Generalizability of Unsupervised Therapy After Stroke in the Home Setting With a Hand Rehabilitation Device (ReHandyBot) (RHB Home SNR)

23 giugno 2026 aggiornato da: Swiss Federal Institute of Technology

Generalizability of Unsupervised Therapy After Stroke in the Home Setting With a Hand Rehabilitation Device (ReHandyBot): a Multicentric, Exploratory Study

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.

Armi e interventi

Gruppo di partecipanti / Arm
Intervento / Trattamento
Sperimentale: 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 has learned how to safely train with the device, they can bring the device home and train with it unsupervised.
During the familiarization phase at the rehabilitation clinics, participants perform one week of supervised and one week of minimally supervised therapy with the ReHandyBot under the supervision of a supervisor (i.e., therapist or researcher). Minimally supervised therapy means that participants try to perform therapy with the device themselves, while the supervisor is still present but helps only if participants encounter problems or have questions. During the supervised and minimally supervised phases (first 2 weeks), the intervention consists of 5 sessions of approximately 30 minutes each per week. These sessions are performed in addition to the conventional therapy plan. During each session, the robot proposes a set of different exercises targeting the upper limb.
After the familiarization phase, participants train without supervision at the clinic until discharge and then at home for six weeks. If the therapist thinks that the participant has properly learned how to use the device and can train with it safely, the participant can keep training with the device unsupervised (both at the clinic and at home). If participants are not ready for unsupervised therapy with the device, they stop the study at the end of the familiarization phase.
