Title: A Smartphone Application That Informs Weight Shifting Behavior to Promote Tissue Health

Abstract:      One of the most persistent problems affecting wheelchair users is decubitus ulcers, otherwise known as pressure sores or 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 a pressure ulcer and it is a very expensive consequence for these people. Looking at current technology, smartphone applications have become a popular method to monitor physical activity. Activity trackers such as the Fitbit can monitor running or sleep; this 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.
