This paper described that the ankle joint measurement and control device which has six degrees of freedom by a parallel link mechanism with six actuators. The composite motion of the ankle joint was reproduced in the developped device, and the effect of the combined motion on the lower leg muscle was measured by moving the ankle joint along the reproduced trajectory. The myoelectricity of Tibialis Anterior (TA), Soleus (SOL), Medial Gastrocnemius (MG) and Lateral Gastrocnemius (LG) of the motion combined inversion and plantar flexion was close to that of plantar flexion. The myoelectricity of Peroneus Longus (PL) was close to that of inversion. The results suggested the possibility of local rehabilitation of the lower leg muscle by the device.
