Recall Assessment for People with SCI (PARA-SCI). Summary scores were dichotomized into any or no participation in moderate-to-vigorous LTPA to best represent the intensity described in current population-specific physical-activity guidelines. Data were analyzed using univariate and multiple regression analyses to identify the determinants of VAT. Overall, the model explained 67% of the variance in VAT area and included time post-injury, age-at-injury, android/gynoid ratio, waist circumference, and moderate-to-vigorous LTPA. Participation in any moderate-to-vigorous LTPA was significantly (95% confidence interval: –34.71 to –2.61, p = 0.02) associated with VAT after controlling for injury-related and body-composition correlates. Moderate-to-vigorous LTPA appears to be related to lower VAT area, suggesting potential for LTPA to reduce cardiometabolic disease risk among individuals with chronic SCI.

Background: Although cardiac autonomic dysfunction is a contributing factor for cardiovascular disease development in individuals with a spinal cord injury (SCI), it remains poorly understood. Heart rate variability (HRV) analysis has the potential to non-invasively assess the cardiac autonomic nervous system. The study objectives are (a) to determine if there are differences in HRV measures across neurological level of impairment (NLI) and American Spinal Cord Injury Association Impairment Scale (AIS) subgroups, and (b) to determine if there is a relationship between HRV frequency measures (low frequency [LF] and high frequency [HF]) at rest. Methods: We conducted a secondary data analysis of a primary data set from a published cross-sectional study of electrocardiogram recordings of 56 subjects (44 men and 12 women, mean age ± SD = 46.75 ± 12.44 years) with a chronic traumatic SCI (C1-T12, AIS A-D, ≥2 years post injury). HRV was analyzed using time and frequency domain measures. Results: There were no significant HRV differences across NLI and AIS subgroups. The LF and HF indices were positively correlated in the entire sample (r = 0.708, p < .0001) and among impairment subgroups. Conclusion: No differences were observed in the HRV time and frequency measures when compared across NLI and AIS subgroups. The results were considered inconclusive, since possible explanations include inadequate sample size as well as other physiological considerations. A positive correlation was found between LF and HF when assessed at rest. The relationship between LF and HF may not necessarily represent a rebalanced autonomic nervous system, but it does question the utility of solely measuring LF:HF at rest in persons with chronic SCI.

Background: There is a paucity of studies using administrative health data to examine the epidemiology, health care utilization, and outcomes for non-traumatic spinal cord dysfunction (NTSCD). Objective: The purpose of this study is to characterize discrete NTSCD cohorts using decision algorithms with Canadian health administrative databases. Method: Data were provided by the Canadian Institute for Health Information that included all acute care hospital, day surgery, ambulatory, and inpatient rehabilitation records of patients with neurological impairment between April 1, 2004 and March 31, 2011. Diagnostic codes for neurological impairment and NTSCD etiology were used to identify cases and classify 3 NTSCD groups (most likely, probable, and possible). Logistic regression identified factors related to inpatient rehabilitation admission within 7 days of discharge among the preferred group. Results: The most likely NTSCD group (n = 6,362) was significantly older and had a greater proportion of women and individuals with cauda equina lesions compared to the other 2 NTSCD groups (probable [n = 2,777] and possible [n = 11,179]; ps < .001). Factors associated with the likelihood of an inpatient rehabilitation admission included being older (odds ratio [OR], 1.01; 95% CI, 1.00–1.01), being female (OR, 1.18; 95% CI, 1.06–1.32), having paraplegia diagnosis compared to cauda equina (OR, 1.24; 95% CI, 1.09–1.41), residing in an urban area compared to a rural area (OR, 1.34; 95% CI, 1.13–1.58), having degenerative etiology compared to other (OR, 1.59; 95% CI, 1.41–1.80), and having an MRI on record compared to not (OR = 1.57; 95% CI, 1.39–1.76). Conclusion: Administrative data allow for ongoing surveillance of a population in a relatively cost-effective manner. Advancing our knowledge of NTSCD epidemiology, health outcomes, and system performance can inform policy and system planning.

To determine the efficacy of functional electrical stimulation therapy assisted walking (FES-T) compared to a conventional aerobic and resistance training (CONV) with respect to bone biomarkers and lower extremity bone strength outcomes among adults with chronic motor incomplete spinal cord injury (SCI).Parallel group randomized controlled trial ( www.clinicaltrials.gov - NCT0020196819). Site: Tertiary academic rehabilitation centre in Canada.Adults with chronic (≥18 months) motor incomplete SCI (C2-T12 AIS C-D) were consented and randomized to FES-T or CONV training for 45 minutes thrice-weekly for 4 months. Osteocalcin (OC), β-cross laps (CTX) and sclerostin were assessed at baseline, and 4 months. Similarly, total hip, distal femur and proximal tibia region bone mineral density (BMD) via DXA (4500A, Hologic Inc. Waltham, MA, USA) and tibia bone quality via pQCT (Stratec XCT-2000, Mezintecknik, Pforzheim, Germany) were assessed at baseline, 4, and 12 months. Between group differences were analyzed using repeated measures general linear models.Thirty-four participants (17 FES-T, 17 CONV) consented and were randomized, 27 participants completed the 4-month intervention and 12-month outcome assessments. Participants in the FES-T arm had a decrease in CTX and a significant increase in OC at intervention completion (P0.05). Significant biomarker changes were not observed in the CONV group. No within or between group differences from baseline were observed in sclerostin or bone strength.Four months of FES-T improved bone turnover (increase in OC and decrease in CTX) but not bone strength among individuals with chronic SCI. Future, long term FES-T may augment lower extremity bone strength.

Individuals with chronic spinal cord injury (SCI) are susceptible to central and visceral obesity and it's metabolic consequences; consensus based guidelines for obesity management after SCI have not yet been stablished.To identify and compare effective means of obesity management among SCI individuals.This systematic review included English and non-English articles, published prior to April 2017 found in the PubMed/Medline, Embase, CINAHL Psychinfo and Cochrane databases. Studies evaluating any obesity management strategy, alone or in combination, including: diet therapy, voluntary and involuntary exercise such as neuro-muscular electric stimulation (NMES), pharmacotherapy, and surgery, among individuals with chronic SCI were included. Outcomes of interest were reductions in waist circumference, body weight (BW), body mass index (BMI) and total fat mass (TFM) and increases in total lean body mass (TLBM) from baseline. From 3,553 retrieved titles and abstracts, 34 articles underwent full text review and 23 articles were selected for data abstraction. Articles describing weight loss due to inflammation, cancer or B12 deficiency were excluded. The Downs and Black reported poor to moderate quality of the studies.Bariatric surgery produced the greatest permanent weight reduction and BMI correction followed by combinations of physical exercise and diet therapy. Generally, NMES and pharmacotherapy improved TLBM and reduced TFM but not weight.The greatest weight reduction and BMI correction was produced by bariatric surgery, followed by a combination of physical exercise and diet therapy. NMES and pharmacologic treatment did not reduce weight or TFM but increased in TLBM.

