The spasticity measurement system for the quantitative modified Tardieu approach. a Mechanical parts of the sensing device. The upper and lower parts were connected via four sliding tracks to decrease the friction during compression. b A gyroscope was used to record angular velocity and was applied during ankle displacement to identify the angular displacement. A miniature load cell (load button) was used to record resistance during stretch. c The hand-held sensing device recorded and sent signals (angular velocity and resistance) to a computer via an A/D converter during ankle stretch
