Patients with chronic low back pain (CLBP) exhibit remodelling of the lumbar soft tissues such as muscle fatty infiltrations (MFI) and fibrosis of the lumbar multifidus (LuM) muscles, thickness changes of the thoracolumbar fascia (TLF) and perimuscular connective tissues (PMCT) surrounding the abdominal lateral wall muscles. Rehabilitative ultrasound imaging (RUSI) parameters such as thickness and echogenicity are sensitive to this remodelling. This experimental laboratory study aimed to explore whether these RUSI parameters (LuM echogenicity and fascia thicknesses), hereafter called dependent variables (DV) were linked to independent variables (IV) such as (1) other RUSI parameters (trunk muscle thickness and activation) and (2) physical and psychological measures. RUSI measures, as well as a clinical examination comprising physical tests and psychological questionnaires, were collected from 70 participants with LBP. The following RUSI dependent variables (RUSI-DV), measures of passive tissues were performed bilaterally: (1) LuM echogenicity (MFI/fibrosis) at three vertebral levels (L3/L4, L4/L5 and L5/S1); (2) TLF posterior layer thickness, and (3) PMCT thickness of the fasciae between subcutaneous tissue thickness (STT) and external oblique (PMCT

Introduction: Achilles tendinopathy (AT) is a chronic musculoskeletal pathology best evaluated by ultrasound imaging. This cross-sectional study aimed at better understanding the relationship between musculoskeletal ultrasound biomarkers (MUBs) of Achilles tendon and localized pain, ankle flexibility, ankle strength, and functional abilities.Method: Forty-one participants with unilateral midportion chronic AT had their tendon images analyzed bilaterally in the longitudinal and transverse planes. The Victorian Institute of Sport Assessment-Achilles questionnaire (VISA-A) and Lower Extremity Functional Scale (LEFS) assessed pain and function, respectively, during standing and walking-related activities. Ankle flexibility was evaluated by weight-bearing lunge tests, while ankle isometric peak strength was measured using an instrumented dynamometer. Achilles tendon ultrasonographic images were analyzed using geometric (thickness), composition (echogenicity), and texture (homogeneity) MUBs. Discriminative validity was evaluated using paired Student's t-tests to compare MUBs between symptomatic and asymptomatic sides. Predictive validity was evaluated by computing the Pearson product-moment correlations coefficient between MUBs and pain, ankle flexibility, ankle strength, and function.Results: Significant differences were found in MUBs between the symptomatic and asymptomatic sides, confirming the discriminative validity of the selected MUBs. On the symptomatic side, thickness was found 29.9% higher (p < 0.001), echogenicity 9.6% lower (p < 0.001), and homogeneity 3.8% higher (p = 0.001) when compared with the asymptomatic side. However, predictive validity was scarcely confirmed, as most of the correlation coefficients were found negligible for the associations investigated between MUBs with localized pain, ankle flexibility, strength, and function. Only 14 statistically significant low to moderate associations were found, with negative and positive correlations ranging between −0.31 and −0.55 and between 0.34 and 0.54, respectively.Discussion: Musculoskeletal ultrasound biomarkers have a clinical utility in visualizing in vivo tendon integrity and diagnosing AT. MUBs should be valued as part of a comprehensive neuro-musculoskeletal assessment as they complement pain, flexibility, strength, and function measures. Altogether, they may inform the development and monitoring of a personalized rehabilitation treatment plan.

Context/Objective: The Spinal Cord Injury (SCI) Standing and Walking Assessment Tool (SWAT) combines stages of walking recovery with measures of balance and walking. It standardizes the timing and content of walking assessment in inpatient rehabilitation. The study aims were: (1) Evaluate the content validity of the SWAT stages of walking recovery, and (2) Understand physical therapists' (PTs) experiences using the SWAT to gauge acceptance, implementation and impact. Design: Qualitative, exploratory study. Setting: Nine Canadian rehabilitation hospitals. Participants: Thirty-four PTs who had used the SWAT ≥10 times. Interventions: Seven focus group meetings were completed. Semi-structured questions queried the content, order and spacing of SWAT stages, and current SWAT use (i.e. processes, challenges, facilitators, impact on practice). Meetings were audio-recorded and transcribed. Themes and categories were derived through a conventional content analysis. Outcome Measure: Not applicable. Results: PTs agreed with the ordering and content of the SWAT stages, but reported unequal spacing between stages. Three themes related to PTs’ use of the SWAT were identified: (1) Variable process: SWAT implementation varied across sites, PTs and patients. (2) Implementation challenges: unfamiliarity of the SWAT, lack of time, not required by place of work, and patients who are outliers or have poor gait quality. (3) Potential to influence clinical decision-making: the SWAT did not influence clinical decisions, but PTs recognized the potential of the tool to do so. Conclusions: Content validity of the SWAT stages was supported and implementation challenges identified. Variability in SWAT implementation may reflect the heterogeneity and person-centeredness of SCI rehabilitation.

