A smartphone application that informs weight shifting behavior to promote tissue health

Abstract

One of the most persistent problems affecting wheelchair users is pressure ulcers. These are ulcers that wheelchair users develop in areas of constant pressure or interruption of blood flow to a localized area. Approximately one- third of patients who suffer from spinal cord injuries develop pressure ulcers, and it is a very expensive consequence for these people. Pressure relief exercises can help, but a high percentage of wheelchair users do not perform them enough. Activity trackers today have the ability to sync with smartphone applications to monitor physical activity. The following study uses weight shifting behavior to help wheelchair users. By studying principles of usability engineering and user interface design, the researcher will design a smartphone application that pairs with a weight shift monitoring system to help promote tissue health. The application will illustrate information for the user to make them aware of their behavior and engage them in pressure relief exercises.
