Design objective
Researchers developed a dual-power, lever-propelled wheelchair intended to improve propulsion efficiency, ergonomics, and user effort. The prototype was designed for people with lower-limb disabilities, with particular attention to affordability and usability in low-income settings. Its design incorporated features from tricycle and lever-propelled wheelchairs and followed WHO wheelchair standards. A computer-aided design model also considered low-cost manufacturing requirements before the prototype was fabricated.
Evaluation approach
The study began with a descriptive review of relevant wheelchair literature and patents. Twenty-five unimpaired participants tested the prototype after a brief familiarisation and training session. They completed repeated propulsion trials on a predefined outdoor course that included straight movement, turning, and braking. Researchers collected feedback about ease of use, comfort, safety, and propulsion effectiveness using the Quebec User Evaluation of Satisfaction with Assistive Technology, or QUEST 2.0.
Reported findings
The source reports positive feedback from participant trials concerning the propulsion mechanism, stability, and overall build quality. Feedback also indicated that the dual-power stroke mechanism reduced user effort during propulsion. However, the evaluation involved unimpaired participants and is described as preliminary. The source is an abstract summary rather than a full-paper review, so these findings do not establish treatment recommendations or broader clinical effectiveness.
