Normal median nerve proximal latency in carpal tunnel syndrome: a clue to coexisting Martin-Gruber anastomosis.

Normal median nerve proximal latency in carpal tunnel syndrome: a clue to coexisting Martin-Gruber anastomosis.

Five of 65 patients referred for electrodiagnosis because of clinical evidence of carpal tunnel syndrome were found to have near normal latency on proximal stimulation of the median nerve, although the distal motor latency was prolonged. In one patient, the proximal latency was actually shorter than the distal latency. The failure of the proximal latency to be prolonged in proportion to the dis...

normal measures of median nerve motor and sensory latency in carpal tunnel syndrome

background : despite the high incidence and prevalence of cts, there is no exclusive data about normal values increment of motor and sensory distal latencies of median nerve at wrist according to age. this research was done in electrodiagnosis lab of physical medicine & rehabilitation ward in nemazi hospital in shiraz between 1374-1379. material and methods : this study was performed on 1200 ca...

Carpal Tunnel Syndrome and Median Nerve Lesions

Carpal tunnel syndrome (CTS) is by far the most common cause of median nerve damage. The carpal tunnel is an anatomical compartment of the hand; it is bounded on three sides by carpal bones which form an arch, and on the palmar side by the transverse carpal ligament. Pathogenesis CTS results from compromise of median nerve function at the wrist, caused by increased pressure in the carpal tunnel...
