NCV -- Nerve Conduction Velocity
Tests the peripheral nervous system to the arms, legs, and face. This test checks both sensory and motor nerve fibers. Nerve conduction velocity studies diagnose different entrapment neuropathies, such as carpal tunnel syndrome, as well as ulnar, radial, peroneal, femoral, posterior tibial, and peripheral neuropathies. The test checks axonal loss, demyelination of the peripheral nerves, and conduction blocks. It is useful in diagnosing anterior horn cell diseases, as seen in amyotrophic lateral sclerosis, and neuromuscular junction problems, such as myasthenia gravis. The test differentiates inherited neuropathies such as Charcot-Marie-Tooth and Dejerine-Sottas entrapment neuropathies (avoiding multiple unnecessary surgeries).NCVs aid in the evaluation of:
- Herniated Disks
- Diabetic Neuropathy
- Peripheral neuropathies
- Numbness and tingling
- Pain in the extremities
- Atrophy
- Entrapment neuropathies
- Thoracic outlet syndrome
- Radiculopathies
- Carpal tunnel syndrome
- Tarsal tunnel syndrome
- Trauma to nerves
- Motor/sensory deficits
- Hot/cold sensation
- Neuritis