CONTEXT: Endocrine-metabolic disease (EMD) is associated with functional disability, social isolation, hospitalization and even death in individuals living with a chronic spinal cord injury (SCI). There is currently very low-quality evidence that rehabilitation interventions can reduce EMD risk during chronic SCI. Non-randomized trials and alternative study designs are excluded from traditional knowledge synthesis. OBJECTIVE: To characterize evidence from level 3–4 studies evaluating rehabilitation interventions for their effectiveness to improve EMD risk in community-dwelling adults with chronic SCI. METHODS: Systematic searches of MEDLINE PubMed, EMBASE Ovid, CINAHL, Cochrane Database of Systematic Reviews, and PsychInfo were completed. All longitudinal trials, prospective cohort, case–control studies, and case series evaluating the effectiveness of rehabilitation/therapeutic interventions to modify/associate with EMD outcomes in adults with chronic SCI were eligible. Two authors independently selected studies and abstracted data. Mean changes from baseline were reported for EMD outcomes. The Downs and Black Checklist was used to rate evidence quality. RESULTS: Of 489 articles identified, 44 articles (N = 842) were eligible for inclusion. Individual studies reported statistically significant effects of electrical stimulation-assisted training on lower-extremity bone outcomes, and the combined effects of exercise and dietary interventions to improve body composition and cardiometabolic biomarkers (lipid profiles, glucose regulation). In contrast, there were also reports of no clinically important changes in EMD outcomes, suggesting lower quality evidence (study bias, inconsistent findings). CONCLUSION: Longitudinal multicentre pragmatic studies involving longer-term exercise and dietary intervention and follow-up periods are needed to fully understand the impact of these rehabilitation approaches to mitigate EMD risk. Our broad evaluation of prospective cohort and case–control studies provides new perspectives on alternative study designs, a multi-impairment paradigm approach of studying EMD outcomes, and knowledge gaps related to SCI rehabilitation.

BackgroundIn wheelchair users with a chronic spinal cord injury (WUSCI), prolonged nonactive sitting time and reduced physical activity—typically linked to this mode of mobility—contribute to the development or exacerbation of cardiorespiratory, musculoskeletal, and endocrine-metabolic health complications that are often linked to increased risks of chronic pain or psychological morbidity. Limited evidence suggests that engaging in a walking program with a wearable robotic exoskeleton may be a promising physical activity intervention to counter these detrimental health effects.ObjectiveThis study’s overall goals are as follows: (1) to determine the effects of a 16-week wearable robotic exoskeleton–assisted walking program on organic systems, functional capacities, and multifaceted psychosocial factors and (2) to determine self-reported satisfaction and perspectives with regard to the intervention and the device.MethodsA total of 20 WUSCI, who have had their injuries for more than 18 months, will complete an overground wearable robotic exoskeleton–assisted walking program (34 sessions; 60 min/session) supervised by a physiotherapist over a 16-week period (one to three sessions/week). Data will be collected 1 month prior to the program, at the beginning, and at the end as well as 2 months after completing the program. Assessments will characterize sociodemographic characteristics; anthropometric parameters; sensorimotor impairments; pain; lower extremity range of motion and spasticity; wheelchair abilities; cardiorespiratory fitness; upper extremity strength; bone architecture and mineral density at the femur, tibia, and radius; total and regional body composition; health-related quality of life; and psychological health. Interviews and an online questionnaire will be conducted to measure users’ satisfaction levels and perspectives at the end of the program. Differences across measurement times will be verified using appropriate parametric or nonparametric analyses of variance for repeated measures.ResultsThis study is currently underway with active recruitment in Montréal, Québec, Canada. Results are expected in the spring of 2021.ConclusionsThe results from this study will be essential to guide the development, implementation, and evaluation of future evidence-based wearable robotic exoskeleton–assisted walking programs offered in the community, and to initiate a reflection regarding the use of wearable robotic exoskeletons during initial rehabilitation following a spinal cord injury.Trial RegistrationClinicalTrials.gov NCT03989752; https://clinicaltrials.gov/ct2/show/NCT03989752International Registered Report Identifier (IRRID)DERR1-10.2196/19251

Background Many wheelchair users adopt a sedentary lifestyle, which results in progressive physical deconditioning with increased risk of musculoskeletal, cardiovascular and endocrine/metabolic morbidity and mortality. Engaging in a walking program with an overground robotic exoskeleton may be an effective strategy for mitigating these potential negative health consequences and optimizing fitness in this population. However, additional research is warranted to inform the development of adapted physical activity programs incorporating this technology. Objectives To determine cardiorespiratory demands during sitting, standing and overground walking with a robotic exoskeleton and to verify whether such overground walking results in at least moderate-intensity physical exercise. Methods We enrolled 13 long-term wheelchair users with complete motor spinal cord injury in a walking program with an overground robotic exoskeleton. Cardiorespiratory measures and rate of perceived exertion (RPE) were recorded by using a portable gas analyzer system during sitting, standing and four 10 m walking tasks with the robotic exoskeleton. Each participant also performed an arm crank ergometer test to determine maximal cardiorespiratory ability (i.e., peak heart rate and O 2 uptake [HR peak , VO 2peak ]). Results Cardiorespiratory measures increased by a range of 9%–35% from sitting to standing and further increased by 22%–52% from standing to walking with the robotic exoskeleton. During walking, median oxygen cost (O 2Walking ), relative HR (%HR peak ), relative O 2 consumption (%VO 2peak ) and respiratory exchange ratio (RER) reached 0.29 mL/kg/m, 82.9%, 41.8% and 0.9, respectively, whereas median RPE reached 3.2/10. O 2Walking was moderately influenced by total number of sessions and steps taken with the robotic exoskeleton since the start of the walking program. Conclusion Overground walking with the robotic exoskeleton over a short distance allowed wheelchair users to achieve a moderate-intensity level of exercise. Hence, an overground locomotor training program with a robotic exoskeleton may have cardiorespiratory health benefits in the population studied.

