To evaluate the impact of acquiring a power-assist device on participation.
Prospective multicenter cohort study.
Three physical medicine and rehabilitation outpatient centers.
Eighteen individuals with neurological impairments who primarily use manual wheelchairs for mobility.
Participants were followed throughout the process of acquiring a power-assisted mobility device, with assessments conducted at delivery, 3 months, and 6 months post-acquisition.
Participation (Wheelchair Outcome Measure), shoulder pain (Wheelchair User's Shoulder Pain Index), wheelchair skills (Wheelchair Skills Test Questionnaire), and satisfaction with the device (Quebec User Evaluation of Satisfaction with Assistive Technology). Evaluations were performed at baseline (pre-acquisition), delivery, and at 3 and 6 months.
Thirty-six participants were enrolled. Eighteen did not complete the study mostly due to funding difficulties and 18 completed the acquisition. Participation significantly increased, with WHOM scores rising from 19.33 ± 15.02 at baseline to 36.55 ± 17.06 at 3 months (
The acquisition of a power-assist device may enhance participation, wheelchair skills, and reduce mobility-related shoulder pain in manual wheelchair users. Further comparative studies are needed to confirm these findings.
