nerve conduction study
A test measuring the speed and strength of electrical signals traveling through peripheral nerves.
Full Definition
A nerve conduction study (NCS) is a neurodiagnostic procedure that evaluates the function of peripheral nerves by measuring how quickly and effectively electrical impulses travel along nerve pathways. The test involves placing surface electrodes on the skin to stimulate nerves and record responses from muscles or sensory receptors. NCS is typically performed in conjunction with EMG to diagnose conditions such as carpal tunnel syndrome, peripheral neuropathy, Guillain-Barré syndrome, and other disorders affecting the peripheral nervous system.
Usage
Usage note: Often abbreviated as NCS in clinical documentation.
