In-wheel Suspension Study for Manual Wheelchair Users
STUDY BASICS
Do you have a spinal cord injury which occurred at least one year ago and use a manual wheelchair full time (30+ hours per week)? You may be able to participate in a study to examine how in-wheel suspension in manual wheelchairs changes vibrational exposure and how this impacts pain and fatigue. This study involves 2 in-person visits and 12-weeks of in-wheel suspension use. Compensation provided.
STUDY PURPOSE
The purpose of this study is to examine how in-wheel suspension in manual wheelchairs changes vibrational exposure and how this impacts pain and fatigue.
COULD THIS STUDY BE RIGHT FOR YOU?
- You have a spinal cord injury which occurred at least one year ago
- You use a manual wheelchair full time (more than 30 hours per week)
- You use a manual wheelchair with 24” or 25” quick-release wheels
- Your Wheelchair does not have in-frame suspension elements
- You weigh under 265 pounds (weight limit of suspension wheels)
- You have moderate chronic neck and/or back pain
WHAT PARTICIPANTS CAN EXPECT
- 2 visits
- 12-weeks of at-home in-wheel suspension use
IRB: STUDY20020199
- Effects of in-wheel suspension in reducing vibration, neck and back painMEET THE RESEARCHER
