Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

There is paucity of literature in studying the comparative effects of Vestibular Rehabilitation and Virtual Reality. This study will determine the effects of these interventions on dizziness, balance and gait. This study will also deduce the role of vestibular rehabilitation and Virtual reality in subacute stroke patients

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Stroke is defined as rapidly developing clinical signs of focal disturbance of cerebral function that lasts more than 24 hours or leading to death. It arises from vascular causes such as cerebral infarction, intracerebral hemorrhage or subarachnoid hemorrhage. Stroke refers to any damage to the brain due to abnormality of blood supply. Stroke patients have difficulty in maintaining balance and postural control because they have asymmetric posture, abnormal body imbalance and difficulty in weight transfer.

Balance is required to maintain posture, to respond to voluntary movements and react to external perturbations. Because of the balance disorders, compensatory movements occur in stroke patients which causes them to consume more energy compared to healthy subjects and causes the development of inefficient walking pattern.

Gait function determines the degree of physical ability of post-stroke patients and their ability to perform independent mobility during activities of daily living (ADL). Stroke patients acquire compensatory abnormal walking pattern as a result of muscular weakness and inability to maintain balance.

Virtual reality rehabilitation systems provide direct sensorial feedback to which a person can respond and interact with environment. VR environments are commonly used in treating, training, and rehabilitation of stroke patients. In virtual reality rehabilitation, the patient moves and performs predetermined tasks as if he is performing the actions in reality.

According to a study conducted by Hyung Young Lee, Virtual reality-based training has been used as therapeutic intervention for functional recovery of stroke patients. It provides a variety of environments based on the requirements of patients that can be selected for recovery.

According to a study conducted by Yurong Mao, Virtual reality balance training provides more realistic proprioceptive and visual input and improves balance and gait function effectively. Virtual reality balance games can be used as an effective tool to train patients with balance dysfunction.

Literature describes Virtual Reality training is effective in improving dynamic balance control and preventing falls in subacute stroke patients. Virtual reality training provides stroke patients with planned and consistent exercises to improve balance and gait by giving visual feedback to directly adjust their wrong weight center and shift visually.

Its reported that Vestibular rehabilitation is frequently used treatment for dizziness and balance problems. Vestibular Rehabilitation is a combination of different exercise components with an aim to improve gaze stability, balance and gait and facilitate somatosensory integration. It is used in treatment of stroke patients to improve dynamic balance by acting on the vestibular system, thus facilitating recovery.

A study indicated that, the main components of vestibular rehabilitation are gaze stabilization exercises to help adapt the VOR function and balance exercises to retrain the vestibulospinal reflex function. Thus, simultaneously measuring changes in the VOR function and gait performance before and after intervention will provide valuable information for rehabilitation.

Vestibular system plays a phase dependent role in gait and is active at certain points in the gait cycle including double support, changing direction, and step termination.

VRT is patient dependent and progression of the exercises depends upon individual patient's sensorimotor, cognitive, and emotional aspects.
