Abstract
Most stroke patients who have lost the ability to use their fingers do not recover the functions of the fingers in their activity of daily living (ADL). This paper presents a novel approach in finger rehabilitation for acute paralysed stroke survivors. Based on repetitive exercise concept, the device is designed to provide support for fingers to do flexion and extension movements according to the patients range of motion. A conceptual design of the device is proposed after considering the current mechanism and control from similar current devices published and commercialised. A comparison between 4 existing main working mechanisms: (1)Pneumatic Cylinders, (2)Artificial Rubber Muscles, (3)Linkage Mechanism, (4)Cable-Driven Mechanismis also provided in this paper. The key for designing the device is home-based practice, easy to use and affordable. Further investigation and experiments on the proposed: Cable Actuated Finger Exoskeleton (CAFEx) are currently still in progress.
