The ReHandyBot (RHB) is a robot for hand rehabilitation after stroke. The aims of this study are to investigate (i) the generalizability of unsupervised therapy with the ReHandyBot within patients' home after discharge from a clinic, (ii) compliance, as measured by the amount of unsupervised robot-assisted therapy dose (e.g., therapy time) performed by the subjects after discharge, (iii) the usability of ReHandyBot and user experience during robot-assisted therapy, and (iv) the effect of the increase in therapy dose achieved with our device compared to standard care. The study consists of two primary phases. The first is a familiarization phase conducted at the clinic, where therapists teach participants how to perform the exercises using the robot. Then, if capable of training with the robot safely, after discharge from the clinic, participants can bring the robot home and autonomously train with it. The hypothesis is that unsupervised therapy might be a possible way to increase therapy dose for stroke patients, with the potential to further improve recovery of hand function, with minimal additional burden for therapists and for the healthcare system.
