Supporting Sit-To-Stand Rehabilitation Using Smartphone Sensors to provide tactile feedback

For many stroke survivors standing up from sitting is problematic. Recovering this important movement depends on practice. This can be carried out at home, however, it is difficult to get feedback on movement performance outside of therapy sessions. We aim to support stroke survivors through the rehabilitation process by developing and evaluating a low-cost system using smartphones linked wirelessly to small feedback units on the leg that vibrate according to performance. We have developed a prototype that shows great promise but is too bulky for clinical use. In this project we aim to develop a miniaturised version and conduct evaluations.

Feedback on movement performance to correct deviations and provide motivation is the cornerstone of movement rehabilitation, along with task repetition. However, this kind of information is typically only available during sessions with rehabilitation professionals, unnecessarily limiting rehabilitation potential. The aim of this startup project, funded by Chest, Heart and Stroke Scotland between Mark Dunlop and Andy Kerr , is to create a system to assist sit-to-stand (STS) rehabilitation through the use of haptic feedback on balance to support rehabilitation in the home using readily available technology (smartphone) and custom made leg-mounted tactile feedback modules.
