RESUMEN
OBJECTIVE: To determine the effectiveness of a web-based, direct-to-user transfer training program in improving transfer quality and maintaining improvements for up to 1 month after training as compared with a control group. DESIGN: Randomized controlled trial with participants randomized to an immediate intervention group (IIG) or waitlist control group (WLCG) that received the training after a 6-month delay. SETTING: Wherever the participants accessed the web-based training, likely the home environment. PARTICIPANTS: Convenience sample of full-time wheelchair users (N=72; IIG, n=34; WLCG, n=38 for between-group analysis, n=48 for combined within-group analysis) with spinal cord injury or disorder who were able to independently perform a lateral scoot transfer. INTERVENTIONS: Self-paced, web-based transfer training module. MAIN OUTCOME MEASURES: Transfer Assessment Instrument Questionnaire (TAI-Q) score at baseline, 1 month, and 6 months postbaseline (WLCG only), immediately posttraining, and 1 month posttraining. The TAI-Q is an 18-item self-assessment that covers several aspects of a quality transfer. RESULTS: The IIG significantly increased particpants' baseline TAI-Q score from 6.91±0.98 to 7.79±1.12 (P<.001) by 1 month posttraining. The WLCG also increased from baseline to the 1-month postbaseline assessment (from 6.52±1.13 to 7.00±1.09; P=.014), potentially from learning effects secondary to self-assessment with the TAI-Q. The extent of change over time did not differ significantly between the IIG and WLCG from baseline to 1 month (P=.169). However, significant improvements in TAI-Q scores were still evident after the training for the WLCG (P<.001). Those with a lower pretraining TAI-Q score and more shoulder pain were most likely to benefit from the training. CONCLUSIONS: Repeated TAI-Q self-assessments likely contributed to improved transfer quality, with web-based training having an additive effect. Wheelchair users are likely to benefit from transfer training and self-assessment of transfer quality in their home environments. This has the potential to decrease injury risk while avoiding barriers to in-person training.

OBJECTIVE: To evaluate the reliability, standard error of measurement, minimum detectable change, and item-level consistency of the Transfer Assessment Instrument (TAI) version 4.0 when used to evaluate transfer quality remotely. DESIGN: Participants transferred from their wheelchair to a mat table (transfer 1), repeated this after a 10-minute delay to assess intrarater reliability (transfer 2), and repeated this 1-2 days later to assess test-retest reliability (transfer 3). Each transfer was scored in person by 4 raters and asynchronously by a remote clinician rater. SETTING: 2017 National Veterans Wheelchair Games. PARTICIPANTS: Convenience sample of 44 full-time wheelchair users (N=44). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: TAI total score, subscores (wheelchair setup, body setup, flight/landing), and item scores (15 items). RESULTS: Moderate to excellent reliability was found when scoring remotely for TAI total and subscores for intrarater (intraclass correlation coefficient (ICC(3,1)=0.687-0.854), test-retest (ICC(3,1)=0.695-0.836), and interrater reliability (ICC(3,5)=0.746-0.962). Remote rater total score and flight/landing subscore were greater (indicating higher transfer quality) compared to the average in-person raters (P=.021 and P=.005, respectively). There were no differences between transfers 1-3 in remote rater scores. Item-level percentage agreement between the remote rater and in-person exceeded the 75% cutoff for clinical utility for all items. CONCLUSIONS: The TAI is a reliable outcome measure for assessing transfer technique remotely.