Information on health-care utilization and the economic burden of disease are essential to understanding service demands, service accessibility, and practice patterns. This information may also be used to enhance the quality of care through altered resource allocation. Thus, a systematic review of literature on the economic impact of caring for SCI/D veterans would be of great value.To systematically review and critically appraise the literature on the economics of the management of veterans with SCI/D.Medline, EMBASE and PsycINFO databases were searched for articles on economic impact of management of SCI/D veterans, published from 1946 to September/2016. The STROBE statement was used to determine publication quality.The search identified 1,573 publications of which 13 articles fulfilled the inclusion/exclusion criteria with 12 articles focused on costs of management of SCI/D veterans; and, one cost-effectiveness analysis. Overall, the health care costs for the management of SCI/D veterans are substantial ($30,770 to $62,563 in 2016 USD per year) and, generally, greater than the costs of caring for patients with other chronic diseases. The most significant determinants of the higher total health-care costs are cervical level injury, complete injury, time period (i.e. first year post-injury and end-of-life year), and presence of pressure ulcers.There is growing evidence for the economic burden of SCI/D and its determinants among veterans, whereas there is a paucity of comparative studies on interventions including cost-effectiveness analyses. Further investigations are needed to fulfill significant knowledge gaps on the economics of caring for veterans with SCI/D.

Introduction Current tertiary Spinal Cord Injury (SCI) rehabilitation funding and rehabilitation length of stay (R-LOS) in most North American jurisdictions are linked to an individual’s impairment. Our objectives were to: 1) describe the impact of relevant demographic, impairment and medical complexity variables at rehabilitation admission on R-LOS among adult Canadians with traumatic SCI; and 2) identify factors which extend R-LOS. Methods Data from 1,376 adults with traumatic SCI were obtained via chart abstraction and administrative data linkage from 15 Rick Hansen SCI Registry sites (2004–2014). Variables included age, sex, neurological impairment (level, severity), rehabilitation onset days, R-LOS, Glasgow Coma Score (GCS) at admission, prior ventilation or endotracheal tube (Vent/ETT), or indwelling bladder catheter at acute discharge, pain interference score, intensive care unit (ICU) length of stay (LOS), and lower extremity motor scores (LEMS) at rehabilitation admission. Variables related to R-LOS in bivariate analysis were included in multivariate analysis to determine their impact on R-LOS. Results Prior Vent/ETT tube, indwelling bladder catheter, GCS, LEMS, and neurological impairment were related to R-LOS in bivariate analysis. Multivariate linear regression analyses identified five variables as significant predictors: age, Vent/ETT for >24 hours in acute care, indwelling bladder catheter at acute discharge, LEMS, and NLI/AIS subgroup at rehabilitation admission explained 32% of the variation in R-LOS (p

Context: Endocrine-metabolic disease (EMD) risk following spinal cord injury (SCI) is associated with significant multi-morbidity (i.e. fracture, diabetes, heart disease), mortality, and economic burden. It is unclear to what extent rehabilitation interventions can modify EMD risk and improve health status in community-dwelling adults with chronic SCI. Objectives: To characterize rehabilitation interventions and summarize evidence on their efficacy/effectiveness to modify precursors to EMD risk in community-dwelling adults with chronic SCI. Methods: Systematic searches of MEDLINE PubMed, EMBASE Ovid, CINAHL, CDSR, and PsychInfo were completed. All randomized, quasi-experimental, and prospective controlled trials comparing rehabilitation/therapeutic interventions with control/placebo interventions in adults with chronic SCI were eligible. Two authors independently selected studies and abstracted data. Mean differences of change from baseline were reported for EMD risk outcomes. The GRADE approach was used to rate the quality of evidence. Results: Of 489 articles identified, 16 articles (11 studies; n=396) were eligible for inclusion. No studies assessed the effects of rehabilitation interventions on incident fragility fractures, heart disease, and/or diabetes. Individual studies reported that exercise and/or nutrition interventions could improve anthropometric indices, body composition/adiposity, and biomarkers. However, there were also reports of non-statistically significant between-group differences. Conclusions: There was very low-quality evidence that rehabilitation interventions can improve precursors to EMD risk in community-dwelling adults with chronic SCI. The small number of studies, imprecise estimates, and inconsistency across studies limited our ability to make conclusions. A high-quality longitudinal intervention trial is needed to inform community-based rehabilitation strategies for EMD risk after chronic SCI.

Aims To describe the association between cardiovascular risk factors and abnormal arterial stiffness, defined by a carotid-femoral pulse wave velocity ≥ 10 m/s, in patients with chronic spinal cord injury (SCI). Methods Ninety consenting adults with chronic SCI (C1-T10 ASIA Impairment Scale A-D) participated in this cross-sectional study. The cardiovascular risk factors considered included age, sex, duration of injury, neurological level of injury (C1-T1, tetraplegia; T2-T12, paraplegia), age at injury, impairment scale category, supine resting systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, leisure time physical activity, treated hypertension, treated hyperlipidemia, diabetes, lipid profiles, fasting blood glucose, glycated hemoglobin, and C reactive protein. Logistic regression analysis was used to determine the association between abnormal arterial stiffness and dichotomized cardiovascular risk factors. Results Dichotomized variables significantly associated with increased arterial stiffness were: age ≥ 52 years (OR 22.1, CI 4.28-113.99); systolic blood pressure ≥ 130 mmHg (OR 11.76, CI 2.89-47.88); heart rate ≥ 62 bpm (OR 6.62, CI 1.33-33.03); and paraplegia (OR 4.26, CI 1.00-18.33). The area under the receiver operating characteristic curve for probability of arterial stiffness was 0.920 (95% CI 0.861-0.978, p

Context: Spinal cord injury or disease (SCI/D) leads to unchanged low-density lipoprotein and cholesterol, very low high-density lipoprotein a form of dyslipidemia and physical inactivity which combine to increase risk of morbidity and mortality from cardiometabolic disease. Herein, we describe the selection of structure, process and outcome indicators for adults in the first 18 months post-SCI/D rehabilitation admission. Methods: A Pan-Canadian Cardiometabolic Health Working Group was formed to develop a construct definition. Cardiometabolic risk factors were summarized in a Driver diagram. Release of the Paralyzed Veterans of America "Identification and Management of Cardiometabolic Risk after Spinal Cord Injury" and the International Scientific Exercise Guidelines: "Evidence-based scientific exercise guidelines for adults with spinal cord injury", informed the group's focus on prevention strategies to advance this Domain of rehabilitation admission. Results: The structure indicator identifies during rehabilitation the presence of appropriate time and resources for physical exercise prescription. Process indicators are lipid profile assessment at rehabilitation admission and documented exercise prescriptions prior to discharge. The outcome indicators track patient's knowledge retention regarding exercise prescription at discharge, current exercise adherence and lipid status 18 months after rehabilitation discharge. Conclusion: Routine national implementation of these indicators at the specified time points will enhance efforts to detect dyslipidemia and assure routine participation in endurance exercise. These indicators align with international initiatives to improve cardiometabolic health through interventions targeting modifiable risk factors specifically endurance exercising and optimal lipid profiles, crucial to augmenting cardiometabolic health after SCI/D.

