Abstract

The muscle injuries of manual handling workers, caused by the repeated motion and heavy load in the daily tasks, strongly influence their quality of life. To prevent muscle injuries in many occupations, a close-fitting assistive suit weighing 0.75 [kg] with the passive actuation mechanism and adjustable structures is proposed to assist not only the back muscle but the arm muscle of manual handling workers according to the user intention. An experiment with electromyography for measuring the muscle activities is conducted with six subjects to practically confirm the effectiveness of the suit. The experimental results revealed and proved that the proposed suit can successfully and appropriately assist not only the arm but also the back muscle with a lifting-up motion, simultaneously.
