Virtual reality exergames for enhancing engagement in stroke rehabilitation: A narrative review

This narrative review focuses on upper-limb stroke rehabilitation and virtual reality (VR) exergaming interventions that seek to facilitate the rehabilitation process. We examine exergaming interventions from the perspective of diegesis ("narration"), an aspect often overlooked despite its significance in neuronal rehabilitation. The importance of diegesis and narrative engagement in rehabilitation exergames started becoming clear only recently, with findings in the field of neurology underscoring the impact of purpose-driven task engagement on neuroplasticity. We begin this review by examining various frameworks for stroke rehabilitation exergames and identifying the gaps in the existing literature. We continue with summarizing the literature on exergames in upper-limb stroke rehabilitation, emphasizing the contribution of diegesis on exercise motivation and engagement. Finally, we conclude this review by offering insights into the current state of research, along with future perspectives on the topic.
