Design and implementation of patient specific virtual reality systems for motor rehabilitation

There is a need for low-cost, in-home rehabilitation systems with increasing numbers of strokes per year. Therefore a virtual reality system for home use in rehabilitation of the hand and wrist that included hardware, middleware, and software was created and tested with healthy sub-jects. The Angle Tracking and Location At-home System (ATLAS) was created with potentiome-ter bend sensors to track finger angle and inertial measurement units (IMUs) to track hand ori-entation and position. To facilitate the communication between the ATLAS and a computer the Device Agnostic Virtual Environment (DAVE) was created as the middleware solution. Patient specific virtual environments have been created for the ATLAS with the goal of increasing sub-ject motivation and outcomes. The ATLAS was found to fit the requirements for a low-cost, in home system for motor rehabilitation.