Objective: To describe the development of structure, process and outcome indicators that will advance the quality of walking rehabilitation for Canadians with spinal cord injury or disease (SCI/D) by 2020. Method: A framework for the evaluation of the quality of walking rehabilitation was developed by experts in walking after SCI/D. A systematic literature review identified factors influencing walking outcomes and potential walking indicators. A Driver diagram analysis summarized the factors affecting walking outcomes and subsequently informed the selection of structure and process indicators. Psychometric properties and clinical utility of potential walking indicators were considered during the selection of outcome indicators. Results: The structure indicator is the number of physical therapists using evidence-based walking interventions per number of ambulatory individuals with SCI/D. The process indicator is the number of received hours of walking interventions during inpatient rehabilitation per number of ambulatory individuals with SCI/D. The intermediary outcome indicator, which is collected at discharge from inpatient rehabilitation, is either the modified Timed Up and Go or the 10-Meter Walk Test, the choice of measure is dictated by the stage of walking recovery, as defined by the Standing and Walking Assessment Tool. The final outcome indicator, collected at 18 months post-discharge, is the Spinal Cord Independence Measure III-Mobility subscale. Conclusion: The selected indicators align with current clinical practice in Canada. The indicators will direct the timing and enhance the volume of walking therapy delivered, to ultimately increase the proportion of patients who achieve their walking potential by 18 months post-rehabilitation.

Context/Objective: The potential effects of sex on injury severity and outcomes after acute spine trauma (AST) have been reported in pre-clinical and clinical studies, even though the data are conflicting. This study compared females and males regarding the epidemiology, injury characteristics, and clinical outcomes of AST. Design: Retrospective cohort study. Setting: Acute spine care quaternary center. Participants: All consecutive cases of AST admitted from January/1996 to December/2007 were included. Interventions: None. Outcome Measures: The potential effects of sex on the epidemiology, injury characteristics, and clinical outcomes of AST were studied. Results: There were 504 individuals with AST (161 females, 343 males; mean age of 49.44 ± 0.92 years). Sex was not associated with age or pre-existing co-morbidities as assessed using the Charlson Co-morbidity Index, however, females had a greater number of International Classifications of Diseases (ICD) codes at admission and higher Cumulative Illness Rating Scale (CIRS) than males. Over the 12-year period, the male-to-female ratio has not significantly changed. Although there were significant sex-related discrepancies regarding injury etiology, level and severity of AST, males and females had similar lengths of stay in the acute spine center, in-hospital survival post-AST, and need for mechanical ventilation and tracheostomy. Conclusion: This study suggests that females with AST present with a greater number of pre-existing co-morbidities, a higher frequency of thoraco-lumbar trauma, less severe neurological impairment and a greater proportion of MVA-related injuries. However, females and males have a similar length of stay in the acute spine center, and comparable in-hospital survival, need for mechanical ventilation, and tracheostomy after AST.

Objectives: To prioritize Domains of SCI Rehabilitation Care (SCI-Care) based on clinical importance and feasibility to inform the development of indicators of quality SCI-Care for adults with SCI/D in Canada. Methods: A 17-member external advisory committee, comprised of key stakeholders, ranked 15/37 Domains of rehabilitation previously flagged by the E-scan project team for gaps between knowledge generation and clinical implementation. Priority scores (D) were calculated using the Hanlon formula: D=[A+(2×B)]×C, where A is prevalence, B is seriousness, and C is the effectiveness of available interventions. A modified “EAARS” (Economic, Acceptability, Accessibility, Resources, and Simplicity) criterion was used to rank feasibility on a scale of 0–4 (4 is high). The product of these two scores determined the initial Domain ranking. Following the consensus process, further changes were made to the Domain rankings. Results: Despite a low feasibility score, Sexual Health was ranked as high priority; and, the Community Participation and Employment Domains were merged. The 11 final prioritized Domains in alphabetic order were: Cardiometabolic Health; Community Participation and Employment; Emotional Well-Being; Reaching, Grasping, and Manipulation; Self-Management; Sexual Health; Tissue Integrity; Urinary Tract Infection; Urohealth; Walking, and Wheeled Mobility. Conclusions: The modified Hanlon method was used to facilitate prioritization of 11 of 37 Domains to advance the quality of SCI-care by 2020. In future, the Spinal Cord Injury Rehabilitation Care High Performance Indicators (SCI-High) Project Team will develop structure, process and outcome indicators for each prioritized Domain.

Context: Individuals with spinal cord injury or disease (SCI/D) are at increased risk of depression, which is associated with poor short- and long-term outcomes. Accurate diagnosis is complicated by overlapping symptoms of both conditions, and a lack of consensus-derived guidelines specifying an appropriate depression screening tool. Objective: To conduct a systematic review to: (1) identify the diagnostic accuracy of established depression screening tools compared to clinical assessment; and, (2) to summarize factors that influence feasibility of clinical implementation among adults with SCI/D. Methods: A systematic search using MEDLINE, EMBASE, PsycINFO, CINAHL and the Cochrane databases using the terms spinal cord injury, depression or mood disorder, and screening or diagnosis identified 1254 initial results. Following duplicate screening, five articles assessing eight screening tools met the final inclusion and exclusion criteria. Measures of diagnostic accuracy and feasibility of implementation were extracted. The Quality Assessment Tool for Diagnostic Accuracy Studies 2 (QUADAS-2) was used to assess study quality. Results: The Patient Health Questionnaire-9 (PHQ-9) had the highest sensitivity (100%), and specificity (84%). The 2-item version, the PHQ-2, comprised the fewest questions, and six of the eight tools were available without cost. Utilizing the QUADAS-2 tool, risk of bias was rated as low or unclear risk for all studies; applicability of the results was rated as low concern. Conclusion: The PHQ-9 is an accurate and feasible tool for depression screening in the adult SCI/D population. Future studies should evaluate the implementation of screening tools and the impact of screening on access to mental health interventions.

Background: Wheeled mobility is critical for individuals with Spinal Cord Injury or Disease (SCI/D) related paralysis. The World Health Organization (WHO) developed guidelines highlighting eight steps in wheelchair service delivery: (1) referral and appointment; (2) assessment; (3) prescription; (4) funding and ordering; (5) product preparation; (6) fitting; (7) user training; and, (8) follow-up maintenance/repairs. This article describes the processes used to develop structure, process and outcome indicators that reflect the WHO guidelines within the Domain of Wheeled Mobility rehabilitation for Canadians. Methods: Wheeled mobility experts within the SCI-High Project Team used the WHO guideline to inform the Construct refinement and development of a Driver diagram. Following seven meetings, the Driver diagram and review of outcome measures and literature synthesis regarding wheelchair service delivery informed indicator selection and group consensus. Results: The structure indicator examines the proportion of SCI/D service providers within a rehabilitation program who have specialized wheelchair training to ensure prescription, preparation, fitting, and maintenance quality. The process indicator evaluates the average number of hours of wheelchair service delivery provided per patient during rehabilitation. The intermediary outcome indicator (rehabilitation discharge), is a target capacity score on the Wheelchair Skills Test Questionnaire (WST-Q). The final outcome indicators (at 18 months post rehabilitation admission) are the Life Space Assessment (LSA) and the Wheelchair Use Confidence Scale (WheelCon) short form mean scores. Conclusion: Routine implementation of the selected Wheeled Mobility structure, process and outcome indicators should measurably advance care within the Wheeled Mobility Domain for Canadians living with SCI/D by 2020.

