Abstract
The authors applied pneumatic actuators to the rehabilitation support of knee and ankle joint motion. Considering the characteristics of the actuator, the authors combined plural actuators as an antagonistic way. First, several layout of the actuators are examined for the knee joint motion and the motion is compared depending on the layout of the actuators. Next, the four actuators are combined for the two DoF motion of the ankle joint, and the motion is compared with and without load. Then, the authors have discussed the availability of the pneumatic actuator to the rehabilitation support, and have confirmed that the actuation is applicable to the coercive joint motion for expanding the joint angle range and the resistive motion for the training of muscles.
