Evaluation of Wheelchair In-Seat Activity Tracker

Summary

Individuals who use wheelchairs are at an increased risk of developing pressure injuries on the parts of the body that are in constant contact with the wheelchair. The development of pressure injuries can cause reduced mobility, reduced activity and participation, greater unemployment, increased risk for future pressure injury development, and premature death. There are numerous risk factors associated with developing pressure injuries. Individuals can reduce the risk of pressure injury formation by changing positions, weight-shifting, and using special cushions, but many people still struggle with pressure injuries.

This study is designed to assess the clinical effectiveness of WiSAT (Wheelchair in-Seat Activity Tracker). WiSAT is a tool designed to help prevent the development of pressure ulcers by changing behaviors that can lead to pressure ulcers. WiSAT monitors and provides real-time feedback on weight shifts and pressure relief behaviors while sitting in a wheelchair.
