title: A practical electrophysiological guide for non-surgical and surgical treatment of carpal tunnel syndrome.
abstract: In the present study, we illustrate the use of an electrophysiological classification as a guide to the treatment of carpal tunnel syndrome (CTS). A total of 113 CTS patients were assessed with symptom severity scores, hand functional scores and electrophysiological studies. By setting criteria of electrophysiological tests, 179 hands in 113 patients were classified into mild, moderate and severe degrees of CTS. Of these, the 41 hands with severe CTS were referred for surgery. The 58 hands with moderate CTS and 80 hands with mild CTS received conservative treatment. The improvement ratios in the severe group were greater than that in the moderate and mild groups, both at 6 months and at 1 year. Eighteen hands with moderate or mild CTS returned to normal electrophysiology with the conservative treatments. No patient recovered to normal electrophysiology in the severe group. This electrophysiological classification is objective and it may serve as a useful guide for non-surgical and surgical treatment of CTS.
