The Effect of Prolonged Use of a Wearable Soft-Robotic Glove Post Stroke - a Proof-of-Principle

Abstract

Many stroke survivors encounter difficulties in the performance of activities of daily life due to limitations in functional use of the hand. Robotic technology has the potential to compensate for this loss by providing the support that is required to perform activities of daily living, especially when these devices are wearable comfortably for many hours at home. As a first step towards the implementation of assistive technology in the homes of stroke survivors, usability along with the potential effect of prolonged use of a wearable soft-robotic glove during activities of daily life on functional task performance was assessed in this study. Therefore, five chronic stroke survivors were asked to use a wearable soft-robotic glove for four weeks at home during preferred activities of daily life. Before and after the home use of the glove, functional task performance was assessed in a lab environment. After the use of the glove, system usability was assessed. The prolonged use of the glove resulted in an improved supported and unsupported functional performance during tasks related to activities of daily life, as measured with the Jebsen-Taylor Hand Function Test. Promising system usability results were found indicating a good probability for acceptance of the glove. The results from this study indicate the potential of the current glove to be used as assistive tool, which even showed a therapeutic effect. Yet, the glove should be tested in a larger sample for better interpretation and confirmation of these promising results.