Background: High-quality rehabilitation care following spinal cord injury or disease (SCI/D) is critical for optimizing neurorecovery and long-term health outcomes. This manuscript describes the methods used for developing, refining, and implementing a framework of structure, process, and outcome indicators that reflect high-quality rehabilitation among adults with SCI/D in Canada. Methods: This quality improvement initiative was comprised of the following processes: (1) prioritization of care Domains by key stakeholders (scientists, clinicians, therapists, patients and stakeholder organizations); (2) assembly of 11 Domain-specific Working Groups including 69 content experts; (3) conduct of literature searches, guideline and best practice reviews, and outcome synthesis by the Project Team; (4) refinement of Domain aim and construct definitions; (5) conduct of cause and effect analysis using Driver diagrams; (6) selection and development of structure, process and outcome indicators; (7) piloting and feasibility analysis of indicators and associated evaluation tools; and, (8) dissemination of the proposed indicators. Result: The Project Team established aims, constructs and related structure, process, and outcome indicators to facilitate uniform measurement and benchmarking across 11 Domains of rehabilitation, at admission and for 18 months thereafter, among adult Canadians by 2020. Conclusion: These processes led to the selection of a feasible set of indicators that once implemented should ensure that adults with SCI/D receive timely, safe, and effective rehabilitation services. These indicators can be used to assess health system performance, monitor the quality of care within and across rehabilitation settings, and evaluate the rehabilitation outcomes of the population to ultimately enhance healthcare quality and equity.

Objective: To establish structure, process and outcome indicators to evaluate tissue integrity in Canadians with spinal cord injury or disease (SCI/D) in the first 18 months following inpatient rehabilitation admission. Method: A Working Group comprised of Canadian subject matter experts in the Domain of Tissue Integrity was formed to define the construct of tissue integrity. A literature review was conducted and a Driver diagram produced to identify factors that influence tissue integrity in individuals with SCI/D. Facilitated meetings were conducted to identify and achieve consensus on structure, process and outcome indicators. Rapid cycle testing was used to pilot test proposed indicators for face validity and feasibility within a quality improvement context. Results: The structure indicators are the proportion of patients with SCI/D who have access to a mirror for skin checks and the proportion of patients who have access to patient education on tissue integrity; the process indicator is the proportion of patients who completed daily head-to-toe skin checks; the intermediary outcome indicator is pressure injury (PI) incidence during inpatient rehabilitation; and the final outcome indicator is the proportion of individuals with intact skin at 18 months following rehabilitation admission. Conclusion: The set of indicators established for the Domain of Tissue Integrity are specifically focused on aspects of care that can impact the maintenance of tissue integrity and the prevention of PI and align with current practice guidelines. The implementation and evaluation of these indicators nationally have the potential to improve care for Canadians with SCI/D.

Context/Objective: Prior studies indicate that patient’s gender and age can influence treatment choices during spine disease management. This study examines whether individual’s gender and age at injury onset influence the waiting time for each step in the surgical management of patients with acute traumatic cervical spinal cord injury (atcSCI). Design: Retrospective cohort study. Setting: Quaternary spine trauma center. Participants: This study included consecutive individuals with atcSCI admitted from August/2002 to October/2008 who were enrolled in the Surgical Trial in Acute Spinal Cord Injury Study (STASCIS). Interventions: Spinal cord decompression. Outcome Measures: Data on the periods of time for each step in the surgical management were analyzed to explore the potential effects of gender and age at injury onset. Results: There were 64 individuals with atcSCI (17 women, 47 men; age range: 18–78 years; mean age: 50.5 ± 2.1 years). Older age was associated with longer stay in the acute spine center, but this association was cofounded by major pre-existing medical co-morbidities. Age did not significantly affect the waiting time for each step in the surgical management of these individuals with atcSCI. Women underwent surgical assessment earlier than men. Gender did not influence other key steps in the surgical management. Conclusion: The study results suggest that older age at injury onset was associated with longer stay in the acute spine care center, and women had a shorter waiting time for surgical assessment than men. Nevertheless, no other age or gender bias was identified in the waiting times for the steps in the management of atcSCI.

STUDY DESIGN: Case series. OBJECTIVES: This case series describes how the aquatic environment influences gait initiation in terms of the center of pressure (COP) excursion, impulses, trunk acceleration, and perceptions of participants with incomplete spinal cord injury (iSCI). SETTING: Tertiary Rehabilitation Hospital, Ontario, Canada. METHODS: Five individuals with iSCI (four cervical injuries/one thoracic injury, AIS D) participated in the study. Baseline clinical balance was evaluated by Berg Balance Scale and Mini-Balance Evaluation System Test. Participants initiated gait on a waterproof force plate and walked ~4 steps, in water and on land. COP trajectories during anticipatory and execution phases, impulses, and trunk acceleration parameters were investigated. Perceptions of walking in both environments were obtained using an interview. RESULTS: COP trajectory was prominently longer when individuals stepped forward. A decrease in velocity of COP was observed predominantly in the AP direction during stepping. Non-normalized vertical impulses decreased as the AP impulses increased, in water compared to land. Upper to lower trunk acceleration ratios showed how water resistance influenced the lower trunk acceleration. Most of participants reported that walking in water was challenging, but safer than on land. CONCLUSIONS: Participants with higher balance function seemed to have more pronounced changes in anticipatory and execution phases’ duration, length and velocity of COP. A faster anticipatory phase and a slower execution phase were observed in water than on land. Participants walked in water using a different trunk control strategy than on land and reported no fear of falling when walking in water versus land.

This pilot study explored the feasibility of using an e-consultation service to link family physicians with physiatrists to improve timely access to information and advice regarding SCI care. Sixteen family physicians and two tertiary care physiatrists were recruited. Family physicians could access physiatrists using a secure e-consultation system. Following pilot testing, nine physicians and two physiatrists completed an individual interview to obtain their perceptions of the service. The number and reasons for e-consultation were tracked. A total of 14 e-consultations were completed, most frequently for bladder (n=4) and bowel issues (n=4). Analysis generated six themes regarding e-consultation: (i) provides improved access to SCI information and expertise, (ii) can avoid specialist referrals and emergency department visits, (iii) is easy and convenient to use, (iv) is a secured system; (v) is facilitated by dedicated resource support, (vi) is limited by the system (technological) constraints. A SCI specific e-consultation service can provide family physicians with timely access to advice not otherwise easily available and that has a direct impact on patient care. Larger scale studies are needed to explore impacts on capacity building in primary care, health system utilization, and patient health and well-being.

