virtual environments and maneuvered through various social tasks such as interviewing, meeting new people, and dealing with arguments. Researchers found that participants improved in the areas of emotional recognition in voices and faces and in considering the thoughts of other people. Participants were also surveyed months after the study for how effective they thought the treatments were, and the responses were overwhelmingly positive. Many other studies have also explored this occupational therapy option. Attention deficit hyperactivity disorder A clinical trial published in the Journal of Attention Disorders found that school age children with ADHD who underwent a virtual classroom cognitive treatment series were able to achieve the same management of symptoms of impulsivity and distractibility as children who were medicated with a stimulant. Post-traumatic stress disorder It may also be possible to use virtual reality to assist those with PTSD. The virtual reality allows the patients to relive their combat situations at different extremes as a therapist can be there with them guiding them through the process. Some scholars believe that this is an effective way to treat PTSD patients as it allows for the recreation of exactly what they experienced. "It allows for greater engagement by the patient and, consequently, greater activation of the traumatic memory, which is necessary for the extinction of the conditioned fear." Stroke Virtual reality also has applications in the physical side of occupational therapy. For stroke patients, various virtual reality technologies can help bring fine control back to different muscle groups. Therapy often includes games controlled with haptic-feedback controllers that require fine movements, such as playing piano with a virtual hand. The Wii gaming system has also been used in conjunction with virtual reality as a treatment method. Chronic and acute pain Virtual reality (VR) has been shown to be effective in immediately decreasing procedural or acute pain. To date there have been few studies on its efficacy in chronic pain. Such chronic pain patients can tolerate the VR session without the side effects that sometimes come with VR such as headaches, dizziness or nausea. Rehab Virtual reality is also helping patients overcome balance and mobility problems resulting from stroke or head injury. In the study of VR, the modest advantage of VR over conventional training supports further investigation of the effect of video-capture VR or VR combined with conventional therapy in larger-scale randomized, more intense controlled studies. It shows the VR-assisted patients had
