About this study
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.

Objectives:
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.
Research Design:
This is a repeated measures design type study, conducted in different locations for each phase: a biomechanics laboratory, an ADL driving course, and the participants' home environment. Analyzed variables include: metabolic energy expenditures, stroke frequency, upper extremity joint range of motion, participant responses to a visual analog survey, average speed, and actual daily driving time spent in either wheelchair, and daily distance traveled. Subjects will act as their own controls.
Methodology:
Full-time wheelchair users with tetraplegia between the ages of 18 and 65 will be recruited for the study. They will be free of pressure sores, free from any shoulder pain that would prevent them from propelling a manual wheelchair, and have no history of cardiopulmonary disease. A maximum of 50 subjects (fifteen for Phase I and II, and 15 or Phase III, and five for subject drop-out) will be recruited. In Phase I, participants will be asked to propel a PAPAW and their own wheelchair, attached to a wheelchair roller system through three resistance conditions. In Phase II, participants will be asked to propel both wheelchairs over activities of daily living. Finally, Phase III consists of a four-week trial including a two-week test with subjects' own wheelchairs (i.e. own chair trial) and a two-week test where they were provided with the PAPAW (i.e. PAPAW trial). The order of the own chair trial and the PAPAW trial will be randomized.
Clinical Relationship:
For individuals with tetraplegia, PAPAWs reduce energy demands, stroke frequency, and overall joint range of motion when compared to traditional manual wheelchair propulsion. In addition, PAPAWs have the potential to improve the functional capabilities during certain activities of daily living as well as community participation of individuals with tetraplegia. Use of this device could help maintain overall physical capacity while reducing the risk for pain and injuries to the upper extremities.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Pushrim Activated Power AssistDevice
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).
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: Device: Pushrim Activated Power Assist |
What is being measured
The primary outcome is the main question the study is designed to answer.
Oxygen Consumption
Measured: in-lab visit when propelling on a computer controlled wheelchair dynamometer
