Therapeutic effectiveness of virtual reality-based exercise through Oculus Quest 2 on balance, dizziness, nystagmus, and quality of life in patients with posterior canal benign paroxysmal positional vertigo - a randomized control trial protocol

Abstract

BPPV (benign paroxysmal positional vertigo) is one of the most prevalent causes of vertigo.The clinical features include nausea, imbalance, nystagmus, light-headedness, dizziness, fear of fall. Various exercises and maneuvers have been proved to be beneficial till date. Many technologies had also contributed in the physical rehabilitation. Virtual rehabilitation using virtual reality (VR) is a novel innovation in therapy. Virtual reality is widely used in treating the patients and adding to get back to their day-to-day life. Occulus quest 2 is a VR device. Depending on the patient's motions, Oculus Quest enables you to interact genuinely while immersing yourself in a virtual reality. BPPV is a very common condition and Posterior canal BPPV (PC-BPPV) is commonest of all. Most of the available literature targets conventional treatment including Exercises for repositioning and adaptation of otoconia. Comparative studies between the conventional rehabilitation protocols have also been done. There is paucity of research on virtual rehabilitation in PC-BPPV. VR utilizing Oculus Quest 2, a device designed to incorporate VR environment can be used to mobilize the patients head position there by repositioning the otoconia. Lack of evidence related to Virtual rehabilitation and specifically Oculus Quest 2 emphasises the need to study its effects on BPPV outcomes like balance, dizziness, quality of life and nystagmus. In this study, an attempt is made to use the oculus quest 2 for BPPV rehabilitation in addition to standard treatment. Patients will be divided into 2 groups control and experimental. Control group will receive Brandt-droff exercise on the other hand experimental will receive occulus quest 2 game “Coaster combat” in adjunct to the conventional. Berg balance scale, nystagmus time quality of life, dizziness handicap index and vertigo symptom scale are the outcomes. Outcomes will be assed at baseline and after 4 weeks.