OBJECTIVE: To determine if functional measures of ambulation can be accurately classified using clinical measures; demographics; personal, psychosocial, and environmental factors; and limb accelerations (LAs) obtained during sleep among individuals with chronic, motor incomplete spinal cord injury (SCI) in an effort to guide future, longitudinal predictions models. DESIGN: Cross-sectional, 1-5 days of data collection. SETTING: Community-based data collection. PARTICIPANTS: Adults with chronic (>1 year), motor incomplete SCI (N=27). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Ambulatory ability based on the 10-m walk test (10MWT) or 6-minute walk test (6MWT) categorized as nonambulatory, household ambulator (0.01-0.44 m/s, 1-204 m), or community ambulator (>0.44 m/s, >204 m). A random forest model classified ambulatory ability using input features including clinical measures of strength, sensation, and spasticity; demographics; personal, psychosocial, and environmental factors including pain, environmental factors, health, social support, self-efficacy, resilience, and sleep quality; and LAs measured during sleep. Machine learning methods were used explicitly to avoid overfitting and minimize the possibility of biased results. RESULTS: The combination of LA, clinical, and demographic features resulted in the highest classification accuracies for both functional ambulation outcomes (10MWT=70.4%, 6MWT=81.5%). Adding LAs, personal, psychosocial, and environmental factors, or both increased the accuracy of classification compared with the clinical/demographic features alone. Clinical measures of strength and sensation (especially knee flexion strength), LA measures of movement smoothness, and presence of pain and comorbidities were among the most important features selected for the models. CONCLUSIONS: The addition of LA and personal, psychosocial, and environmental features increased functional ambulation classification accuracy in a population with incomplete SCI for whom improved prognosis for mobility outcomes is needed. These findings provide support for future longitudinal studies that use LA; personal, psychosocial, and environmental factors; and advanced analyses to improve clinical prediction rules for functional mobility outcomes.

OBJECTIVE: To investigate the frequency and consequences of wheelchair repairs, looking at the relationship to usage, components, out-of-pocket costs, number of days affecting the user, and factors associated with the need for repairs or consequences. DESIGN: Survey, cross-sectional. SETTING: Nine spinal cord injury (SCI) Model Systems centers. PARTICIPANTS: Wheelchair users with SCI (N=533). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Cost and incidence of wheelchair repairs and consequences and wheelchair usage within the past 6 months. RESULTS: A total of 310 participants (56%) reported repairs, 127 (42%) of whom experienced at least 1 adverse consequence lasting a median of 5 days (interquartile range [IQR], 2-17.3 days). Repair rates were highest for the seating system, electronics, and tires. Participants were most often stranded at home or forced to use a backup chair. Median out-of-pocket costs were $150 (IQR, $50-$620). Active users, based on type of mobility and terrain, experienced more repairs and consequences than less active users. Repairs were more common among those who were Black (odds ratio [OR], 2.42) or power wheelchair (PWC) users (OR, 1.84), whereas consequences were more common among those who were Black (OR, 2.27), PWC (OR, 2.08) or power assist users (OR, 2.76), and those who had public insurance (OR, 1.70). CONCLUSIONS: Wheelchair repairs continue to affect more than 50% of wheelchair users with significant financial and personal cost. High repair rates limited participation inside and outside of the home. Consequences lasted longer than 2 weeks for many and may be minimized by a working backup chair. Disparities exist based on participant and wheelchair factors; repairs and adverse consequences appear to hit those most vulnerable with the least financial resources. Costs may be a barrier to repair completion for some individuals. This ongoing problem of high repair rates and their associated effects requires action such as higher standards, access to quicker service, and better training of users on wheelchair maintenance and repair.

OBJECTIVE: To investigate the changes in total internet and mobile internet use over time and determine how demographic characteristics are related to changes in internet and mobile internet use among individuals with spinal cord injury (SCI). DESIGN: Cross-sectional analysis of a multicenter cohort study. SETTING: National SCI Database. PARTICIPANTS: Individuals with traumatic SCI with follow-up data collected between 2012 and 2018 (N=13,622). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Proportion of sample reporting internet use at all or through a mobile device over time and specifically in 2018. RESULTS: The proportion of internet users increased from 77.7% in 2012 to 88.1% in 2018. Older participants (P<.001); those with lower annual income (P<.001), less education (P<.001), non-White race or Hispanic ethnicity (P<.001), or motor incomplete tetraplegia (P=.004); and men (P=.035) were less likely to use the internet from 2012-2018. By 2018, there were no longer differences in internet use based on race and ethnicity (P=.290) or sex (P=.066). Mobile internet use increased each year (52.4% to 87.7% of internet users from 2012-2018), with a participant being 13.7 times more likely to use mobile internet in 2018 than 2012. Older age (P<.001), income <$50,000 (P<.001), high school diploma or less (P=.011), or non-Hispanic White race/ethnicity (P=.001) were associated with less mobile internet use over time. By 2018, there were no differences in mobile internet use by education (P=.430), and only participants with incomes >$75,000 per year had greater odds of mobile internet use (P=.016). CONCLUSIONS: Disparities associated with internet access are decreasing likely as a result of mobile device use. Increased internet access offers an important opportunity to provide educational and training materials to frequently overlooked groups of individuals with SCI.

