Nerve Conduction Velocity (NCV)

Nerve Conduction Velocity (NCV) study is a test to evaluate the functional  integrity of the nerves that connect the central nervous system to the body’s muscles. If the peripheral nerves in the limbs and the trunk are weak or have degenerated then the impulse that is generated in the brain to contract the body’s  muscles  to maintain postural stability especially that of the legs  (or even sometimes that of the arms) are inadequate and contraction of the body’s muscles are not enough to keep the body erect and steady. Such subjects feel unstable and are likely to fall. The NCV test is essential in all patients who have instability and feel like falling or complain of trembling or weakness of the legs or complain that they are floating or walking on cotton . This is basically a neurological test carried out by trained neuro-electrophysiologists  and evaluate whether the nerves of the arms and legs are functioning normally or not.