Purpose: To describe objective social disconnectedness and perceived social isolation post-spinal cord injury/dysfunction (SCI/D), and to examine associations among social disconnectedness and social isolation by sociodemographic and clinical characteristics. Materials and Methods: A telephone-based questionnaire was administered to 170 community dwelling individuals with a SCI/D. Social disconnectedness was measured by social network size, composition, and frequency of contact. Social isolation was measured using the revised three item UCLA Loneliness Scale. Results: Of the 170 participants, the majority were men (n = 136, 80%), had a traumatic injury (n = 149, 87.6%), and had incomplete tetraplegia (n = 58, 34%). The mean network size was 3.86 (SD = 2.0) of a maximum seven. The mean loneliness score for the sample was 4.93 (SD = 1.87). Factors associated with lower feelings of loneliness included being married, living with a higher proportion of network members, and being employed. Size of networks was not significantly associated with feelings of loneliness. Conclusions: This study highlights the vulnerability for perceived social isolation among persons with SCI/D. The size of network does not seem to matter as much as the frequency and quality of social interactions. Findings reinforce the complexity of social disconnectedness and the importance in understanding the various indicators of social disconnectedness as they relate to social isolation.IMPLICATIONS FOR REHABILITATIONSocial relationships have been shown to be a vital component of optimal health and well-being.Individuals with a spinal cord injury/dysfunction are faced with a number of challenges in developing and maintaining social relationships and community participation.Rehabilitation professionals should encourage opportunities for social inclusion, employment and community participation to optimize health and well-being for this population.

Objective This cost-utility analysis was undertaken to compare early (≤24 hours since trauma) versus delayed surgical decompression of spinal cord to determine which approach is more cost effective in the management of patients with acute traumatic cervical spinal cord injury (SCI). Methods This study includes the patients enrolled into the Surgical Timing in Acute Spinal Cord Injury Study (STASCIS) and admitted at Toronto Western Hospital. Cases were grouped into patients with motor complete SCI and individuals with motor incomplete SCI. A cost-utility analysis was performed for each group of patients by the use of data for the first 6 months after SCI. The perspective of a public health care insurer was adopted. Costs were estimated in 2014 U.S. dollars. Utilities were estimated from the STASCIS. Results The baseline analysis indicates early spinal decompression is more cost-effective approach compared with the delayed spinal decompression. When we considered the delayed spinal decompression as the baseline strategy, the incremental cost-effectiveness ratio analysis revealed a saving of US$ 58,368,024.12 per quality-adjusted life years gained for patients with complete SCI and a saving of US$ 536,217.33 per quality-adjusted life years gained in patients with incomplete SCI for the early spinal decompression. The probabilistic analysis confirmed the early-decompression strategy as more cost effective than the delayed-decompression approach, even though there is no clearly dominant strategy. Conclusions The results of this economic analysis suggests that early decompression of spinal cord was more cost effective than delayed surgical decompression in the management of patients with motor complete and incomplete SCI, even though no strategy was clearly dominant.

Cardiovascular disease (CVD) is currently the leading cause of mortality among individuals living with chronic spinal cord injury (SCI). The purpose of this study is to: 1) Describe the prevalence of CVD risk factors including dyslipidemia (DYS), hypertension (HTN) and type II diabetes mellitus (DM) in patients with chronic SCI; 2) Report the frequency of individuals recommended for diagnostic testing, as per current Canadian CVD diagnostic guidelines; and 3) Report the frequency of individuals receiving guideline-derived appropriate therapy for these risk factors.Adults with a chronic, stable SCI (n = 91) were included in this study. Medical histories, current medications, blood serum analyses and blood pressures were collected and compared to current Canadian CVD diagnostic guidelines to assess for DYS, HTN and DM.Of the 81 participants with blood serum analyses, 10 (14.7%) of 23 (28.4%) individuals meeting diagnostic criteria for DYS were not taking appropriate statin medication and 2 (2.5%) of 7 (8.6%) individuals meeting diagnostic criteria for DM were not taking appropriate DM medication. Of the 91 participants having BP measurements, 13 (14.3%) of 26 (28.6%) individuals meeting diagnostic criteria for HTN were not taking appropriate BP medication.In addition to a high prevalence of CVD risk factors among individuals with chronic SCI, there is also evidence of poor adherence to diagnostic and treatment guidelines for DYS, HTN and DM. The study results highlight an important gap between the observed prevalence of disease and the low rates of screening and guideline adherence in the SCI population.

Background Deep Tissue Pressure Injury (DTI) occurs in the tissues underlying the skin that may not have visible signs of skin breakdown and may be detected by ultrasound. The optimal position for ischial region ultrasound image acquisition to facilitate assessment of the tissue proximal to the ischias not been determined. Objective To evaluate the mean difference in geometric and grey scale measures of tissues overlying the ischial tuberosity (IT) acquired from ultrasound images in supine and lateral recumbent simulated sitting positions from adults with spinal cord impairment (SCI). Methods Nine individuals (3 acute and 6 chronic) with SCI or disease with neurological level of injury C4-T12 and AIS A-D and who used a wheelchair for mobility were recruited and underwent ultrasound acquisition in the supine and lateral recumbent positions. One participant was imaged twice on a separate day. Three images from the left (n = 8) and right (n = 2) IT were scanned using a 6 – 18 MHz linear ultrasound probe (Acuson S2000) with participants’ hips and knees flexed to 90° in both the supine and lateral recumbent positions using a single rater protocol. MATLAB Image Processing Toolbox with a customized script was used to obtain mean and maximal thickness, echogenicity and contrast of skin, subcutaneous tissue and muscle. Wilcoxon Signed Rank Test and Bland Altman analysis was used to determine if there were differences between the two image acquisition positions and to construct limits of agreement. Results Thickness and contrast measures were similar in the supine and lateral recumbent positions (p > 0.05). Muscle echogenicity was lower in the supine position (p = 0.04). Conclusion There is agreement in geometric and grey scale measures of tissues over the IT between the supine and lateral recumbent positions with the exception of muscle echogenicity, which was lower in the supine position. Since DTI is thought to originate in the muscle and echogenicity plays in a role in abnormal tissue imaging diagnosis, further studies are recommended to determine the impact of body position on muscle echogenicity prior to being used in prospective studies.

Objectives: The primary objective was to review the literature regarding methodologies to assess fracture risk, to prevent and treat osteoporosis and to manage osteoporotic fractures in SCI/D. Study Design: Scoping review. Settings/Participants: Human adult subjects with a SCI/D. Outcome measures: Strategies to identify persons with SCI/D at risk for osteoporotic fractures, nonpharmacological and pharmacological therapies for osteoporosis and management of appendicular fractures. Results: 226 articles were included in the scoping review. Risk of osteoporotic fractures in SCI is predicted by a combination of DXA-defined low BMD plus clinical and demographic characteristics. Screening for secondary causes of osteoporosis, in particular hyperparathyroidism, hyperthyroidism, vitamin D insufficiency and hypogonadism, should be considered. Current antiresorptive therapies for treatment of osteoporosis have limited efficacy. Use of surgery to treat fractures has increased and outcomes are good and comparable to conservative treatment in most cases. A common adverse event following fracture was delayed healing. Conclusions: Most of the research in this area is limited by small sample sizes, weak study designs, and significant variation in populations studied. Future research needs to address cohort definition and study design issues.