OBJECTIVE: To assess the effectiveness of group wheelchair maintenance training and investigate participant characteristics associated with responsiveness to training. DESIGN: Randomized controlled trial with an immediate group and a waitlist control group (WLCG) who received the intervention after a 6-month delay. SETTING: Four Spinal Cord Injury Model Systems Centers. PARTICIPANTS: Manual (MWC; n=80) and power wheelchair (PWC; n=67) users with spinal cord injury (N=147). INTERVENTIONS: Two 90-minute structured wheelchair maintenance training program classes with 12-20 people per class and separate classes for MWC and PWC users. Each class included in-person hands-on demonstrations and practice of wheelchair maintenance. MAIN OUTCOME MEASURES: Separate analysis was completed for MWC and PWC users using the Wheelchair Maintenance Training Questionnaire (WMT-Q) capacity (ability to complete), performance (frequency of completion) and knowledge at baseline, 1 month, 6 months, 6 months pretraining (WLCG only), and 1 year (immediate only). RESULTS: After the intervention, participants in both the immediate and WLCG improved in maintenance capacity (MWC and PWC, P<.001) and performance (MWC and PWC, P<.001) with training. Only PWC users improved knowledge of wheelchair maintenance (P<.001). For both WLCGs (MWC and PWC), there was no difference between the 6-month pretraining time point and baseline. MWC users who responded to training had lower WMT-Q scores for all domains, whereas this was only the case for knowledge for PWC users. CONCLUSIONS: Group wheelchair skills training is effective at improving capacity to complete maintenance and performance of maintenance activities for MWC and PWC users, even in a cohort of experienced wheelchair users. For MWC users, improvements were tied to lower WMT-Q scores at baseline, whereas PWC users improved in capacity and performance independent of baseline score. Delivering this training in a structured group format has a lower cost, which might improve adoption into clinical practice.

OBJECTIVE: To test the hypotheses that remote training improves trainer confidence and when these trainers train others the capacity and confidence of the trainees improves. DESIGN: Cohort study with pre- vs posttraining comparisons. SETTING: Four spinal cord injury model systems centers. PARTICIPANTS: Convenience sample of 7 clinician trainers and 19 able-bodied trainees (N=26). INTERVENTIONS: Part 1 focused on trainer skill acquisition with self-study of the Wheelchair Skills Program Manual and instructional videos focused on motor learning, spotting, and 10 intermediate and advanced wheelchair skills. Trainers practiced in pairs, receiving asynchronous feedback on video recordings from a remote instructor. Part 2 included additional video modules targeted at "how to" assess and train others in 4 wheelchair skills: gets over obstacle, ascends low curb, ascends high curb with caregiver assistance, and performs stationary wheelie. Upon completion, the trainers each provided 1:1 in-person training for 2-3 trainees. MAIN OUTCOME MEASURES: Trainer confidence was assessed using the Self-Efficacy on Assessing, Training, and Spotting Test for Manual Wheelchairs. Trainee capacity ("Can you do it?") and confidence ("How confident are you?") were evaluated using the Wheelchair Skills Test Questionnaire (WST-Q). RESULTS: Trainer confidence increased for assessment (P=.003) and training (P=.002) but not spotting (P=.056). Trainee 4-item median (interquartile range) WST-Q scores significantly increased with training for capacity (13% [6-31] to 88% [75-88], P<.001) and confidence (13% [0-31] to 88% [81-100], P<.001). CONCLUSIONS: Remote training improves trainers' confidence with respect to wheelchair skills testing and training and the wheelchair skills capacity and confidence of their trainees.

