others not using VR training. The most recent review about the effect of VR training on balance and gait ability showed significant benefits of VR training on gait speed, Berg Balance Scale (BBS) scores, and Timed "Up & Go" Test scores when VR was time dose matched to conventional therapy. Parkinson's disease Many studies (Cochrane Review) have shown that using VR technology during physical therapy treatments for patients with Parkinson's disease had positive outcomes. For patients with PD the VR therapy: Increased gait and balance. Improved functions of activities of daily living (ADL's). Improved quality of life. Improved cognitive function. It is speculated that these improvements occurred because the VR gave increased feedback to the patient regarding their performance during the VR sessions. VR stimulates a patient's motor and cognitive processes, both of which may be impaired as a result of the disease. Another benefit of VR is that it replicates real life scenarios, allowing patients to practice functional activities. Wound care Additionally, VR provides beneficial outcomes when it is implemented for patients who are receiving wound care rehabilitation. Studies have speculated that the more immersive the VR, the greater the experience and concentration the patient will have on the virtual environment. Equally important, VR has shown to reduce pain, anxiety and depressive symptoms, as well as an increasing their treatment adherence. In other studies, the results point to the benefits of VR in relation to increased distraction, and patients reported less time thinking about pain, less intense pain and immersion, which facilitates care such as dressing changes and physiotherapy. Wound dressing often generates a pain-provoking experience. Therefore, use of VR was related to more efficient dressings, increased distraction from the pain during procedures (e.g. dressing and physical rehabilitation) which reduced the patients' stress and anxiety. Cardiovascular The use of VR and video games could be considered as complementary tools for physical training in patients with Cardiovascular diseases. Certain games designed for exercise have been shown to promote increases in heart rate, fatigue perception, and physical activity. In addition, it has been shown to reduce pain and increase adherence to physical therapy programs in patients with cardiovascular diseases. Finally, virtual reality and video games enhance motivation and adherence in cardiac rehabilitation programs. Occupational therapy Autism Virtual reality has been shown to improve the social skills of young adults with autism. In one study, participants controlled a virtual avatar in different
