Study designProspective cohort study.ObjectivesTo evaluate the effects of wheelchair skills training (WSTR) for participants with spinal cord injury (SCI) during peer-led Active Rehabilitation Camps (ARC) in Poland. We hypothesized that participation in ARC will improve wheelchair skill performance and self-efficacy in individuals with SCI. We also aimed to determine demographic and injury-related factors associated with greater improvements in wheelchair skill performance and self-efficacy.SettingThirteen consecutive ARCs in Poland.MethodsParticipants (n = 122) with traumatic or nontraumatic SCI older than 16 years were evaluated at the beginning (T1) and completion (T2) of ARC and at 3-month follow-up (T3) through the Queensland Evaluation of Wheelchair Skills (QEWS) and the Wheelchair Skills Test Questionnaire (WST-Q).ResultsAt T2, 43% of participants reached the threshold for substantial clinically meaningful change in QEWS, 73% in WST-Q capacity, and 67% in confidence, with approximately half of those reporting such gains at T3. At a group level, participants achieved small effect-size improvements (QEWS) at T2; large effects in wheelchair skills capacity at T2 and T3; large effects in wheelchair skill confidence at T2, and low effects at T3. Prior attendance to ARC was the only independent variable that explained 10% of variance in wheelchair capacity gains.ConclusionsPeer-led WSTR during ARCs is highly effective at improving wheelchair skills in individuals with SCI. These improvements are largely retained after three months. Persons with SCI should have a chance to participate in more than one camp to maintain and further improve their wheelchair skills.