OBJECTIVEAcute spine trauma (AST) has a relatively low incidence, but it often results in substantial individual impairments and societal economic burden resulting from the associated disability. Given the key role of neurosurgeons in the decision-making regarding operative management of individuals with AST, the authors performed a systematic search with scoping synthesis of relevant literature to review current knowledge regarding the economic burden of AST.METHODSThis systematic review with scoping synthesis included original articles reporting cost-effectiveness, cost-utility, cost-benefit, cost-minimization, cost-comparison, and economic analyses related to surgical management of AST, whereby AST is defined as trauma to the spine that may result in spinal cord injury with motor, sensory, and/or autonomic impairment. The initial literature search was carried out using MEDLINE, EMBASE, CINAHL, CCTR, and PubMed. All original articles captured in the literature search and published from 1946 to September 27, 2017, were included. Search terms used were the following: (cost analysis, cost effectiveness, cost benefit, economic evaluation or economic impact) AND (spine or spinal cord) AND (surgery or surgical).RESULTSThe literature search captured 5770 titles, of which 11 original studies met the inclusion/exclusion criteria. These 11 studies included 4 cost-utility analyses, 5 cost analyses that compared the cost of intervention with a comparator, and 2 studies examining direct costs without a comparator. There are a few potentially cost-saving strategies in the neurosurgical management of individuals with AST, including 1) early surgical spinal cord decompression for acute traumatic cervical spinal cord injury (or traumatic thoracolumbar fractures, traumatic cervical fractures); 2) surgical treatment of the elderly with type-II odontoid fractures, which is more costly but more effective than the nonoperative approach among individuals with age at AST between 65 and 84 years; 3) surgical treatment of traumatic thoracolumbar spine fractures, which is implicated in greater direct costs but lower general-practitioner visit costs, private expenditures, and absenteeism costs than nonsurgical management; and 4) removal of pedicle screws 1–2 years after posterior instrumented fusion for individuals with thoracolumbar burst fractures, which is more cost-effective than retaining the pedicle screws.CONCLUSIONSThis scoping synthesis underscores a number of potentially cost-saving opportunities for neurosurgeons when managing patients with AST. There are significant knowledge gaps regarding the potential economic impact of therapeutic choices for AST that are commonly used by neurosurgeons.

Purpose: To provide an overview of the feasibility and outcomes of robotic-assisted upper extremity training for individuals with cervical spinal cord injury (SCI), and to identify gaps in current research and articulate future research directions. Materials and methods: A systematic search was conducted using Medline, Embase, PsycINFO, CCTR, CDSR, CINAHL and PubMed on June 7, 2017. Search terms included 3 themes: (1) robotics; (2) SCI; (3) upper extremity. Studies using robots for upper extremity rehabilitation among individuals with cervical SCI were included. Identified articles were independently reviewed by two researchers and compared to pre-specified criteria. Disagreements regarding article inclusion were resolved through discussion. The modified Downs and Black checklist was used to assess article quality. Participant characteristics, study and intervention details, training outcomes, robot features, study limitations and recommendations for future studies were abstracted from included articles. Results: Twelve articles (one randomized clinical trial, six case series, five case studies) met the inclusion criteria. Five robots were exoskeletons and three were end-effectors. Sample sizes ranged from 1 to 17 subjects. Articles had variable quality, with quality scores ranging from 8 to 20. Studies had a low internal validity primarily from lack of blinding or a control group. Individuals with mild-moderate impairments showed the greatest improvements on body structure/function and performance-level measures. This review is limited by the small number of articles, low-sample sizes and the diversity of devices and their associated training protocols, and outcome measures. Conclusions: Preliminary evidence suggests robot-assisted interventions are safe, feasible and can reduce active assistance provided by therapists.Implications for rehabilitationRobot-assisted upper extremity training for individuals with cervical spinal cord injury is safe, feasible and can reduce hands-on assistance provided by therapists.Future research in robotics rehabilitation with individuals with spinal cord injury is needed to determine the optimal device and training protocol as well as effectiveness. Robot-assisted upper extremity training for individuals with cervical spinal cord injury is safe, feasible and can reduce hands-on assistance provided by therapists. Future research in robotics rehabilitation with individuals with spinal cord injury is needed to determine the optimal device and training protocol as well as effectiveness.

Understanding the related fates of muscle density and bone quality after chronic spinal cord injury (SCI) is an important initial step in determining endocrine-metabolic risk.To examine the associations between muscle density and indices of bone quality at the distal lower extremity of adults with chronic SCI.A secondary data analysis was conducted in 70 adults with chronic SCI (C2-T12; American Spinal Injury Association Impairment Scale [AIS] A-D; ≥2 years post injury). Muscle density and cross-sectional area (CSA) and bone quality indices (trabecular bone mineral density [TbBMD] at the distal tibia [4% site] and cortical thickness [CtTh], cortical area [CtAr], cortical BMD [CtBMD], and polar moment of inertia [PMI] at the tibial shaft [66% site]) were measured using peripheral quantitative computed tomography. Calf lower extremity motor score (cLEMS) was used as a clinical measure of muscle function. Multivariable linear regression analyses were performed to determine the strength of the muscle-bone associations after adjusting for confounding variables (sex, impairment severity [AIS A/B vs AIS C/D], duration of injury, and wheelchair use).Muscle density was positively associated with TbBMD (b = 0.85 [0.04, 1.66]), CtTh (b = 0.02 [0.001, 0.034]), and CtBMD (b = 1.70 [0.71, 2.69]) (P.05). Muscle CSA was most strongly associated with CtAr (b = 2.50 [0.12, 4.88]) and PMI (b = 731.8 [161.7, 1301.9]) (P.05), whereas cLEMS was most strongly associated with TbBMD (b = 7.69 [4.63, 10.76]) (P.001).Muscle density and function were most strongly associated with TbBMD at the distal tibia in adults with chronic SCI, whereas muscle size was most strongly associated with bone size and geometry at the tibial shaft.

(1) to inform the development of health system quality indicators for traumatic and non-traumatic spinal cord injury from acute care admission to community care discharge using administrative data, and (2) to examine characteristics and differences in care among type of care facility, and type of pathology using administrative data.Retrospective cohort study using administrative health data.Ontario, Canada.Using administrative health data, we used International Classification codes 10(th) version Canadian Edition to identify incident cases of SCI from April 1, 2006 to March 31, 2012.We identified 7,693 cases in our cohort, of whom 1,537 (20.0%) were categorized as traumatic spinal cord (TSCI) and 6,156 (80.0%) as non-traumatic (NTSCI). Of those identified with NTSCI, more than half (54.0%) were diagnosed with either Guillain Barré syndrome and Multiple Sclerosis (n = 3,326). More individuals admitted to a trauma/spine center were seen by an orthopedic surgeon or a neurosurgeon (20.3% compared to 5.6% for NTSCI; 77.7% compared to 24.9% for TSCI). Only 25.7% (n = 724) of the NTSCI cohort were admitted to a rehabilitation facility from a trauma/spine center, compared to 58.9% (n = 754) of those with TSCI.Important challenges in data completeness and utility were identified. Province wide processes to flag incomplete data and provision of incentives for comprehensive data are urgently needed to develop quality indicators across the care continuum. Consensus on the coding for NTSCI for the purposes of developing health system indicators is required.

