Effects of Immersive Virtual Reality on Balance of Parkinson's Disease

Study Backgroud and Rationale: Parkinson's disease (PD) is one of the most common neurogenerative disease. Parkinson's disease is one of the most common neurodegenerative diseases. Patients suffering from it present a series of motor symptoms, including resting tremors, hyperresistance, bradykinesia, postural instability, and gait disturbances. Postural instability leads to an increase in the number of falls, which leads to greater dependence and social isolation, resulting in a reduced quality of life. Usual physical therapy techniques show an improvement in the motor skills of people with PD; however, their effectiveness is sometimes limited by patient adherence. Objective: The primary objective of this study is to determine whether the Immersive Virtual Reality (IVR) program rehabilitation can improve the balance of people with PD by Mini-Balance Systems Test (Mini-BESTest). Secondary objectives included assessing changes in gait speed, lower limbs strength, functional mobility, quality of life, adherence to the treatment and the possible occurrence of adverse symptoms during the use of IVR. Study Design: This is a single-blind, randomized clinical trial. Fifty patients with PD will be recruited and randomly assigned to either the control group, wich will receive balance conventional physiotherapy rehabilitation thought or the intervention group, wich will receive a IVR program rehabilitation. Both groups will undergo a comprehensive rehabilitation program that will include: active mobility exercises, strength exercises for the main antigravity muscles, and active stretching of the main muscles of the posterior chain. Methodology: There will be eight 40-minute sessions over four weeks. The first 20 minutes will be the same for both groups, while the second part of the session will vary between the control group (standard physical therapy) and the intervention group (IVR).
