PURPOSE
To conduct a median nerve conduction study on patients with carpal tunnel syndrome and investigate the relationship between nerve conduction study parameters and clinical grading.
METHODS
A nerve conduction study was performed on 60 upper limbs of 37 patients with idiopathic carpal tunnel syndrome, and the relationship between the clinical grade and various study parameters was assessed.
RESULTS
The amplitude of the sensory nerve action potential and the motor nerve action potential differed according to clinical grading, but this pattern was not seen for sensory nerve conduction velocity, motor nerve conduction velocity, or motor nerve terminal latency and clinical grading.
CONCLUSION
The amplitude of the sensory nerve action potential and motor nerve action potential reflect the functional state of axons, and are useful parameters for assessing clinical grading based on nerve conduction velocity.