Cardiorespiratory fitness training is commonly provided to manual wheelchair users (MWUs) in rehabilitation and physical activity programs, emphasizing the need for a reliable task-specific incremental wheelchair propulsion test.Quantifying test-retest reliability and minimal detectable change (MDC) of key cardiorespiratory fitness measures following performance of a newly developed continuous treadmill-based wheelchair propulsion test (WPTTwenty-five MWUs completed the WPTExcellent test-retest reliability was reached for almost all outcome measures (ICC=0.91-0.76), except for RERThe WPT

Background Cardiorespiratory fitness assessment and training among manual wheelchair (MW) users are predominantly done with an arm-crank ergometer. However, arm-crank ergometer biomechanics differ substantially from MW propulsion biomechanics. This study aimed to quantify cardiorespiratory responses resulting from speed and slope increments during MW propulsion on a motorized treadmill and to calculate a predictive equation based on speed and slope for estimating peak oxygen uptake (VO 2peak ) in MW users. Methods In total, 17 long-term MW users completed 12 MW propulsion periods (PP), each lasting 2 min, on a motorized treadmill, in a random order. Each PP was separated by a 2-min rest. PPs were characterized by a combination of 3 speeds (0.6, 0.8 and 1.0 m/s) and 4 slopes (0°, 2.7°, 3.6° and 4.8°). Six key cardiorespiratory outcome measures (VO 2 , heart rate, respiratory rate, minute ventilation and tidal volume) were recorded by using a gas-exchange analysis system. Rate of perceived exertion (RPE) was measured by using the modified 10-point Borg scale after each PP. Results For the 14 participants who completed the test, cardiorespiratory responses increased in response to speed and/or slope increments, except those recorded between the 3.6 o and 4.8 o slope, for which most outcome measures were comparable. The RPE was positively associated with cardiorespiratory response ( r s ≥ 0.85). A VO 2 predictive equation ( R 2 = 99.7%) based on speed and slope for each PP was computed. This equation informed the development of a future testing protocol to linearly increase VO 2 via 1-min stages during treadmill MW propulsion. Conclusions Increasing speed and slope while propelling a MW on a motorized treadmill increases cardiorespiratory response along with RPE. RPE can be used to easily and accurately monitor cardiorespiratory responses during MW exercise. The VO 2 can be predicted to some extent by speed and slope during MW propulsion. A testing protocol is proposed to assess cardiorespiratory fitness during motorized MW propulsion.

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.

Objective To examine the effect on body composition and bone mineral density of locomotor training using a robotic exoskeleton in individuals with spinal cord injury. Study design Interventional study. Subjects/methods Five adults with a non-progressive traumatic complete sensorimotor spinal cord injury who were using a wheelchair as a primary mode of mobility. Participants performed a personalized 6-week progressive locomotor training programme using a robotic exoskeleton 3 times/week for up to 60 min. Body composition measures were determined using dual energy X-ray absorptiometry and peripheral quantitative computed tomography. Results A significant increase in leg and appendicular lean body mass and a decrease in total, leg and appendicular fat mass was observed after the intervention. Furthermore, the calf muscle cross-sectional area increased significantly after the intervention. Finally, although not statistically significant, there was an increase of 14.5% in bone mineral density of the tibia, which may be clinically significant. A decrease of > 5 % was also noted for subcutaneous adipose tissue and intramuscular adipose tissue. Conclusion Locomotor training using a robotic exoskeleton appears to be associated with improvements in body composition and, potentially, bone health.

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 The population with a spinal cord injury (SCI) largely remains inactive following discharge from rehabilitation despite evidence on the benefits of physical activity. These individuals need to develop skills to self-manage their condition in order to prevent secondary comorbidities and rehospitalization. A Web-based physical activity portal can address this need. Few Web-based interventions incorporate theoretical frameworks, behavior change techniques, and modes of delivery into their design. CONCLUSIONS This study highlights features of an online self-management platform that can provide individuals with an SCI the motivation and volition to engage in physical activity. These findings will inform the design of a Web-based self-management physical activity portal to increase physical activity adherence and behavior change. METHODS An interpretative phenomenology methodology and participatory design, along with an integrated knowledge translation approach, were used to conduct this study. Convenience sampling was used to recruit individuals with an SCI living in the community, who were either interested or already engaging in physical activity, and HCPs working with individuals with an SCI, from three city-based rehabilitation sites. Individual 1-hour sessions involving navigation of an existing website and a semistructured interview were conducted with all participants. Individuals with an SCI completed a demographics questionnaire prior to the individual sessions, while demographic information of the HCPs was collected during their interviews. Additionally, all participants were asked a question on their intention to use or recommend a portal. An in-depth thematic analysis was used to derive themes from participants’ responses. OBJECTIVE This study aimed to identify the preferred features of a Web-based self-management physical activity portal through stakeholder engagement with individuals with a spinal cord injury and health care professionals (HCPs). RESULTS Thirteen individuals with an SCI and nine HCPs participated in the study. Five core themes emerged: (1) knowledge: guidance and barrier management; (2) possibility of achievement: the risks and benefits of physical activity and modelling; (3) self-regulation strategies: action planning, goal setting, tracking, rewards, and reminders; (4) interactivity: peers and professionals; and (5) format: appearance, language, and ease of use. The mean (median) ratings of the likelihood of promoting and using a Web-based portal tailored to individuals’ needs were 9.00 (8.78) and 7.75 (7.88) for HCPs and individuals with an SCI, respectively.

