大多数老年人抱怨运动的不适，如坐到站（STS）的运动，由于失去他们的下肢肌肉力量随着年龄的增长。本文提出了一种新的被动坐立行走（STSW）辅助设备，以帮助老年人的室内日常生活的物理支持。STSW辅助装置由气缸和气弹簧驱动。站立运动由致动器的延伸驱动，并且坐着运动由重新加载致动器的用户重量的重力自然地驱动。通过测量受试者在STS运动过程中的肌电信号，评价了使用该装置的物理支持效果。结果，在STSW装置的辅助下，平均最大自主等长收缩减少率约为51.2%。这意味着使用辅助设备的用户可以在自然站立的情况下仅使用大约一半的肌肉激活来站立。
Most elderly people complain about the discomfort of movements such as a sit-to-stand (STS) motion through losing their muscular strength of lower extremity over aging. This paper presents a novel passive sit-to-stand and walking (STSW) assistance device to aid in physical support for indoor daily life of the elderly. The STSW assistance device is actuated by a pneumatic cylinder and a gas spring. The standing motion is driven by extension of actuators and the sitting motion is driven naturally with gravitational force of user's weight that reloads actuators. The effect of physical support by using this device was evaluated by experiment with measuring electromyograph signals of subjects during STS motion. As a result, the reduction rate of average maximal voluntary isometric contraction with assistance by the STSW device is about 51.2%. This means that users with the assistive device can stand up by using only about half of muscular activation in the case of natural standing up.
