Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline in average daily movement activity at 5 months

    Average daily movement activity is defined as the frequency of in-seat movement will be calculated as total number of weight shifts and pressure reliefs per unit time of wheelchair use (movements/hour).

    baseline (2 weeks) and 5 months

Study Arms (2)

WiSAT Passive

OTHER

This arm is composed of participants who meet their activity threshold over the 4-week period.

Other: WiSAT System, Passive Feedback

WiSAT Active

OTHER

This arm is composed of participants who do not meet their activity threshold over the 4-week period.

Other: WiSAT System, Active Feedback

Interventions

The WiSAT system is installed in the participant's wheelchair cushion and a smartphone application is installed on his/her cellphone. Participants are able to view the application as they please and they will receive no notifications from the app regarding their movement goals.
