This paper describes some experiments concerning human motion patterns were carried out for adopting a metal hydride actuator to the transfer aid system. The results were evaluated from an ergonomic viewpoint in order to obtain the optimal parameters for transferring the elderly from a bed to a wheelchair and vice versa Sagittal plane kinematics, surface EMG obtained from lower limbs, ground reaction forces and foot pressure distribution were measured using a 3D-motion analyzer. From the experimental results, it was found that the motion of the transfer aid was smooth when the initial angle of the ankle was 70°. The best initial angle of the trunk was also found to be about 45° while standing from a bed. However, the initial angle of the trunk was best at 60° when a person was in the process of sitting down on a wheelchair. Furthermore, a knee pad which supports the lower limbs requires flexibility in the range of from 0.1 to 0.2 kgf/mm.