The prognosis for patients with a complete traumatic spinal cord injury (SCI) is generally poor. It is unclear whether some subgroups of patients with a complete traumatic SCI could benefit from early surgical decompression of the spinal cord. The objectives of this study were: (1) to compare the effect of early and late surgical decompression on neurological recovery in complete traumatic SCI and (2) to assess whether the impact of surgical timing is different in patients with cervical or thoracolumbar SCI. A prospective cohort study was followed in a single Level 1 Trauma Center specializing in SCI care. All consecutive patients who sustained a traumatic SCI and were referred between 2010 and 2013 were screened for eligibility. Neurological status was assessed systematically using the American Spinal Injury Association impairment scale (AIS) at arrival to the trauma center and at rehabilitation discharge. Patients operated within 24 h of the trauma were compared with patients operated later than 24 h after the trauma. Potential confounders such as age, Injury Severity Score (ISS), smoking history, body mass index (BMI), Glasgow Coma Scale (GCS) score, and duration of follow-up were recorded. Fifty-three patients with complete SCI were included in the study: 33 thoracolumbar and 20 cervical SCIs. The 38 patients operated24 h were generally younger than the 15 patients operated ≥ 24 h (p = 0.049). Overall, 28% (15/53) of complete SCI had improvement in AIS: 34% (13/38) who were operated24 h and 13% (2/15) who were operated ≥ 24 h (p = 0.182). Sixty-four percent (9/14) of cervical complete SCI operated24 h had improvement in AIS as opposed to none in the subgroup of six complete cervical SCI operated ≥ 24 h (p = 0.008). Surgical decompression within 24 h in complete SCI may optimize neurological recovery, especially in patients with cervical SCI.

Despite limited scientific evidence, there is an increasing interest in soft robotic gloves to optimize hand- and finger-related functional abilities following a neurological event. This review maps evidence on the effects and effectiveness of soft robotic gloves for hand rehabilitation and, whenever possible, patients’ satisfaction. A systematized search of the literature was conducted using keywords structured around three areas: technology attributes, anatomy, and rehabilitation. A total of 272 titles, abstracts, and keywords were initially retrieved, and data were extracted out of 13 articles. Six articles investigated the effects of wearing a soft robotic glove and eight studied the effect or effectiveness of an intervention with it. Some statistically significant and meaningful beneficial effects were confirmed with the 29 outcome measures used. Finally, 11 articles also confirmed users’ satisfaction with regard to the soft robotic glove, while some articles also noticed an increased engagement in the rehabilitation program with this technology. Despite the heterogeneity across studies, soft robotic gloves stand out as a safe and promising technology to improve hand- and finger-related dexterity and functional performance. However, strengthened evidence of the effects or effectiveness of such devices is needed before their transition from laboratory to clinical practice.

Study design Prospective case series. Objectives To assess the effectiveness and safety of two vitamin D3 repletion protocols given to individuals with spinal cord injury (SCI). Setting Publicly-funded intensive inpatient rehabilitation center, Montreal, Canada. Methods Thirty adults with recent SCI complete or incomplete sensorimotor impairments were recruited upon admission from designated regional SCI trauma centers. Participants with serum 25OHD ≤ 30 nmol/L were given 10,000 IU of weekly and 1000 IU of daily vitamin D3 for 36.8 ± 11.9 days (higher dose: HD). Subjects with serum 25OHD > 30 nmol/L received 1000 IU of daily vitamin D3 for 38.2 ± 11.6 days (lower dose: LD). Outcomes were changes in 25OHD levels from baseline to the end of the study period and safety outcomes. Thresholds for vitamin D deficiency, insufficiency and sufficiency were: 25OHD levels ≤30 nmol/L, 30-74 nmol/L, and ≥75 nmol/L. Results At baseline, 34 and 66% of participants had serum 25OHD 30 nmol/L. Both protocols induced a rise in serum 25OHD with a greater increase in the HD vs. LD regimen (31.4 [95% CI: 16.7, 46.0] vs. 11.7 nmol/L [95% CI: 2.2, 21.2]). None of the participants given the HD remained vitamin D deficient, but only one achieved vitamin D sufficiency. Nearly all individuals on the LD regimen remained vitamin D insufficient with only two reaching vitamin D sufficiency. No adverse effects were observed over the course of the supplementation. Conclusions Although 1000 IU of daily vitamin D3 alone or in combination with weekly 10,000 IU for an average of 37.6 days increased serum 25OHD, they were unsuccessful in improving the impaired vitamin D status during inpatient rehabilitation of individuals with a recent SCI.

Study design Case series. Background Changes in the number of muscle synergies (MSs) and in the weighting of muscles composing each MS are typically altered following an incomplete spinal cord injury (iSCI). Wearable robotic exoskeletons (WRE) represent a promising rehabilitation option, though the effects of various WRE control modes on MSs still remain unknown. Objective This case series characterizes how WRE control modes affect the number of MSs and the weighting of muscles composing each MS in individuals with iSCI. Setting Pathokinesioly laboratory of a rehabilitation research center. Methods Three participants with a chronic iSCI walked at a self-selected comfortable speed without and with a WRE set in two trajectory-controlled (Total Assistance, TOT; Assistance-as-Needed, ADAPT) and three non-trajectory controlled modes (High Assistance, HASSIST; High Resistance, HRESIST; NEUTRAL). Surface EMG of eight lower extremity (L/E) muscles was recorded and used to extract MSs using a nonnegative matrix factorization algorithm. Cosine similarity and weighting relative differences characterized similarities in MSs between individuals with iSCI and able-bodied controls. Results The mode providing movement assistance within a self-selected L/E trajectory (HASSIST) best replicated MSs in able-bodied controls during overground walking. MSs extracted with the trajectory-controlled modes differed to the greatest extent from able-bodied group MSs. Conclusions Most WRE control modes did not replicate the motor control required for typical L/E muscle coordination during stereotypical overground walking. These results highlight the need to gain a better understanding of the effects of various control modes on L/E motor control for rehabilitation professionals to incorporate research evidence when selecting WRE control mode(s) during WRE locomotor interventions.