To compare and describe demographic characteristics, clinical, and survival outcomes in patients admitted for inpatient rehabilitation following malignant spinal cord compression (MSCC) or other causes of non-traumatic spinal cord injury (NT-SCI).A retrospective cohort design was employed, using data retrieved from administrative databases.Rehabilitation facilities or designated rehabilitation beds in Ontario, Canada, from April 2007 to March 2011.Patients with incident diagnoses of MSCC (N = 143) or NT-SCI (N = 1,274) admitted for inpatient rehabilitation.Demographic, impairment, functional outcome (as defined by the Functional Independence Measure (FIM)), discharge, healthcare utilization, survival, and tumor characteristics.There was a significant improvement in the FIM from admission to discharge (mean change 20.1 ± 14.3,0.001) in the MSCC cohort. NT-SCI patients demonstrated a higher FIM efficiency (1.2 ± 1.7 vs. 0.8 ± 0.8,0.001) and higher total (24.0 ± 14.4 vs. 20.1 ± 14.3,0.001) FIM gains relative to MSCC cases. However, there were no differences between the MSCC and NT-SCI cohorts in length of stay (34.6 ± 30.3 vs. 37.5 ± 35.2, P = 0.8) or discharge FIM (100.7 ± 19.6 vs. 103.3 ± 18.1, P = 0.1). Three-month, 1-year, and 3-year survival rates in the MSCC and NT-SCI cohorts were 76.2% vs. 97.6%, 46.2% vs. 93.7%, and 27.3% vs. 86.7%, respectively. The majority (65.0%) of patients with MSCC was discharged home and met their rehabilitation goals (75.5%) at comparable rates to patients with NT-SCI (69.7 and 81.3%).Despite compromised survival, patients with MSCC make clinically significant functional gains and exhibit favorable discharge outcomes following inpatient rehabilitation. Current administrative data suggests the design and scope of inpatient rehabilitation services should reflect the unique survival-related prognostic factors in patients with MSCC.

Qualitative follow-up study. Intensive locomotor training can improve physical and psychological functioning for individuals with spinal cord injury. Few studies have examined long-term effects of locomotor training. Specifically, there is a lack of qualitative follow-up that provide insight into participants’ perceptions of the effects of locomotor training on level of function and daily life. This study aimed to gain insight into participants’ perceptions of intensive locomotor training and whether participation influenced the level of function and community living 1–2 years after training. Tertiary rehabilitation facility in Ontario, Canada. Participants were six individuals who had lived with spinal cord injury between 1.9 and 2.7 years at the time of the interviews and had completed locomotor training during the subacute phase of injury. Semi-structured interviews explored participants’ daily experiences and level of function after locomotor training. Interviews were analyzed using thematic analysis. Three themes were identified. (1) Outcomes: Personalized Adapted Locomotor Training led to transferable gains from the program to daily functioning and eased transitions out of the rehabilitation hospital. (2) Continuing the rehabilitation journey: following disappointment after training ended, recovery was perceived incomplete regardless of current functional status. Endeavors were now directed to maintaining gains achieved during the program. (3) Challenges: since discharge from Personalized Adapted Locomotor Training, participants identified changes in their psychological well-being and the risk of falls as challenges. Personalized Adapted Locomotor Training was a positive experience. The identified challenges present future opportunities for the improved delivery of intensive locomotor training programs.

BACKGROUND Aging of the population has prompted an escalation of service utilization and costs in many jurisdictions including North America. However, relatively little is known on the economic impact of old age on the management of acute spine trauma (AST). OBJECTIVE To examine the potential effects of age on the service utilization and costs of the management of patients with acute spine trauma. METHODS This retrospective cohort study included consecutive patients with AST admitted to an acute spine care unit of a Canadian quaternary university hospital between February, 2002 and September, 2007. The study population was grouped into elderly (≥65 yr) and younger individuals. All costing data were converted and updated to US dollars in June/2017. RESULTS There were 55 women and 91 men with AST (age range: 16-92 yr, mean age of 49.9 yr) of whom 37 were elderly. The mean total hospital costs for initial admission after AST in the elderly (USD $19 338 ± $4892) were significantly greater than among younger individuals (USD $13 775 ± $1344). However, elderly people had significantly lower per diem total, fixed, direct, and indirect costs for AST than younger individuals. Both groups were comparable regarding the proportion of services utilized in the acute care hospital. CONCLUSION Given the escalating demand for surgical and nonsurgical spine treatment in the age of aging population, the timely results of this study underline key aspects of the economic impact of the spine care of the elderly. Further investigations are needed to fulfill significant knowledge gaps on the economics of caring for elderly with AST.

A pilot study to evaluate the therapeutic potential of 40 weeks of passive standing with whole body vibration (PS-WBV) on central and peripheral arterial stiffness among men with chronic spinal cord injury (SCI).Consenting participants were pre-screened to ensure safe participation. Fifteen individuals with chronic SCI were enrolled to participate in PS-WBV sessions three times per week for 40 weeks on a modified WAVE platform custom-fitted with an EASYStand 5000. Knee angle was set at 160°, and vibration parameters were 45Hz frequency and 0.7mm displacement. Each 45-minute session of PS-WBV training was intermittent (60 seconds on and 120 seconds off). Aortic and leg pulse wave velocity (PWV) was measured at baseline, mid-point (20 weeks) and exit (40 weeks).Nine males (age 41±11 years, American Spinal Injury Association Impairment Scale A-D, neurological level of injury T4-T10, years post-injury 12±8 years) completed the intervention. Aortic PWV was collected on n=7 at exit, and leg PWV was collected on n=6 at exit. No changes over time were found for either aortic PWV (P = 0.46) or leg PWV (P = 0.54). One possible study-related serious adverse event occurred during study intervention: the development of a grade III pressure sore on the right proximal anterior shin (n=1).Forty weeks of PS-WBV in adults with SCI did not result in an observable change in arterial stiffness.

OBJECTIVES: Carotid intima-media thickness (cIMT) may be used increasingly as a cardiovascular disease (CVD) screening tool in individuals with spinal cord injury (SCI) as other routine invasive diagnostic tests are often unfeasible. However, variation in cIMT acquisition and analysis methods is an issue in the current published literature. The growth of the field is dependent on cIMT quality acquisition and analysis to ensure accurate reporting of CVD risk. The purpose of this study is to evaluate the quality of the reported methodology used to collect cIMT values in SCI. METHODS: Data from 12 studies, which measured cIMT in individuals with SCI, were identified from the Medline, Embase and CINAHL databases. The quality of the reported methodologies was scored based on adherence to cIMT methodological guidelines abstracted from two consensus papers. RESULTS: Five studies were scored as ‘moderate quality’ in methodological reporting, having specified 9 to 11 of 15 quality reporting criterion. The remaining seven studies were scored as ‘low quality’, having reported less than 9 of 15 quality reporting criterion. No study had methodological reporting that was scored as ‘high quality’. The overall reporting of quality methodology was poor in the published SCI literature. CONCLUSIONS: A greater adherence to current methodological guidelines is needed to advance the field of cIMT in SCI. Further research is necessary to refine cIMT acquisition and analysis guidelines to aid authors designing research and journals in screening manuscripts for publication.

