Objective: To determine the relationship between mobility performance measures and Wheelchair Skill Test (WST) scores and to establish the test-retest and inter-rater reliability of these measures. Methods: Forty patients with spinal cord injury participated in this study. Subjects performed the Wheelchair Skill Test and mobility performance tests: maximal velocity (V max), spontaneous velocity (V spont) and a 10-m back and forth slalom (S time). Eighteen patients with spinal cord injury participated in a second testing session to evaluate test-retest reliability and, among these patients, 8 participated in a third testing session to evaluate inter-rater reliability. Results: Spearman's correlation coefficients calculated between WST and V max, V spont and S time were high and significant (p < 0.05). The intraclass correlation coefficients (ICC (2.1)) evaluating test-retest reliability for V max, V spont and S time were 0.94, 0.84 and 0.88, respectively. The ICC evaluating inter-rater reliability for V max, V spont and S time were 0.92, 0.92 and 0.95, respectively. Reliability results were confirmed by Bland-Altman plots. Conclusion: V max and S time could be used to evaluate wheelchair skills and to create a new scale, whereas V spont is the least appropriate of these measurements to describe wheelchair skills. © 2012 The Authors.

Purpose: The purpose of this study was to determine whether self-efficacy can account for the relationship between wheelchair skills and leisure-time physical activity (LTPA) in people with spinal cord injury (SCI). Method: Fifty-four manual wheelchair users with SCI participated in this cross-sectional study. Participants completed a wheelchair skills test, and self-report measures of wheelchair-use self-efficacy, LTPA barrier self-efficacy, and LTPA. It was hypothesized that a positive wheelchair skills-LTPA relationship would be mediated by wheelchair-use self-efficacy and LTPA barrier self-efficacy. Results: Using linear regression models, a positive association between wheelchair skills and LTPA was established (β=0.27, p < 0.05). LTPA barrier self-efficacy was a significant partial mediator, explaining 47.7% of the variance of the total relationship between skills and LTPA. Wheelchair-use self-efficacy was not a significant mediator of the wheelchair skills-LTPA relationship. Conclusions: Wheelchair skills play a modest role in LTPA participation and may facilitate LTPA, if skills help people feel more self-efficacious in their abilities to overcome LTPA barriers. The results have implications for understanding and improving LTPA participation. Improvements in wheelchair skills may facilitate LTPA, if people are taught the skills needed to increase their self-efficacy to overcome barriers to LTPA participation. Implications for Rehabilitation Many Canadians with spinal cord injury (SCI) do not participate in leisure-time physical activities (LTPAs). Lack of LTPA participation is associated with increased health risks in people with SCI, who are already at higher risk for health problems when compared to the able-bodied population. The belief in one's ability to overcome barriers (barrier self-efficacy) to LTPA plays a significant role in LTPA participation for people with SCI. People with SCI may benefit from a formal wheelchair skills training program to improve their barrier self-efficacy which can lead to more participation in LTPA and decreased health risks.

Disability and Rehabilitation: Assistive Technology | Year: 2015

Purpose: To explore power wheelchair users', caregivers' and clinicians' perspectives regarding the potential impact of intelligent power wheelchair use on social participation. Methods: Semi-structured interviews were conducted with power wheelchair users (n=12), caregivers (n=4) and clinicians (n=12). An illustrative video was used to facilitate discussion. The transcribed interviews were analyzed using thematic analysis. Results: Three main themes were identified based on the experiences of the power wheelchair users, caregivers and clinicians: (1) increased social participation opportunities, (2) changing how social participation is experienced and (3) decreased risk of accidents during social participation. Conclusion: Findings from this study suggest that an intelligent power wheelchair would enhance social participation in a variety of important ways, thereby providing support for continued design and development of this assistive technology.Implications for RehabilitationAn intelligent power wheelchair has the potential to:Increase social participation opportunities by overcoming challenges associated with navigating through crowds and small spaces.Change how social participation is experienced through "normalizing" social interactions and decreasing the effort required to drive a power wheelchair.Decrease the risk of accidents during social participation by reducing the need for dangerous compensatory strategies and minimizing the impact of the physical environment. © 2014 Informa UK Ltd.

Objective: To determine the reliability of quantitative measures of the long head of the biceps tendon using an ultrasound-imaging system. Design: Intra- and inter-rater reliability study. Subjects/patients: Thirty-one participants without shoulder pain. Methods: All participants took part in 3 ultrasound imaging sessions; they were assessed by 2 evaluators (inter-rater reliability), one of whom assessed them twice (intra-rater reliability). All measurements were taken at the widest identified part of the tendon using longitudinal and transverse views. Measurements of the long head of the biceps tendon included width, thickness and cross-sectional area. Intraclass correlation coefficients and minimal detectable change were used to characterize reliability. Results: Intra- and inter-rater reliabilities were excellent for all measures when the mean of 2 measures were considered, except for inter-rater reliability of the width, for which it ranged from 0.76 to 0.86. Minimal detectable change ranged from 0.3 to 1.6 mm for width and thickness, and from 2.8 to 4.9 mm2 for cross-sectional area. Conclusion: Ultrasound measurement of the long head of the biceps tendon is a highly reliable method, except for the width. When measuring the long head of the biceps tendon, a mean of 2 measurements is recommended. Now that reliability has been shown in healthy individuals, the next step will be to determine the validity/reliability of these quantitative measures in symptomatic shoulders. © 2016 The Authors.

Introduction: Over the last decades, psychosocial factors were identified by many studies as significant predictive variables in the development of disability related to common low back disorders, which thus contributed to the development of biopsychosocial prevention interventions. Biopsychosocial interventions were supposed to be more effective than usual interventions in improving different outcomes. Unfortunately, most of these interventions show inconclusive results. The use of screening questionnaires was proposed as a solution to improve their efficacy. The aim of this study was to validate a new screening questionnaire to identify workers at risk of being absent from work for more than 182 cumulative days and who are more susceptible to benefit from prevention interventions. Methods: Injured workers receiving income replacement benefits from the Quebec Compensation Board (n = 535) completed a 67-item questionnaire in the sub-acute stage of pain and provided information about work-related events 6 and 12 months later. Reliability and validity of the 67-item questionnaire were determined respectively by test-retest reliability and internal consistency analysis, as well as by construct validity analyses. The Cox regression model and the maximum likelihood method were used to fix a model allowing calculation of a probability of absence of more than 182 days. Criterion validity and discriminative capacity of this model were calculated. Results: Subsections from the 67-item questionnaire were moderately to highly correlated 2 weeks later (r = 0.52-0.80) and showed moderate to good internal consistency (0.70-0.94). Among the 67-item questionnaire, six sub-sections and variables (22 items) were predictive of long-term absence from work: fear-avoidance beliefs related to work, return to work expectations, annual family income before-taxes, last level of education attained, work schedule and work concerns. The area under the ROC curve was 73%. Conclusions: The significant predictive variables of long-term absence from work were dominated by workplace conditions and individual perceptions about work. In association with individual psychosocial variables, these variables could contribute to identify potentially useful prevention interventions and to reduce the significant costs associated with LBP long-term absenteeism. © Springer Science+Business Media, LLC 2011.