BACKGROUND: To evaluate the relationship between measures of neuromuscular impairment and limb accelerations (LA) collected during sleep among individuals with chronic spinal cord injury (SCI) to provide evidence of construct and concurrent validity for LA as a clinically meaningful measure. METHODS: The strength (lower extremity motor score), sensation (summed lower limb light touch scores), and spasticity (categorized lower limb Modified Ashworth Scale) were measured from 40 adults with chronic (≥ 1 year) SCI. Demographics, pain, sleep quality, and other covariate or confounding factors were measured using self-report questionnaires. Each participant then wore ActiGraph GT9X Link accelerometers on their ankles and wrist continuously for 1-5 days to measure LA from movements during sleep. Regression models with built-in feature selection were used to determine the most relevant LA features and the association to each measure of impairment. RESULTS: LA features were related to measures of impairment with models explaining 69% and 73% of the variance (R²) in strength and sensation, respectively, and correctly classifying 81.6% (F1-score = 0.814) of the participants into spasticity categories. The most commonly selected LA features included measures of power and frequency (frequency domain), movement direction (correlation between axes), consistency between movements (relation to recent movements), and wavelet energy (signal characteristics). Rolling speed (change in angle of inclination) and movement smoothness (median crossings) were uniquely associated with strength. When LA features were included, an increase of 72% and 222% of the variance was explained for strength and sensation scores, respectively, and there was a 34% increase in spasticity classification accuracy compared to models containing only covariate features such as demographics, sleep quality, and pain. CONCLUSION: LA features have shown evidence of having construct and concurrent validity, thus demonstrating that LA are a clinically-relevant measure related to lower limb strength, sensation, and spasticity after SCI. LA may be useful as a more detailed measure of impairment for applications such as clinical prediction models for ambulation.

Motor commands for the arm and hand generally arise from the contralateral motor cortex, where most of the relevant corticospinal tract originates. However, the ipsilateral motor cortex shows activity related to arm movement despite the lack of direct connections. The extent to which the activity related to ipsilateral movement is independent from that related to contralateral movement is unclear based on conflicting conclusions in prior work. Here we investigate bilateral arm and hand movement tasks completed by two human subjects with intracortical microelectrode arrays implanted in the left hand and arm area of the motor cortex. Neural activity was recorded while they attempted to perform arm and hand movements in a virtual environment. This enabled us to quantify the strength and independence of motor cortical activity related to continuous movements of each arm. We also investigated the subjects' ability to control both arms through a brain-computer interface. Through a number of experiments, we found that ipsilateral arm movement was represented independently of, but more weakly than, contralateral arm movement. However, the representation of grasping was correlated between the two hands. This difference between hand and arm representation was unexpected and poses new questions about the different ways the motor cortex controls the hands and arms.

The growing field of regenerative rehabilitation has great potential to improve clinical outcomes for individuals with disabilities. However, the science to elucidate the specific biological underpinnings of regenerative rehabilitation-based approaches is still in its infancy and critical questions regarding clinical translation and implementation still exist. In a recent roundtable discussion from International Consortium for Regenerative Rehabilitation stakeholders, key challenges to progress in the field were identified. The goal of this article is to summarize those discussions and to initiate a broader discussion among clinicians and scientists across the fields of regenerative medicine and rehabilitation science to ultimately progress regenerative rehabilitation from an emerging field to an established interdisciplinary one. Strategies and case studies from consortium institutions-including interdisciplinary research centers, formalized courses, degree programs, international symposia, and collaborative grants-are presented. We propose that these strategic directions have the potential to engage and train clinical practitioners and basic scientists, transform clinical practice, and, ultimately, optimize patient outcomes.

STUDY DESIGN: A quasi-experimental, pretest-posttest design. OBJECTIVES: To identify acute changes in the supraspinatus and biceps tendon following fatiguing wheelchair propulsion and to associate tendon changes with risk factors associated with shoulder pain in persons with spinal cord injury (SCI). SETTING: Biomechanical laboratory Swiss Paraplegic Research. METHODS: A population-based sample of 50 wheelchair users with SCI at lesion level T2 or below participated. Fatigue was measured by using the rate of perceived exertion and heart rate. Linear regression techniques were used to assess the association between the dependent and independent variables. Dependent variables included absolute differences in supraspinatus and biceps tendon thickness, contrast, and echogenicity ratio assessed with ultrasound before and after a fatiguing wheelchair propulsion intervention. Independent variables included susceptibility to fatigue (Yes/No), the acromio-humeral distance, sex, time since injury, activity levels, and body weight. RESULTS: A reduction in supraspinatus tendon thickness after fatiguing wheelchair propulsion (-1.39 mm; 95% CI: -2.28; -0.51) was identified after controlling for all potential confounders. Females who fatigued (n = 4) displayed a greater reduction in supraspinatus tendon thickness as compared with those who did not fatigue (n = 7). In contrast, higher body weight was associated with an increase in supraspinatus tendon thickness and a greater acromio-humeral distance before the intervention was associated with an increase in biceps tendon thickness. CONCLUSIONS: Acute changes in the supraspinatus and biceps tendon after fatiguing wheelchair propulsion may explain the high prevalence of tendon injuries in this population. Future research should determine the consequences of tendon changes and its relationship to tendinopathy.

