Brief Summary

The purpose of this three phase study is to evaluate a Pushrim Activated Power Assist Wheelchair (PAPAW). Phase I will examine whether the steady-state, metabolic energy efficiency for propelling a manual wheelchair with and without the device will be significantly different. In Phase II, wheelchair users will evaluate the PAPAW over activities of daily living course to determine its usability and acceptability and to identify areas for future development. Finally, in phase III, comparison of activities of daily living in the community will be made between the subjects when using their personal wheelchair and a PAPAW.

Pushrim Activated Power Assist Wheelchair

EXPERIMENTAL

Participants will be asked to propel both their own chair and a pushrim activated power assist wheelchair on a computer controlled wheelchair dynamometer.

Device: Pushrim Activated Power Assist

Interventions

Pushrim Activated Power Assist DEVICE

The PAPAW is an electrically-powered add-on unit for common manual wheelchairs. The unit automatically supplements the users manual pushrim input with additional rear-wheel torque for up to six kilometers/hour traveling velocity. The amount of added torque is provided proportional to the user input to the pushrims. Movement and braking assistance is provided for both forward and rearward travel. Several types and sizes are available based on users operating strength, needs and anthropometry. The PAPAWs to be tested during this study will be the JWII (Yamaha Motor Corporation).
