An Ergonomic Solution for Hand Rehabilitation Product Design for Stroke Patients

Rehabilitation training is a crucial part that helps stroke patients to train their muscles and rebuild the connection between muscle, nervous system and brain. This study conducts an ergonomic redesign of hand rehabilitation products based on the interview investigation to the user behavior and psychology during the training rehabilitation. The driving part of the device was relocated from the palm to the back of the hand to enhance the experience of stroke subjects to grab objects. Moreover, the device can drive the user to have a positive attitude towards their rehabilitation by visualizing the training improvement. Body scan and 3D printing technologies were utilized to ensure the accuracy of the position of the electric stimulation pads on the hands. The design also enhanced the voluntary motor functions at the palm and the fingers. The research results will contribute in formulating the design criteria of hand rehabilitation training products for stroke subjects.
