Description of a system developed for a physical therapy clinic to measure hip, knee, and ankle joint angles during walking as part of the gait assessment of its post stroke patients. Designed by engineering students at the Rochester Institute of Technology in upstate New York, the Motion Tracking System is based on data collected through 8 gyroscopes enclosed in small plastic cases and attached to the patients’ skin using EGC electrodes. Angular velocity data are sent from each gyroscope to a microcontroller and then transmitted via Bluetooth to a computer where they are processed, displayed, and saved using a Java script written by the design team. The raw angular velocity data are integrated to obtain angular displacement. These data are then stored for comparison in future therapy sessions. The system may be the basis for future telemedicine work the clinic is considering. Total project cost was about 1,450 dollars.
