简要总结
The ReHandyBot is a robot for hand rehabilitation after stroke. The aims of this study are (1) to investigate the feasibility of unsupervised therapy with the ReHandyBot with stroke inpatients, first in a rehabilitation clinic and then at participants' home, (2) to evaluate the usability of the ReHandyBot (user interface, implemented exercises, and gaming environment, which were adapted for independent usage), and (3) to quantify the dose of additional robotic therapy that patients perform without supervision.
The study consists of two primary phases. The first is a familiarization phase performed at the clinic, where therapists teach to the participants how to perform the exercises with 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.

研究组 & 干预措施
Unsupervised therapy
This group will perform therapy with the ReHandyBot first with the supervision of a therapist at the rehabilitation clinic. Then, after discharge, if the participant learnt how to safely train with the device, they can bring the device home and train with it unsupervised. On the other hand, if participants are not capable of training without supervision, after discharge they perform unsupervised therapy at home with a booklet of exercises (i.e., without the robot).
