Graded Motor Imagery: Graded Motor Imagery (GMI) is a rehabilitation process and has been used to treat chronic pain conditions and movement problems related to alterations in the nervous system such as CRPS, postamputation limb pain, and back pain. The patients are trained in monitored steps which increase in difficulty as progress is made. The three treatment components include left/right discrimination training, motor imagery exercises and mirror observations of the unaffected limb, appearing as the affected limb. The components are performed sequentially, but require a flexible approach to suit the individual patient. The imagined movements have been demonstrated to activate motor cortical areas similar to those activated in the actual execution of that movement.