Objectives. To investigate and compare the feasibility, safety, and preliminary effectiveness of home-based self-managed manual wheelchair high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) programs.Methods. Eleven manual wheelchair users were randomly assigned to the HIIT (n=6) or the MICT group (n=5). Both six-week programs consisted of three 40-minute propulsion training sessions per week. The HIIT group alternated between 30 s high-intensity intervals and 60 s low-intensity intervals, whereas the MICT group maintained a constant moderate intensity. Cardiorespiratory fitness, upper limb strength, and shoulder pain were measured before and after the programs. Participants completed a questionnaire on the programs that explored general areas of feasibility.Results. The answers to the questionnaire demonstrated that both training programs were feasible in the community. No severe adverse events occurred, although some participants experienced increased shoulder pain during HIIT. Neither program yielded a significant change in cardiorespiratory fitness or upper limb strength. However, both groups reported moderate to significant subjective improvement.Conclusion. Home-based wheelchair HIIT appears feasible and safe although potential development of shoulder pain remains a concern and should be addressed with a future preventive shoulder exercise program. Some recommendations have been proposed for a larger study aiming to strengthen evidence regarding the feasibility, safety, and effectiveness of HIIT.

Wheelchair mobility is a prerequisite to being able to carry out important activities and to participate in social life. Level of satisfaction with the wheelchair and overall quality of life were found to be positively associated. The aim of this study was to determine the level of satisfaction of French manual wheelchair (MW) users and caregivers with MW characteristics. A total of 132 users and 76 caregivers completed a questionnaire about their level of satisfaction with their MW characteristics. Satisfaction scores were independent of age, sex, reason for MW use, and time of use. As a whole, MW users are satisfied. However, a few parameters such as MW weight and difficulties propelling outdoors demonstrate a low level of satisfaction among users. MW weight, brakes, and height of pushing handles are the less satisfying elements among caregivers. In conclusion, the majority of French MW users are satisfied, but some characteristics, such as weight, must be optimized. Considering caregiver needs is paramount when aiming to improve MW parameters such as brakes or pushing handles. Improvement in some wheelchair parameters seems to be important in achieving improved level of satisfaction and increased participation and active lifestyle among MW users and caregivers.

Eighteen manual wheelchair users (MWUs) with spinal cord injury participated in a training session on a new manual wheelchair simulator with haptic biofeedback (HB). The training aimed to modify participants' mechanical effective force (MEF) along the push phase to achieve a target MEF pattern slightly more effective than their pre-training pattern. More HB was provided if the participants' achieved MEF pattern deviated from the target. Otherwise, less HB was provided. The deviation between the participants' achieved MEF and the target, as well as the mean achieved MEF, were computed before, during and after the training session. During the training, participants generally exceeded the target pattern at the beginning of the push cycle and achieved it towards the end. On average, participants also increased their mean MEF by up to 15.7% on the right side and 12.4% on the left side between the pre-training and training periods. Finally, eight participants could modify their MEF pattern towards the target in post-training. The simulator tested in this study represents a valuable tool for developing new wheelchair propulsion training programs. Haptic biofeedback also provides interesting potential for training MWUs to improve propulsion effectiveness.

Background For individuals who sustain a complete motor spinal cord injury (SCI) and rely on a wheelchair as their primary mode of locomotion, overground robotic exoskeletons represent a promising solution to stand and walk again. Although overground robotic exoskeletons have gained tremendous attention over the past decade and are now being transferred from laboratories to clinical settings, their effects remain unclear given the paucity of scientific evidence and the absence of large-scale clinical trials. This study aims to examine the feasibility of a locomotor training program with an overground robotic exoskeleton in terms of recruitment, attendance, and drop-out rates as well as walking performance, learnability, and safety. Methods Individuals with a SCI were invited to participate in a 6 to 8-week locomotor training program with a robotic exoskeleton encompassing 18 sessions. Selected participants underwent a comprehensive screening process and completed two familiarization sessions with the robotic exoskeleton. The outcome measures were the rate of recruitment of potential participants, the rate of attendance at training sessions, the rate of drop-outs, the ability to walk with the exoskeleton, and its progression over the program as well as the adverse events. Results Out of 49 individuals who expressed their interest in participating in the study, only 14 initiated the program (recruitment rate = 28.6%). Of these, 13 individuals completed the program (drop-out rate = 7.1%) and attended 17.6 ± 1.1 sessions (attendance rate = 97.9%). Their greatest standing time, walking time, and number of steps taken during a session were 64.5 ± 10.2 min, 47.2 ± 11.3 min, and 1843 ± 577 steps, respectively. During the training program, these last three parameters increased by 45.3%, 102.1%, and 248.7%, respectively. At the end of the program, when walking with the exoskeleton, most participants required one therapist (85.7%), needed stand-by or contact-guard assistance (57.1%), used forearm crutches (71.4%), and reached a walking speed of 0.25 ± 0.05 m/s. Five participants reported training-related pain or stiffness in the upper extremities during the program. One participant sustained bilateral calcaneal fractures and stopped the program. Conclusions This study confirms that larger clinical trials investigating the effects of a locomotor training program with an overground robotic exoskeleton are feasible and relatively safe in individuals with complete motor SCI. Moreover, to optimize the recruitment rate and safety in future trials, this study now highlights the need of developing pre-training rehabilitation programs to increase passive lower extremity range of motion and standing tolerance. This study also calls for the development of clinical practice guidelines targeting fragility fracture risk assessment linked to the use of overground robotic exoskeletons.

