Abstract

Many elderly people suffer from declined motor ability, and it is important to develop an assistive device to support their daily life. Some assistive device have been developed previously to help human sit-to-stand motion, but they generally help body extension slowly and thus the user of the device could not utilize their own muscles. Here, we develop a chair type assist device which lift up the seat to push the hip joint for supporting hip rising and body extension. Our developed device employed a zip chain actuator which realizes fast and strong support to follow the user's movement and provide assistance. Evaluation experiment was performed to assess the effect of developed device on muscle activation of lower limbs during sit-to-stand motion. Results show that the muscle activation of knee extensor decreased significantly compared to that without device support. However, the activation level of flexor is found to be increased to deaccelerate the body extension.
