A Qualitative and Usability Evaluation of Advanced Technologies for Home Upper Limb Neurorehabilitation Post-stroke

Tan Tock Seng Hospital30 enrolled

Overview

Due to limited resources such as the low therapist to patient ratio or high costs associated to rehabilitation therapy, providing higher therapy dose to patients after discharge is highly challenging. This often results in non-use of the impaired limb as a result of the decreased therapy dose, causing partial loss of the functional improvements previously gained during early rehabilitation. In this study, the investigators plan to pilot the HomeRehab Gym concept via the deployment of three rehabilitation devices at patients' homes: MyoPanda, H-Man and ReHandyBot.

Previous research has proven that technology-aided upper limb rehabilitation is non-inferior in terms of feasibility and efficacy when compared to conventional therapy in stroke patients. These rehabilitation devices can be set up as a 'rehabilitation gym' (RehabGym), where patients can interact with several devices that target different body and rehabilitation domains and, thus allows for a holistic and complementary therapy. Despite recent studies having shown that training with a RehabGym under reduced supervision in a hospital is not only feasible but also equally beneficial in terms of clinical outcomes, however, a RehabGym has never been set up at a patient's home to the best of our knowledge. This study aims to investigate the feasibility and safety of a RehabGym at home concept using three different upper-limb technologies (H-Man, ReHandyBot, MyoPanda) that are established, clinically tested and allow for on-demand therapy. Objective measures of clinical efficacy will also be examined, and cost-analysis to determine the economic feasibility of a commercial implementation of RehabGym at home in the future will be performed.

Interventions

H-Man RobotDEVICE

The HMAN is certified as a CE class 2A upper limb rehabilitation robot suitable for hospital, clinic and home-based use in 2020 by Health Sciences Authority, Singapore. It has since been employed in post-stroke neurorehabilitation therapy and assessment of sensorimotor functions in stroke patients.

ReHandyBotDEVICE

ReHandyBot is the portable version of ReHapticKnob a robot developed at ETH Zurich that provides neurocognitive therapy, focusing on hand opening and closing movements as well as prono-supination of the forearm.

MyoPandaDEVICE

MyoPanda is a passive wrist/hand device which patients use to train the hand and wrist function by controlling a virtual avatar with EMG activity measures.
