Tilt Tracker: Technical Note on an mHealth System to Monitor and Prevent Ulcer Development Among Power Wheelchair Users

Approximately 85% of individuals with spinal cord injuries will develop a pressure ulcer, making these wounds one of the most common and preventable comorbidities associated with this condition. Pressure ulcers can be life threatening due to increased risk of infection, and hospitalization is often required for complex cases. Accordingly, there is a call in the spinal cord injury literature to develop innovative technology for the prevention of pressure ulcers. In response, an interdisciplinary team developed the Tilt Tracker, a dynamic mobile health system that objectively measures pressure redistribution practices in real time and is synchronized to a digital communication platform. This technical note will describe the concept and design of this innovative technology.
