An NCV, or nerve conduction velocity test, measures how fast electrical signals travel through a nerve. Slowing or reduced amplitude indicates nerve damage or compression. It is one of the most precise tools available for diagnosing peripheral nerve disorders including carpal tunnel syndrome, ulnar neuropathy, and radiculopathy. California Sports and Rehab performs NCV testing for Nerve Damage as part of a complete electrodiagnostic evaluation.
