Chronic musculoskeletal pain is defined as persistent or recurrent pain lasting more than 3 months. Chronic pain is a complex and disabling physiological and psychosocial disorder that does not provide an adaptive or protective purpose. In chronic pain, the precipitating event (e.g., fracture, sprain, trauma) is healed, and yet excessive pain remains. In Immersive Virtual Reality (IVR) people experience a three-dimensional, computer-generated environment via a computer headset. IVR has been used to treat acute pain, but there have been few focused studies on the effects of IVR on chronic pain. When people with chronic pain are in IVR, they become unaware of their body and tend to move normally. We would like to test to see if IVR has a lasting effect in this study. Thus, IVR has strong potential as an additional tool in an arsenal of treatments for chronic pain. This study will examine if IVR can reduce pain and other symptoms in people with chronic pain.
