Increasing the dose of therapy administered to persons after neurological injuries may improve their functional outcome. Unsupervised robot-assisted therapy is one possible approach to support therapy along the continuum of care without overloading the healthcare system. This work summarizes the design of ReHandyBot, an active, portable device for upper limb rehabilitation targeting unsupervised use in the clinic or at home. Additionally, its preliminary usability evaluation by four stroke subjects who used the device for two weeks is described. The results showed that ReHandyBot is a suitable platform for implementing quality robot-assisted exercises, and stroke patients could use it with minimal supervision, rating its usability as excellent (mean score for the System Usability Scale > 85). This pilot study opens the door to a larger study with ReHandyBot aiming at increasing therapy dose after stroke.

摘要

Increasing the dose of therapy administered to persons after neurological injuries may improve their functional outcome. Unsupervised robot-assisted therapy is one possible approach to support therapy along the continuum of care without overloading the healthcare system. This work summarizes the design of ReHandyBot, an active, portable device for upper limb rehabilitation targeting unsupervised use in the clinic or at home. Additionally, its preliminary usability evaluation by four stroke subjects who used the device for two weeks is described. The results showed that ReHandyBot is a suitable platform for implementing quality robot-assisted exercises, and stroke patients could use it with minimal supervision, rating its usability as excellent (mean score for the System Usability Scale > 85). This pilot study opens the door to a larger study with ReHandyBot aiming at increasing therapy dose after stroke.
