The technique for quantifying stretch reflex allowing multi degree of freedom movement was developed. Measurements are made from a triaxial accelerometer and an instrumented hammer with force sensor system. Stretch reflex dynamics were estimated using the recorded tapping force and the lower leg velocity. The input-output properties of system relating the reflex velocity were characterized using several measures : time delay (Td), reflex acceleration time (Ta), peak leg velocity (Vp), peak tapping force (Fp), peak reflex velocity-peak tapping force ratio (Vp/Fp). These parameters showed repeatability and to help characterize neuromuscular dynamics of stretch reflex. This technique may be also utilized as an educational tool in the medical field.
