Abstract: A kinesthetic diagnostic and rehabilitation device enables the user to measure the extent of kinesthetic impairment resulting from a bodily injury, particularly an injury to the lower limbs, and also enables the user to rehabilitate the injury. The device is provided with a rigid platform resting atop an unstable support. The ability of the patient to maintain a fixed position on the platform as a function of the instability of the support enables quantification of the patient's kinesthetic impairment. The device further provides rehabilitative exercise.