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.

Health professionals are hesitant to recommend psychiatric service dogs (PSD) to veterans with post-traumatic stress disorder given that there is no scientific evidence to support their effectiveness. In recent years, new dog training schools for PSD have emerged in the community with different approaches. The objective of this study is to propose a logic model that examines how service dogs assist veterans with post-traumatic stress disorder and that shows concerns related to PSD. A participatory design through a consultation with stakeholders across Canada was realized (dog trainers=12, veterans having a PSD=2, veterans from advocate organizations=4, medical doctors=3, Canadian general standard board=1). They were interviewed in February 2015 via a phone qualitative interview. Questions were about tasks for which the dog should be trained to help the veteran, disadvantages, difficulties and concerns related to having a PSD, promotion and standardization of PSD, difficulties regarding the evaluation process, dog allocation and follow-up/abandonment of the dog. A qualitative thematic content analysis was achieved with the interview’s materiel. A logic model was created to classify the theory related to diagnosis and treatment for post-traumatic stress disorder as well as the results of the consultation (n=30 themes). These included 4 dog roles (detection and intervention when the veteran is anxious, contributing to a feeling of safety, promoting a sense of relaxation, socialisation), 2 potential major undesirable events with the PSD, 9 potential effects of the PSD, 3 potential organizational impacts of the service dog and 12 co-factors affecting the accessibility and efficacy of the intervention with PSD. Some themes contradict the legal acceptance in the literature. Testimonies about the reported efficacy of PSD are enthusiastic compared to what was found in the literature. Future research is needed to validate how and when PSD’s roles and task make the differences in everyday life of the veterans with PSTD.

Muscle vibrations can induce motor responses and illusions of complex movements. However, inducing gait-like cyclical movements and illusions requires the application of multiple fast alternating vibrations to lower-limb muscles. The objectives were (1) to test the feasibility of delivering complex vibrations in a time-organized manner and (2) to illustrate the possibility of inducing alternate gait-in-place-like movements using these vibrations. Patterns of vibration, produced by 12 vibrators applied bilaterally on the flexor and extensor muscle groups of the lower limbs, were based on normal gait kinemat- ics. We tested 1 s and 2 s cycle patterns of vibration. Vibrator responses were assessed using auto- and crosscorrelations and frequency analyses based on accelerometry measurements, and compared between patterns. High auto- (>0.8) and crosscorre- lation (>0.6) coefficients demonstrated a good response by the vibrators to the control signal. Vibrations induced cyclical, low-amplitude stepping-in-place movements that mimicked alternate walking movements with both legs, with 1 s and 2 s cycle durations, in one nondisabled participant and one partici- pant with American Spinal Injury Association Impairment Scale B spinal cord injury standing, relaxed, with body-weight support. Electromechanical vibrators can deliver complex cyclical vibrations and trigger gait-like lower-limb movements. These results warrant the application of these vibration patterns on individuals with sensorimotor impairments to test their potential in gait rehabilitation.

INTRODUCTION The majority of people who sustain a spinal cord injury (SCI) will not regain the necessary sensorimotor capabilities to walk independently or efficiently and must consequently learn to get around in a manual wheelchair (MWC). During the rehabilitation process, they will be encouraged to learn basic and advanced MWC skills so they can optimize their level of independence during MWC propulsion and MWC-related functional activities performed in their natural environment. For example, they will often have to negotiate slopes of different lengths and angles. For MWC users (MWUs), slopes are not just an environmental or architectural challenge to overcome, but they also represent a way to access many public and private spaces or buildings, which facilitates their social integration and participation [1]. According to various recommendations and standards in Canada and the United States [2-4], access ramps can have different slopes, ranging from 1 unit of height to 12, 16, or 20 units of length for ramps less than 9 m long in new buildings or 8 or 10 units of length for ramps less than 3 m long or for vertical rises less than 15 cm in existing buildings or confined spaces. Under no circumstance are slopes steeper than 1:8 permitted by these recommendations and standards. However, in reality, slopes are sometimes steeper because of space limitations (e.g., private residential property) or the inherent inability to modify the natural environment. Consequently, it is relevant to gain additional insight on the specificities of these different slopes during MWC propulsion. To date, only a few studies have investigated upper-limb (UL) efforts during uphill propulsion among MWUs. In a study done with 20 MWUs with various diagnoses, Sanford et al. reported that, for a 9 m-long adjustable slope, 85 percent of the participants could climb a slope of 1:12, 80 percent successfully negotiated a 1:10 slope, and only 75 percent managed to ascend a 1:8 slope while propelling their own MWC at a self-selected natural speed [5]. Moreover, other studies confirmed that a substantial number of MWUs are unable to climb steeper slopes: Templer et al. reported that only 80 percent of MWUs could manage a slope gradient of 1:10 [6], Sweeney et al. mentioned that 88 percent of their participants were able to climb 1:12 to 1:7 slopes [7], and Steinfield et al. documented that approximately 50 percent of MWUs tested could propel the full length of a 1:12 ramp measuring approximately 40 m in length [8]. To date, no study has investigated whether these success rates measured during uphill propulsion in a simulated natural environment are comparable with those reached during treadmill propulsion among MWUs. In addition to the UL efforts routinely generated by MWUs during propulsion and other functional activities (e.g., transfers, pressure-relief lifts, loading the MWC in a car), propelling uphill puts additional demand on the MWU's ULs, which further increases the risk of second ary musculoskeletal impairments, especially at the wrists and shoulders [9-10]. In fact, Arabi et al. calculated among nondisabled subjects that 46 percent of the maximal isometric propulsive force generated is necessary to move an MWC up a slope of 1:20 and 61 percent for a slope of 1:10 when propelling on a dynamometer [11]. Richter et al. found that among a large group of MWUs with SCI, propelling at a self-selected velocity on a motorized treadmill, the speed was about 1.5 and 2.7 times slower when pushing up 3[degrees] and 6[degrees] slopes, respectively, in comparison with the level surface (0[degrees] slope) [12]. Additionally, Richter et al. also documented that the peak total force ([F.sub.TOT]) was about 1.7 and 2.2 times slower when pushing up 3[degrees] and 6[degrees] slopes, respectively, in comparison with the level surface (0[degrees] slope) despite the reduced treadmill speed [12]. More recently, Yang et al. found that among a group of MWUs with SCI, propelling at a steady speed of 0. …