Motor output maps within primary motor cortex are widely distributed and modified by motor skill learning and neurological injury. Functions that these maps represent after spinal cord injury remain debatable. Moreover, the pattern of reorganization and whether it supports recovery of compromised motor function is not well understood. A deeper understanding of the pathophysiological mechanisms of motor dysfunction after spinal cord injury is necessary to develop and optimize repair strategies. There are three purposes for this review. The first is to synthesize available research on spontaneous reorganization with primary motor cortex following spinal cord injury. The second is to draw on existing evidence from the motor skill learning and brain injury literature to interpret the form and purpose of motor maps. The third purpose is to account for the existing research on intervention-induced reorganization of primary motor cortex following spinal cord injury. We conclude with directions for future work, emphasizing the need for multi-modal investigations that construct maps with both neuroimaging and non-invasive stimulation methods to derive a cohesive understanding of the effects of spinal cord injury on reorganization within primary motor cortex.

OBJECTIVES: In a sample of wheelchair users with spinal cord injury (SCI), the objectives were to investigate which participant characteristics are associated with greater perceived discrimination in the health care setting, and how such discrimination relates to health outcomes of pain and depressive symptoms. DESIGN: Survey, cross-sectional. SETTING: Spinal Cord Injury Model Systems (SCIMS) Center. PARTICIPANTS: Full-time wheelchair users with SCI from 9 SCIMS centers (N=410), with data collected between 2011 and 2016. INTERVENTIONS: N/A. MAIN OUTCOMES: A 7-item questionnaire inquiring about perceived discrimination by hospital staff, self-reported pain severity over the past month using a 0-10 Numeric Rating Scale, and depressive symptoms using the 2-question Patient Health Questionnaire screener. RESULTS: Participants who were black or from the lowest income group were more likely to report experiencing more discrimination than those who were white or from the highest income group, respectively (incidence rate ratio=2.2-2.6, P<.01). Those who reported more perceived discrimination had greater risk of severe pain compared to no pain (relative risk [RR]=1.11; 95% confidence interval [95% CI], 1.01-1.23; P<.05), mild depressive symptoms (RR=1.09; 95% CI, 1.02-1.17; P<.05), and severe depressive symptoms (RR=1.12; 95% CI, 1.04-1.21; P<.05) compared to no symptoms. CONCLUSIONS: Wheelchair users with SCI who were from more disadvantaged groups (black, lower income levels) reported experiencing more discrimination in their health care setting. Furthermore, those who reported more discrimination were more likely to report worse mental and physical health outcomes. Attempts to reduce discrimination in health care settings may lead to better outcomes for people with SCI. These observations were correlational and not causal; a prospective analysis is necessary to prove causation. Future investigations should further explore the effect of discrimination on the many facets of living with an SCI.

