Abstract
In recent years, many wearable power assist suits to support human movements have been developed and these most assist the rotation of the hip joints. In care work, when holding a person and transferring from a bed to a wheelchair, the burden of the upper limbs is heavy. Therefore, to reduce the burden on the during transferring operation, we developed power-assist technology consisting of a wearable exoskeleton that holds the posture of the elbow joint. We performed primary evaluation and it confirmed that the amount of muscle activity in the upper arm was reduced by using this technology．
