NCV
Pronunciation: N-C-V
Also written as: NCV — Nerve Conduction Velocity
Nerve conduction velocity testing that measures the speed of electrical impulses through peripheral nerves.
Full Definition
Nerve conduction velocity (NCV) studies assess the function of peripheral nerves by measuring the speed and strength of electrical signals transmitted along nerve pathways. This diagnostic test complements EMG studies in rehabilitation medicine to localize and quantify nerve dysfunction. NCV testing involves electrical stimulation of nerves at specific points while recording responses from muscles or sensory receptors. Results help rehabilitation teams determine prognosis, plan appropriate interventions, and track recovery in conditions such as carpal tunnel syndrome, diabetic neuropathy, or traumatic nerve injuries.
Usage
Usage note: May be used interchangeably with NCS (Nerve Conduction Study) in clinical documentation.
