Preliminary Results from a Six-Week Home-Based Evaluation of a Rehabilitation Device for Hand and Wrist Therapy After Stroke

Abstract

While many robot-aided solutions have been proposed for the rehabilitation of the distal segment of the upper limb, very few take into account the synergy between the wrist and fingers to allow them to train simultaneously in a home environment. WiGlove is a passive robotic orthosis designed to address this need. This wearable, wireless device enables stroke survivors to perform flexion/extension exercises of both the wrist and fingers while performing ADL or playing therapeutic computer games. As a part of its user-centred design process, this paper presents a case study of a 6-week feasibility evaluation of the WiGlove conducted at a stroke survivor's home without assistance from the therapists. The participant trained with the device for an average of 48 minutes a day and showed a noticeable reduction in the spasticity of the fingers and improved performance in the box and block test. He expressed satisfaction with its usability and suitability for the home environment. These results show overwhelmingly positive outcomes in terms of its acceptance, usability and effectiveness in offering home-based rehabilitation of the wrist and fingers.
