Complex regional pain syndrome (CRPS) is a form of chronic pain that usually affects an arm or a leg. CRPS typically develops after an injury, a surgery, a stroke or a heart attack. The pain is out of proportion to the severity of the injury. CRPS is uncommon, and its cause isn't clearly understood. With treatment,improvement and remission are possible.
Mirror therapy is a common treatment for CRPS. In mirror therapy, a mirror is used to create the illusion that movement has occurred without pain. It involves placing the affected limb behind a mirror. The mirror is positioned so the reflection of the opposing limb appears in place of the hidden limb. Mirror therapy is also used to treat phantom limb pain, and in stroke patients.
Mirror Therapy VR (name still in development) aims to improve and extend the emodiment illusion involved in mirror therapy by mirroring the unaffected limb in VR.
