Electrodiagnosis of the carpal tunnel syndrome.

Electrodiagnosis of carpal tunnel syndrome.

This article discusses the historical aspects related to the understanding of carpal tunnel syndrome (CTS) and its diagnosis, highlighting observations about this disease that have yet to be challenged. This is followed by a discussion regarding the use of electrodiagnostic testing as a diagnostic tool for CTS, as well as the author's approach to making the diagnosis of CTS. Finally, conclusion...

Electrodiagnosis of the carpal tunnel syndrome.

In the carpal tunnel syndrome median nerve motor conduction may be delayed below the wrist, while the motor nerve fibre conduction velocity above-the wrist may be relatively unaffected (Carpendale, 1956; Simpson, 1956). Median nerve sensory conduction may also be impaired below the wrist in the carpal tunnel syndrome (Gilliatt and Sears, 1958). No detailed study has been made comparing distal s...

Value of F-wave studies on the electrodiagnosis of carpal tunnel syndrome

BACKGROUND F waves are late electrophysiological responses to antidromic activation of motor neurons and are used to evaluate the conduction along the whole length of peripheral nerves. We aimed to determine the diagnostic efficacies of minimum median nerve F-wave latency (FWL) and median-to-ulnar nerve F-wave latency difference (FWLD) on carpal tunnel syndrome (CTS). MATERIALS AND METHODS Th...

The carpal tunnel syndrome.

The carpal tunnel is a channel with fibroosseous walls leading from the deep flexor space of the forearm into the palm of the hand. Superficially it is bounded by the flexor retinaculum which stretches from the trapezium and scaphoid laterally to the pisiform and hamate medially. This tough sheet blends proximally with the deep fascia of the forearm and distally with the palmar aponeurosis. The...
