Game-Based Virtual Reality System for Upper Limb Rehabilitation After Stroke in a Clinical Environment: Systematic...

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Computer Science

Background:

• Virtual Reality (VR) has emerged as a significant tool in stroke rehabilitation over the last decade.
• Current research predominantly focuses on upper limb rehabilitation using VR, with limited exploration into VR game design and rehabilitation modalities.
• Stroke affects millions globally, necessitating innovative and effective rehabilitation strategies.

Purpose of the Study:

• To evaluate the efficacy of game-based VR for upper limb rehabilitation in stroke patients within clinical settings.
• To compare the impact of custom versus commercial VR games on patient rehabilitation outcomes.
• To review and categorize existing VR upper limb rehabilitation modes.

Main Methods:

• A systematic literature search was conducted across major databases (PubMed, ScienceDirect, Scopus, Web of Science, IEEE Xplore) for studies published up to December 2021.
• A meta-analysis was performed on 24 randomized controlled trials involving 793 adult stroke patients, comparing VR-based rehabilitation with conventional therapy.
• Outcomes analyzed included upper limb function, hand dexterity, daily living ability, and cognitive function.

Main Results:

• Game-based VR upper limb rehabilitation is a clinically effective therapy for stroke patients, outperforming traditional rehabilitation in enhancing upper limb function and hand mobility.
• Custom-designed VR games demonstrated superior rehabilitation outcomes compared to commercially available VR games.
• Non-immersive VR rehabilitation modes were analyzed and categorized, with potential for combining VR games with rehabilitation instruments to aid severely impaired patients.

Conclusions:

• Game-based VR therapy offers a significant advancement in stroke rehabilitation, particularly for upper limb recovery.
• The development and use of custom VR games should be prioritized for optimal patient outcomes.
• Future research should explore the impact of immersive VR devices and gamification on patient motivation and rehabilitation effectiveness.
