The cutaneous silent period in carpal tunnel syndrome

Objectives:
The cutaneous silent period (CSP), a sustained voluntary contraction following a painful stimulus applied over the appropriate dermatome produces a brief period of electrical silence, may be useful if the routine nerve conduction studies and needle electromyography are insufficient to diagnose entrapment neuropathies.
Material And Methods:
To investigate whether symptomatic or asymptomatic patients with entrapment neuropathies are differed in terms of CSP, one hundred fifty four hands of 58 patient and 19 controls were studied according to the clinical and electrophysiological findings.
Results:
CSP latency and duration could be affected in severe forms of entrapment neuropathies. However, even in patients with dysesthetic pain -which lead to the belief that small fibers may be involved-, results of electrophysiological evaluation could not support the clinical findings.
Conclusion:
In this study it was suggested that CSP studies provide no additional information in entrapment neuropathies.

Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
