Method for eradicating pain of central origin resulting from spinal cord injury
First Claim
1. A method for minimizing central pain in a patient having a spinal cord injury, the method comprising:
- determining the level of injury in the patient;
determining the location of perceived central pain in the patient;
mapping the location of the perceived pain in the patient to a potential pain generating DREZ of the patient'"'"'s spinal cord, the mapping consistent with a pre-determined somatotopic map, wherein the somatotopic map provides a standard guide for a DREZ location that correlates to a perceived central pain, as previously determined from a series of test subjects having spinal cord injuries; and
surgically exposing and causing one or more lesions in the identified pain generating DREZ, wherein the one or more lesions minimizes central pain in the patient and wherein each lesion in the pain generating DREZ site(s) is introduced by radio-frequency microcoagulation at about 90 degree C. for 30 seconds.

Abstract
Methods are provided to reliably identify and surgically eradicate aberrant DREZ in patients suffering from spinal cord injury. The methods include identifying potential aberrant DREZ using a combination of mapping techniques based on the location of the patients perceived pain, analysis of the spontaneous electrical hyperactivity in targeted DREZ, and analysis of evoked transcutaneous C-fiber stimulation both in pre-operative and operative conditions. Methods are also provided for identifying potential pain effecters in aberrant DREZ, useful in the preparation of non-invasive therapeutics for central pain characteristic of spinal cord injury.