Introduction/Background Multiple patterned vibration applied on lower limb joints in individuals after incomplete spinal cord injury (iSCI) generates gait-like movements at a cadence specific to the vibration pattern. This intervention is currently tested on individual with iSCI, who may need body weight support. The main objective of the study was to quantify perceptions associated to sensory afferents generated by multiple vibrations by iSCI participants. The second objective was to determine whether weight support and cadence of the simulated gait cycles affects perceptions before and after 15 gait-like vibrations training sessions. Material and method Six participants (21–77 years old) with an incomplete spinal cord injury (ASIA Impairment Scale grade C&D) received gait-like vibrations in a standing position, with different levels of weight relief (0%/20%/40%), and two gait cadences (60 and 120 steps/min). Perception was evaluated in each condition with a Visual Analog Scale (VAS), before and after 15 training sessions over three weeks. Results Every participant showed good perception of a gait motion (VAS score > 5/10) for 1 or more conditions in the pre- and post- training evaluation. Body weight and cycle duration had no effect on perception (less than 1 point difference). Perception increased, though not significantly by 2.2 (1.1) points after training, with the increase particularly marked in conditions with low score pre-training. Conclusion Individuals with iSCI perceived gait motion during the application of patterned gait-like vibrations, which may participate to the effect of gait vibration training individuals with iSCI in intensive rehabilitation, regardless of their need for body weight support.

Background: The population with a spinal cord injury (SCI) largely remains inactive following discharge from rehabilitation despite evidence on the benefits of physical activity. These individuals need to develop skills to self-manage their condition in order to prevent secondary comorbidities and rehospitalization. A Web-based physical activity portal can address this need. Few Web-based interventions incorporate theoretical frameworks, behavior change techniques, and modes of delivery into their design. Objective: This study aimed to identify the preferred features of a Web-based self-management physical activity portal through stakeholder engagement with individuals with a spinal cord injury and health care professionals (HCPs). Methods: An interpretative phenomenology methodology and participatory design, along with an integrated knowledge translation approach, were used to conduct this study. Convenience sampling was used to recruit individuals with an SCI living in the community, who were either interested or already engaging in physical activity, and HCPs working with individuals with an SCI, from three city-based rehabilitation sites. Individual 1-hour sessions involving navigation of an existing website and a semistructured interview were conducted with all participants. Individuals with an SCI completed a demographics questionnaire prior to the individual sessions, while demographic information of the HCPs was collected during their interviews. Additionally, all participants were asked a question on their intention to use or recommend a portal. An in-depth thematic analysis was used to derive themes from participants’ responses. Results: Thirteen individuals with an SCI and nine HCPs participated in the study. Five core themes emerged: (1) knowledge: guidance and barrier management; (2) possibility of achievement: the risks and benefits of physical activity and modelling; (3) self-regulation strategies: action planning, goal setting, tracking, rewards, and reminders; (4) interactivity: peers and professionals; and (5) format: appearance, language, and ease of use. The mean (median) ratings of the likelihood of promoting and using a Web-based portal tailored to individuals’ needs were 9.00 (8.78) and 7.75 (7.88) for HCPs and individuals with an SCI, respectively. Conclusions: This study highlights features of an online self-management platform that can provide individuals with an SCI the motivation and volition to engage in physical activity. These findings will inform the design of a Web-based self-management physical activity portal to increase physical activity adherence and behavior change.

Objective: To compare the mechanical and muscular efforts generated in the non-dominant upper limb (U/L) when ascending a ramp with and without the use of a mobility assistance dog (ADMob) in a manual wheelchair user with a spinal cord injury. Method: The participant ascended a ramp at natural speed using his personal wheelchair with (three trials) and without (three trials) his ADMob. Movement parameters of the wheelchair, head, trunk, and non-dominant U/L (i.e. hand, forearm, and arm segments) were recorded with a motion analysis system. The orthogonal force components applied on the hand rims by the U/Ls were computed with instrumented wheels. Muscular activity data of the clavicular fibers of the pectoralis major, the anterior fibers of the deltoid, the long head of the biceps brachii, and the long head of the triceps brachii were collected at the non-dominant U/L. Results: During uphill propulsion with the ADMob, the total and tangential forces applied at the non-dominant handrim, along with the rate of rise of force, were reduced while mechanical efficiency was improved compared to uphill propulsion without the ADMob. Similarly, the resultant net joint movements (wrist, elbow, and shoulder) and the relative muscular demands (biceps, triceps, anterior deltoid, pectoralis major) decreased during uphill propulsion with an ADMob versus without an ADMob. Conclusion: Propelling uphill with the assistance of an ADMob reduces U/L efforts and improves efficiency compared to propelling uphill without its assistance in a manual wheelchair user with a spinal cord injury.