OBJECTIVES: To investigate the relation of gait training (GT) during inpatient rehabilitation (IPR) to outcomes of people with traumatic spinal cord injury (SCI). DESIGN: Prospective observational study using the SCIRehab database. SETTING: Six IPR facilities. PARTICIPANTS: Patients with new SCI (N=1376) receiving initial rehabilitation. INTERVENTIONS: Patients were divided into groups consisting of those who did and did not receive GT. Patients were further subdivided based on their primary mode of mobility as measured by the FIM. MAIN OUTCOME MEASURES: Pain rating scales, Patient Health Questionnaire Mood Subscale, Satisfaction With Life Scale, and Craig Handicap Assessment and Reporting Technique (CHART). RESULTS: Nearly 58% of all patients received GT, including 33.3% of patients who were primarily using a wheelchair 1 year after discharge from IPR. Those who used a wheelchair and received GT, received significantly less transfer and wheeled mobility training (P<.001). CHART physical independence (P=.002), mobility (P=.024), and occupation (P=.003) scores were significantly worse in patients who used a wheelchair at 1 year and received GT, compared with those who used a wheelchair and did not receive GT in IPR. Older age was also a significant predictor of worse participation as measured by the CHART. CONCLUSIONS: A significant percentage of individuals who are not likely to become functional ambulators are spending portions of their IPR stays performing GT, which is associated with less time allotted for other functional interventions. GT in IPR was also associated with participation deficits at 1 year for those who used a wheelchair, implying the potential consequences of opportunity costs, pain, and psychological difficulties of receiving unsuccessful GT. Clinicians should consider these data when deciding to implement GT during initial IPR.

OBJECTIVES: To determine the efficacy of a web-based transfer training module at improving transfer technique across 3 groups: web-based training, in-person training (current standard of practice), and a waitlist control group (WLCG); and secondarily, to determine subject factors that can be used to predict improvements in transfer ability after training. DESIGN: Randomized controlled trials. SETTING: Summer and winter sporting events for disabled veterans. PARTICIPANTS: A convenience sample (N=71) of manual and power wheelchair users who could transfer independently. INTERVENTIONS: An individualized, in-person transfer training session or a web-based transfer training module. The WLCG received the web training at their follow-up visit. MAIN OUTCOME MEASURE: Transfer Assessment Instrument (TAI) part 1 score was used to assess transfers at baseline, skill acquisition immediately posttraining, and skill retention after a 1- to 2-day follow-up period. RESULTS: The in-person and web-based training groups improved their median (interquartile range) TAI scores from 7.98 (7.18-8.46) to 9.13 (8.57-9.58; P<.01), and from 7.14 (6.15-7.86) to 9.23 (8.46-9.82; P<.01), respectively, compared with the WLCG that had a median score of 7.69 for both assessments (baseline, 6.15-8.46; follow-up control, 5.83-8.46). Participants retained improvements at follow-up (P>.05). A lower initial TAI score was found to be the only significant predictor of a larger percent change in TAI score after receiving training. CONCLUSIONS: Transfer training can improve technique with changes retained within a short follow-up window, even among experienced wheelchair users. Web-based transfer training demonstrated comparable improvements to in-person training. With almost half of the United States population consulting online resources before a health care professional, web-based training may be an effective method to increase knowledge translation.

OBJECTIVES: To evaluate the relation between wheelchair breakdowns, their immediate consequences, and secondary health complications after spinal cord injury. "Immediate consequences" occur when part of a wheelchair breaks and leaves an individual stranded or injured, or causes him or her to miss medical appointments, work, or school. DESIGN: Survey, cross-sectional. SETTING: Spinal Cord Injury Model Systems Centers. PARTICIPANTS: Full-time wheelchair users (N=771) with SCI from 9 Spinal Cord Injury Model Systems Centers, with data collected between 2011 and 2016. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Incidence of self-reported wheelchair breakdowns within the past 6 months that did or did not result in immediate consequences (ie, injury, being stranded, missing a medical appointment, or an inability to attend school/work); self-perceived health status scale; pain severity numerical rating scale; rehospitalizations; and self-reported pressure injury development within the past 12 months. RESULTS: A total of 610 participants with complete data sets were included in the analyses. When compared to those who reported no breakdowns, participants who reported 1 or more immediate consequences had worse secondary complications: higher self-perceived health status and pain scores (partial -η2=.009-.012, P<.05), and higher odds of rehospitalization (odds ratio: 1.86, P<.05) and pressure injury development (odds ratio: 1.73, P<.05). Secondary health complications were not different in those who reported no immediate consequences compared to those who reported no breakdown. CONCLUSIONS: Wheelchair breakdowns that resulted in injury, being stranded, missing medical appointments, and/or an inability to attend work/school appear to have far-reaching impacts on health and secondary injury. Preventing wheelchair breakdowns, through either better maintenance or manufacturing, may be a means of decreasing secondary disability.

