Mirror Therapy Preceding Augmented Reality in Stroke Rehabilitation

Mirror Therapy Preceding Augmented Reality in Stroke Rehabilitation: A Cross-Setting Study

This proposed research is in line with the National Health Research Institutes (NHRI) Innovative Research Grant priority to address innovative treatment strategies for neurological disorders that are in desperate need of scientific scrutiny. Stroke is one of the major medical conditions that leads to long-term disability and causes a heavy health care and financial burden. To meet multiple needs of patients with stroke, hybrid interventions that combine different approaches and practices in different settings are needed based on the complexity of stroke. Our previous research funded by the NHRI has been published and translated to stroke rehabilitation. Extending our previous research, the investigators will study the benefits of novel rehabilitation regimens of mirror therapy preceding augmented reality as well as the effects of practice setting (i.e., clinic- vs. home-based settings). In line with the current trend for the development of mirror therapy, mirror therapy will be implemented based on the bilateral and unilateral approach. Augmented reality will be implemented as a means of exergaming with real-time feedback to motivate the patients with stroke for active participation. In addition, telehealth techniques will be used to monitor home practice. This research is innovative in the use of telehealth techniques that will meet the call for therapy outside of the clinical settings in the era of COVID-19 pandemic.

Current stroke rehabilitation programs, such as mirror therapy and augmented reality and their combination, are novel intervention approaches that have promise for feedback-enhanced stroke rehabilitation. Mirror therapy may contribute to bilateral brain coupling by means of mirror visual feedback. It can potentially be an effective priming technique for creating an enriched neuroplastic environment to facilitate motor and functional recovery. Augmented reality is powered by its potential to provide an intensive, repetitive, and context-rich training program and promote motor, mobility, and cognition function recovery. Mirror therapy and augmented reality can be complementary for formulating a hybrid regimen. Mirror therapy has been implemented conventionally by being based on a bilateral approach. Our innovative protocol will include both unilateral mirror therapy and bilateral mirror therapy using personally relevant task objects for improving task performance. In addition, the investigators will extend clinic-based practice to practice in the home environment by using telehealth techniques for monitoring performance and providing feedback. The goals of this proposed research project will be to examine the effects of the hybrid intervention of mirror therapy preceding augmented reality or conventional therapy on sensory and motor function, mobility, daily function, life quality, and self-efficacy in stroke patients; compare the effects of the hybrid regimen in the clinical versus the home setting; and identify the potential predictors of treatment success using machine learning techniques.