The purpose of this single-subject case study was to quantify the effect of gait-like vibration training on gait abilities after an incomplete spinal cord injury (SCI). A 62-year-old male with a chronic American Spinal Injury Association Impairment Scale D SCI at T11 completed nine sessions of gait-like vibration training in a standing position. Self-selected gait speed and distance covered within 6 min were determined before and after training to evaluate the impact of training on gait performance. Associated changes in gait kinematics were assessed with a three-dimensional motion analysis system. Results showed an improvement of gait speed (0.26 vs 0.35 m s−1) and distance (23 vs 37 m) after nine gait-like vibration training sessions (+34.6%; +60.9%). In addition, more bilateral hip extension and larger left hip range of motion improved hip–knee cyclograms. Gait-like vibration training improved gait abilities in a person with chronic incomplete SCI.

Background Quantifying the integrity of the Achilles tendon (AT) is a rehabilitation challenge. Adopting quantitative ultrasound measurements (QUS measurements) of the AT could fill this gap by 1) evaluating the test-retest reliability and accuracy of QUS measurements of the AT; 2) determining the best protocol for collecting QUS measurements in clinical practice. Methods A total of 23 ATs with symptoms of Achilles tendinopathy and 63 asymptomatic ATs were evaluated. Eight images were recorded for each AT (2 visits × 2 evaluators × 2 images). Multiple sets of QUS measurements were taken: geometric (thickness, width, area), first-order statistics (computed from a grayscale histogram distribution: echogenicity, variance, skewness, kurtosis, entropy) and texture features (computed from co-occurrence matrices: contrast, energy, homogeneity). A generalizability study quantified the reliability and standard error of measurement (accuracy) of each QUS measurement, and a decision study identified the best measurement taking protocols. Results Geometric QUS measurements demonstrated excellent accuracy and reliability. QUS measurements computed from the grayscale histogram distribution revealed poor accuracy and reliability. QUS measurements derived from co-occurrence matrices showed variable accuracy and moderate to excellent reliability. In clinical practice, using an average of the results of three images collected by a single evaluator during a single visit is recommended. Conclusions The use of geometric QUS measurements enables quantification of AT integrity in clinical practice and research settings. More studies on QUS measurements derived from co-occurrence matrices are warranted.

Objectives.To quantify the association between performance-based manual wheelchair propulsion tests (20 m propulsion test, slalom test, and 6 min propulsion test), trunk and upper extremity (U/E) strength, and seated reaching capability and to establish which ones of these variables best predict performance at these tests.Methods.15 individuals with a spinal cord injury (SCI) performed the three wheelchair propulsion tests prior to discharge from inpatient SCI rehabilitation. Trunk and U/E strength and seated reaching capability with unilateral hand support were also measured. Bivariate correlation and multiple linear regression analyses allowed determining the best determinants and predictors, respectively.Results.The performance at the three tests was moderately or strongly correlated with anterior and lateral flexion trunk strength, anterior seated reaching distance, and the shoulder, elbow, and handgrip strength measures. Shoulder adductor strength-weakest side explained 53% of the variance on the 20-meter propulsion test-maximum velocity. Shoulder adductor strength-strongest side and forward seated reaching distance explained 71% of the variance on the slalom test. Handgrip strength explained 52% of the variance on the 6-minute propulsion test.Conclusion.Performance at the manual wheelchair propulsion tests is explained by a combination of factors that should be considered in rehabilitation.

Introduction/Background Power wheelchair (PW) skills training is generally seen as insufficient by both clinicians and PW users. A virtual reality (VR) simulator may be helpful in improving PW driving skills, when used in addition to regular training. In previous work, challenging PW driving activities have been identified through interviews with expert clinicians and PW users and were then integrated in the McGill Immersive Wheelchair simulator (miWe). Our objective was to evaluate the effectiveness of VR simulator training on real PW driving skills. Material and method The miWe simulator included six PW driving activities (bathroom, shopping center, supermarket, elevator, street crossing and adapted transport vehicle). A computer with a joystick was installed in the participant's home. Participants (new PW users) were randomly allocated to the simulator or control group. Participants in the control group were asked to practice on a racing videogame (also using a joystick). Participants in both groups were asked to practice for at least 20 minutes every two days, over a two-week period. We compared real wheelchair driving skills as measured by the wheelchair skills test (WST), before and after the intervention. Results A total of 43 participants completed the study. All practiced on the simulator or computer game at least twice as much as what was minimally required. Results indicate that the WST scores in the experimental group increased by 7% on average, compared to 2% in the control group. Feedback regarding ease of use and potential usefulness of the PW simulator was very positive. Conclusion Our preliminary results show that miWe simulator training may lead to improved wheelchair skills as compared to training with a racing videogame. A PW simulator may be helpful to new users if it promotes the practice of activities in specific environmental contexts to complement the basic skills training received in the clinic.
