WHAT'S BUZZING IN VR? Use of haptics in virtual rehabilitation of hand function after stroke: a literature review
Numerous virtual reality systems have been studied using different haptic devices to restore hand function post-stroke. These devices enhance immersion through the application of vibrotactile stimulation with kinaesthetic feedback. This multi-modal feedback has been theorized to improve motor control, strength, and dexterity in integration with the repetitive practice of an ecologically relevant motor task through the mechanism of neuroplasticity. Presently, haptic devices are unwieldy, expensive, and impractical for daily clinical use. Therefore, economical, petite, and ergonomically designed haptic devices may allow future studies to make stronger arguments for their inclusion in hand rehabilitation after stroke.
