Wheelchair users are at a higher risk for developing pressure injuries due to reduced mobility, impaired sensation, and spending a large portion of their time in the seated position. Pressure injuries can be a very costly and life threatening complication for wheelchair users. One strategy for pressure injury prevention is to complete weight shifts and pressure reliefs. Literature shows that there is a low adherence to the pressure relief and weight shift clinical guidelines by wheelchair users. The Wheelchair in-Seat Activity Tracker (WiSAT) has been developed to help wheelchair users track their in-seat movement and help aid in the prevention of developing pressure injuries. The objective of this preliminary study is to examine the WiSAT system’s potential to impact behavior using a single-subject design and evaluate the clinical protocol developed to assess the effect of the WiSAT system on in-seat movement behavior.
One individual who used a manual wheelchair participated in the study. He completed two study visits and used the WiSAT system in his natural environment for 5 months. The results of his participation revealed that the WiSAT system may have an impact on in-seat behavior, but more subjects are needed to establish the WiSAT system’s effectiveness. In addition, throughout the recruitment process and the participant’s equipment trial, numerous protocol issues were discovered and resolved. The modifications and improvements made as a result of this preliminary study will reduce the extent of future problems with the WiSAT equipment as well as minimize the amount of missing data.
