Formative Usability Evaluation of WiGlove - A Home-based Rehabilitation Device for Hand andWrist Therapy after Stroke

Abstract

WiGlove is a passive dynamic orthosis aimed at home-based poststroke rehabilitation of the hand and wrist. This paper highlights results from WiGlove's formative evaluation as the first step towards its deployment. In this study, twenty healthy participants evaluated the usability and safety of the WiGlove compared to its predecessor, the state-of-the-art SCRIPT Passive Orthosis (SPO). In this within-subject experiment, they performed various tasks such as donning/doffing, adjusting the tension, grasping, etc., with both gloves and rated them using a Likert scale-based questionnaire. The results showed improvements in several aspects of usability and safety. This study provides preliminary evidence of WiGlove's fitness for the next assessment with its intended users, people recovering from stroke with sustained hand and wrist impairment.
