Abstract
Along with the steadily rising elderly population in Japan, the number of aged persons with difficulties in walking is increasing. These patients take a walking training in hospitals imposing a constant and heavy burden upon the health care personnel who assist them. A walking support machine is needed that can provide them with partial body weight support and protect them from falling down in order to decrease caregiver burden and to increase patient's independence. This paper proposes the walking support machine with the safety devices, which provide them with partial body weight support and prevent them from falling. These safety devices consist of passive components without actuators, controllers and batteries. The usefulness of these devices is experimentally examined.
