Evaluating home-based technology for self-managing upper extremity rehabilitation at home by individuals with stroke - To prepare for a rigorous efficacy trial, the purpose of this “intervention development” research project is to refine the key features of the novel mRehab system to ensure that it aligns with user needs and improves user engagement and assess performance changes following use of the refined mRehab system in comparison to FitMi, a commercially available system. To address this purpose, the following aims are proposed: (1) assess user engagement with the mRehab system by: (a) assessing usability and functionality of the mRehab system, and (b) identifying features and characteristics of the mRehab system that act as barriers and facilitators of user engagement to refine the system, (2) evaluate the effectiveness of the system compared to FitMi, a commercial system, and (3) establish the required elements (participant recruitment, retention, outcome measures to be used) for planning an efficacy trial. Stroke survivors, clinicians, and experts in usable design for individuals with disabilities will be engaged at all stages of the project. Anticipated output of this project will be a be a refined mRehab system battery of assessments that holistically measure user engagement and establish the mRehab system as a post-stroke digital intervention. Continued long-term rehabilitation after stroke can lead to improved functional mobility and independence for stroke survivors. Over time, increased engagement with home-based mobility rehabilitation is expected to lead to greater independence with ADLs and, in turn, reduce the burden on the caregivers.
