免荷型パワーアシスト装置を用いた持ち上げ支援時の経時的な筋負担評価

抄録

We developed two types of non-wearing power assist devices that allow the squat method. One is a pneumatic power assist device that uses a pneumatic actuator, the other is a passive power assist device that uses only springs. The support effect and muscle burden over time were evaluated using EMG and floor reaction force through lifting motion support experiments for these devices. From the experiment result, it was confirmed that the muscle burden on the lower body of the subject were significantly reduced, which prove the effect on one-side support using both non-wearing assist device.
