Evaluation of a wheelchair prototype with non-conventional, manual propulsion

Abstract

Objective To evaluate the results of a user satisfaction questionnaire on a new type of lever-propelled wheelchair designed to avoid the discomfort and potential repetitive strain injuries related to conventional hand-rim propulsion. Methods Seventeen participants filled out a questionnaire to rate their conventional wheelchair and the prototype (after 2 days use) in terms of comfort, adjustability, steering/ride, manoeuvrability, stability when crossing obstacles, safety, weight, size, portability and appearance. Overall satisfaction was also scored. Results According to the user questionnaire results, the lever-propelled prototype chair was rated as significantly superior than conventional wheelchairs in terms of comfort, safety and overall satisfaction. The prototype was rated significantly inferior in terms of size, adaptability, appearance and crossing obstacles. Conclusion We conclude that the prototype wheelchair is highly acceptable and comfortable and can be recommended to disabled sportspersons. The prototype's weak points are mainly related to ergonomic aspects, which could be improved in future models.
