Design and Evaluation of the Walking Cane Handle Grip

This study seeks to optimize the grip shape of canes used as walking aids. We developed a prototype shaped to reduce the dorsiflexion of the wrist joint, which we believe is a cause of wrist pain. The stability of the prototype grip is evaluated using a floor reaction force gauge based on a Nintendo Wii Balance Board [RVL-021]. The grips of conventional (S grip) and the prototype (P grip) cane were compared to find a significant difference in the behavior of anterior-posterior movement. These results indicate that the prototype showed good weight shift, and that the proposed grip design improved the stability of weight transfer during walking.
