Nerve conduction velocity test also known as NCS, these tests discover the speed at which an electrical impulse travels through a nerve, helping to detect nerve damage. Three types of NCS include:
- - Motor: This type involves the stimulation of motor nerves so we can record the compound muscle’s action potential.
- - Sensory: This type electrically stimulates sensory nerves and records their action, or, in other words, their sensory nerve action potential(SNAP).
- - Mixed: This type mixes both motor and sensory testing techniques
During the procedure, we will first identify which nerves will be examined. Then, a recording electrode is attached to the skin above the nerve before placing a stimulating electrode elsewhere on the body. The nerve is then stimulated with a swift, mild shock, for a very short period of time.
