Comparison of orthodromic and antidromic sensory nerve conduction velocity measurements in the carpal tunnel syndrome.
Orthodromic and antidromic nerve conduction velocities were determined in sensory median nerve fibres from digit to palm and from palm to wrist in patients with the carpal tunnel syndrome. In a large number of subjects the carpal tunnel syndrome could be detected only when the palm-to-wrist segment was investigated. Comparison of the results of the corresponding orthodromic and antidromic nerve conduction velocity measurements along the different segments revealed no significant disadvantages for the antidromic method. This technique should be given preference to the orthodromic method since it is easier.
