The Effect of Virtual Reality (VR) Versus Conventional Vestibular Rehabilitation and Progressive Muscle Relaxation (PMR) to Improve Balance and Stress Among Patients of Persistent Postural Perceptual Dizziness (PPPD).

A will be treated by progressive muscle relaxation (PMR) technique as a mean of stress relaxation and vestibular rehabilitation exercises for postural stability through Swiss ball, BOSU ball, balance board etc. Other components of vestibular rehab including gaze stability enhancement, improvement in vertigo and activities of daily living will also be focused.

virtual reality (VR) based intervention program where three dimensional-3D environments will be used reduce stress and improve balance. A Simulator Sickness Questionnaire (SSQ) will be filled by participants before and after each session of VR to discriminate whether VR is provoking the symptoms or not.