Elevated aortic arterial stiffness (aortic pulse wave velocity: aPWV) is an independent coronary artery disease predictor among the general population. The purpose of this study was to: (1) report aPWV values in a representative cohort of patients with spinal cord injury (SCI); (2) to compare aPWV values in people with SCI based on neurological level of injury; and (3) to contrast the reported aPWV values with available normal values for the general population.Adults with chronic SCI (n = 87) were divided into two groups (TETRA group, n = 37 and PARA group, n = 50). aPWV and potential confounders of aPWV were assessed. Analysis of covariance was used for comparisons between groups and adjusted for the confounders. Subjects' aPWV values were contrasted with reference values for general population determined by "The Reference value for arterial stiffness' collaboration" and prevalence of abnormal aPWV defined as greater than or equal to the age-specific 90th percentile was reported.Prevalence of abnormal aPWV in the cohort was 25.3%. After adjusting for covariates, the mean aPWV values were significantly different between two groups (TETRA: 8.0 (95% confidence interval (CI): 7.5-8.6) m/second, PARA: 9.0 (95% CI: 8.5-9.4) m/second, P = 0.010). The prevalence of abnormal aPWV was significantly higher in the PARA group (36%) compared to the TETRA group (11%) (P = 0.012).One-quarter of the total cohort had an abnormal aPWV. Subjects with paraplegia had higher aPWV values and a higher frequency of abnormal aPWV than subjects with tetraplegia. Elevated aPWV in people with SCI, particularly those with paraplegia, may impart significant adverse cardiovascular consequences.

Multi-channel surface functional electrical stimulation (FES) for walking has been used to improve voluntary walking and balance in individuals with spinal cord injury (SCI).To investigate short- and long-term benefits of 16 weeks of thrice-weekly FES-assisted walking program, while ambulating on a body weight support treadmill and harness system, versus a non-FES exercise program, on improvements in gait and balance in individuals with chronic incomplete traumatic SCI, in a randomized controlled trial design.Individuals with traumatic and chronic (≥18 months) motor incomplete SCI (level C2 to T12, American Spinal Cord Injury Association Impairment Scale C or D) were recruited from an outpatient SCI rehabilitation hospital, and randomized to FES-assisted walking therapy (intervention group) or aerobic and resistance training program (control group). Outcomes were assessed at baseline, and after 4, 6, and 12 months. Gait, balance, spasticity, and functional measures were collected.Spinal cord independence measure (SCIM) mobility sub-score improved over time in the intervention group compared with the control group (baseline/12 months: 17.27/21.33 vs. 19.09/17.36, respectively). On all other outcome measures the intervention and control groups had similar improvements. Irrespective of group allocation walking speed, endurance, and balance during ambulation all improved upon completion of therapy, and majority of participants retained these gains at long-term follow-ups.Task-oriented training improves walking ability in individuals with incomplete SCI, even in the chronic stage. Further randomized controlled trials, involving a large number of participants are needed, to verify if FES-assisted treadmill training is superior to aerobic and strength training.

Traumatic spinal cord injury (SCI) results in substantial reductions in lower extremity muscle mass and bone mineral density below the level of the lesion. Whole-body vibration (WBV) has been proposed as a means of counteracting or treating musculoskeletal degradation after chronic motor complete SCI. To ascertain how WBV might be used to augment muscle and bone mass, we investigated whether WBV could evoke lower extremity electromyography (EMG) activity in able-bodied individuals and individuals with SCI, and which vibration parameters produced the largest magnitude of effect.Ten male subjects participated in the study, six able-bodied and four with chronic SCI. Two different manufacturers' vibration platforms (WAVE(®) and Juvent™) were evaluated. The effects of vibration amplitude (0.2, 0.6 or 1.2 mm), vibration frequency (25, 35, or 45 Hz), and subject posture (knee angle of 140°, 160°, or 180°) on lower extremity EMG activation were determined (not all combinations of parameters were possible on both platforms). A novel signal processing technique was proposed to estimate the power of the EMG waveform while minimizing interference and artifacts from the plate vibration.WBV can elicit EMG activity among subjects with chronic SCI, if appropriate vibration parameters are employed. The amplitude of vibration had the greatest influence on EMG activation, while the frequency of vibration had lesser but statistically significant impact on the measured lower extremity EMG activity.These findings suggest that WBV with appropriate parameters may constitute a promising intervention to treat musculoskeletal degradation after chronic SCI.

IntroductionRecent studies demonstrate that cardiovascular diseases and associated complications are the leading cause of morbidity and mortality in individuals with spinal cord injury (SCI). Abnormal arterial stiffness, defined by a carotid–to-femoral pulse wave velocity (cfPWV) ≥10 m/s, is a recognised risk factor for heart disease in individuals with SCI. There is a paucity of studies assessing the efficacy of conventional training modalities on arterial stiffness and other cardiovascular outcomes in this population. Therefore, this study aims to compare the efficacy of arm cycle ergometry training (ACET) and body weight-supported treadmill training (BWSTT) on reducing arterial stiffness in individuals with chronic motor complete, high-level (above the sixth thoracic segment) SCI.Methods and analysisThis is a multicentre, randomised, controlled, clinical trial. Eligible participants will be randomly assigned (1:1) into either ACET or BWSTT groups. Sixty participants with chronic (>1 year) SCI will be recruited from three sites in Canada (Vancouver, Toronto and Hamilton). Participants in each group will exercise three times per week up to 30 min and 60 min for ACET and BWSTT, respectively, over the period of 6 months. The primary outcome measure will be change in arterial stiffness (cfPWV) from baseline. Secondary outcome measures will include comprehensive assessments of: (1) cardiovascular parameters, (2) autonomic function, (3) body composition, (4) blood haematological and metabolic profiles, (5) cardiorespiratory fitness and (6) quality of life (QOL) and physical activity outcomes. Outcome measures will be assessed at baseline, 3 months, 6 months and 12 months (only QOL and physical activity outcomes). Statistical analyses will apply linear-mixed modelling to determine the training (time), group (ACET vs BWSTT) and interaction (time × group) effects on all outcomes.Ethics and disseminationEthical approval was obtained from all three participating sites. Primary and secondary outcome data will be submitted for publication in peer-reviewed journals and widely disseminated.Trial registration numberNCT01718977; Pre-results.Trial statusRecruitment for this study began on January 2013 and the first participant was randomized on April 2013. Recruitment stopped on October 2018.
