Computerized mirror therapy with augmented reflection technology for stroke rehabilitation: A feasibility study in a rehabilitation center

Abstract

New rehabilitation strategies for post-stroke upper limb rehabilitation employing visual stimulation show promising results. Cost-efficient ways to provide these techniques are still a challenge. Virtual and Augmented Reality Technologies could be suitable for this endeavor. Recent technological advances often are not translated into therapeutic practice and improved outcomes for patients because of a lack of research on their practical usage, coupled with the inexistence of appropriate guidelines and protocols. Here we present a novel and affordable augmented reality system that was developed and evaluated in combination with a validated mirror therapy protocol for upper limb rehabilitation after stroke. We evaluated the components of the therapeutic intervention from both the patients' and the therapists' points of view. In particular, we provide evidence that the combination and application of the Berlin Protocol for Mirror Therapy together with Augmented Reflection Technology is feasible for clinical use. This paves the way to a broader use of technically-supported mirror therapy with the possibility of higher therapy frequencies and enhanced recovery for patients.
