ABSTRACT
OBJECTIVE: To test the hypothesis that caregivers enhance the wheelchair skills capacity and confidence of the power wheelchair users to whom they provide assistance, and to describe the nature of that assistance. DESIGN: Multicenter cross-sectional study. SETTING: Rehabilitation centers and communities. PARTICIPANTS: Participants (N=152) included caregivers (n=76) and wheelchair users (n=76). INTERVENTIONS: None. MAIN OUTCOME MEASURES: Version 4.3 of the Wheelchair Skills Test (WST) and the Wheelchair Skills Test-Questionnaire (WST-Q). For each of the 30 individual skills, we recorded data about the wheelchair user alone and in combination (blended) with the caregiver. RESULTS: The mean total WST capacity scores ± SD for the wheelchair users alone and blended were 78.1%±9.3% and 92.4%±6.1%, respectively, with a mean difference of 14.3%±8.7% (P<.0001). The mean WST-Q capacity scores ± SD were 77.0%±10.6% and 93.2%±6.4%, respectively, with a mean difference of 16.3%±9.8% (P<.0001). The mean WST-Q confidence scores ± SD were 75.5%±12.7% and 92.8%±6.8%, respectively, with a mean difference of 17.5%±11.7% (P<.0001). The mean differences corresponded to relative improvements of 18.3%, 21.0%, and 22.9%, respectively. The nature and benefits of the caregivers' assistance could be summarized in 7 themes (eg, caregiver provides verbal support [cueing, coaching, reporting about the environment]). CONCLUSIONS: Caregivers significantly enhance the wheelchair skills capacity and confidence of the power wheelchair users to whom they provide assistance, and they do so in a variety of ways. These findings have significance for wheelchair skills assessment and training.

OBJECTIVES: To test the hypothesis that powered wheelchair users who receive the Wheelchair Skills Training Program (WSTP) improve their wheelchair skills in comparison with a control group that receives standard care, and secondarily to assess goal achievement, satisfaction with training, retention, injury rate, confidence with wheelchair use, and participation. DESIGN: Randomized controlled trial. SETTING: Rehabilitation centers and communities. PARTICIPANTS: Powered wheelchair users (N=116). INTERVENTION: Five 30-minute WSTP training sessions. MAIN OUTCOME MEASURES: Assessments were done at baseline (t1), posttraining (t2), and 3 months posttraining (t3) using the Wheelchair Skills Test Questionnaire (WST-Q version 4.1), Goal Attainment Score (GAS), Satisfaction Questionnaire, injury rate, Wheelchair Use Confidence Scale for Power Wheelchair Users (WheelCon), and Life Space Assessment (LSA). RESULTS: There was no significant t2-t1 difference between the groups for WST-Q capacity scores (P=.600), but the difference for WST-Q performance scores was significant (P=.016) with a relative (t2/t1 × 100%) improvement of the median score for the intervention group of 10.8%. The mean GAS ± SD for the intervention group after training was 92.8%±11.4%, and satisfaction with training was high. The WST-Q gain was not retained at t3. There was no clinically significant difference between the groups in injury rate and no statistically significant differences in WheelCon or LSA scores at t3. CONCLUSIONS: Powered wheelchair users who receive formal wheelchair skills training demonstrate modest, transient posttraining improvements in their WST-Q performance scores, have substantial improvements on individualized goals, and are positive about training.
