The current study attempts to utilize deep brain stimulation of the periaqueductal grey (PAG) for diminution of both neuropathic and nociceptive pain in spinal cord injury patients. Likewise, the study will look at the effects on autonomic function as well. Deep brain stimulation, as a treatment, has gained widespread use for the treatment of various movement disorders. It is currently approved for use by the FDA for treatment of Parkinsons Disease, Essential Tremor, and Dystonia. Over 100,000 implants have been performed worldwide for these indications. The safety profile is well defined.