STUDY DESIGN: This is a focused review article. OBJECTIVES: To identify important concepts in lower extremity (LE) assessment with a focus on locomotor outcomes and provide guidance on how existing outcome measurement tools may be best used to assess experimental therapies in spinal cord injury (SCI). The emphasis lies on LE outcomes in individuals with complete and incomplete SCI in Phase II-III trials. METHODS: This review includes a summary of topics discussed during a workshop focusing on LE function in SCI, conceptual discussion of corresponding outcome measures and additional focused literature review. RESULTS: There are a number of sensitive, accurate, and responsive outcome tools measuring both quantitative and qualitative aspects of LE function. However, in trials with individuals with very acute injuries, a baseline assessment of the primary (or secondary) LE outcome measure is often not feasible. CONCLUSION: There is no single outcome measure to assess all individuals with SCI that can be used to monitor changes in LE function regardless of severity and level of injury. Surrogate markers have to be used to assess LE function in individuals with severe SCI. However, it is generally agreed that a direct measurement of the performance for an appropriate functional activity supersedes any surrogate marker. LE assessments have to be refined so they can be used across all time points after SCI, regardless of the level or severity of spinal injury. SPONSORS: Craig H. Neilsen Foundation, Spinal Cord Outcomes Partnership Endeavor.

OBJECTIVES: To examine (1) differences in quality-of-life scores for groups based on transitions in locomotion status at 1, 5, and 10 years postdischarge in a sample of people with spinal cord injury (SCI); and (2) whether demographic factors and transitions in locomotion status can predict quality-of-life measures at these time points. DESIGN: Retrospective case study of the National SCI Database. SETTING: Model SCI Systems Centers. PARTICIPANTS: Individuals with SCI (N=10,190) from 21 SCI Model Systems Centers, identified through the National SCI Model Systems Centers database between the years 1985 and 2012. Subjects had FIM (locomotion mode) data at discharge and at least 1 of the following: 1, 5, or 10 years postdischarge. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: FIM-locomotion mode; Severity of Depression Scale; Satisfaction With Life Scale; and Craig Handicap Assessment and Reporting Technique. RESULTS: Participants who transitioned from ambulation to wheelchair use reported lower participation and life satisfaction, and higher depression levels (P<.05) than those who maintained their ambulatory status. Participants who transitioned from ambulation to wheelchair use reported higher depression levels (P<.05) and no difference for participation (P>.05) or life satisfaction (P>.05) compared with those who transitioned from wheelchair to ambulation. Demographic factors and locomotion transitions predicted quality-of-life scores at all time points (P<.05). CONCLUSIONS: The results of this study indicate that transitioning from ambulation to wheelchair use can negatively impact psychosocial health 10 years after SCI. Clinicians should be aware of this when deciding on ambulation training. Further work to characterize who may be at risk for these transitions is needed.

OBJECTIVES: To assess in Veterans with spinal cord injury (SCI) or amputated limb (AL) the following: (1) patient demographics, medical factors, cultural and psychosocial characteristic by race; (2) wheelchair quality by race; and (3) the independent associations of patient race and the other factors with wheelchair quality. DESIGN: Cross-sectional cohort study. SETTING: Three Department of Veterans Affairs (VA) medical centers affiliated with academic medical centers. PARTICIPANTS: Eligible participants were Veterans with SCI or ALs (N=516); 482 of them completed the interview. Analyses were restricted to white and African American participants. Because there was no variation in wheelchair quality among AL patients (n=42), they were excluded from all but descriptive analyses, leading to a final sample size of 421. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Wheelchair quality as defined by the Medicare Healthcare Common Procedure Coding System. RESULTS: We found race differences in many of our variables, but not in quality for manual (odds ratio [OR]=.67; 95% confidence interval [CI], .33-1.36) or power (OR=.82; 95% CI, .51-1.34) wheelchairs. Several factors including age (OR=.96; 95% CI, .93-.99) and income (OR=3.78; 95% CI, 1.43-9.97) were associated with wheelchair quality. There were no significant associations of cultural or psychosocial factors with wheelchair quality. CONCLUSIONS: Although there were no racial differences in wheelchair quality, we found a significant association of older age and lower income with poorer wheelchair quality among Veterans. Efforts are needed to raise awareness of such disparities among VA wheelchair providers and to take steps to eliminate these disparities in prescription practice across VA sites.
