Nerve Conduction Velocity (NCV) is a test commonly used to evaluate nerves, more commonly identifying large fiber neuropathy. An electrical current is used to stimulate the nerve. Since the nerve is in effect an electrical conduit, the time for the electrical impulse to travel to a site further along the nerve is measured. Normal values have been established, and comparison of your test to these values helps to indicate if there is damage to your nerves.
Electromyography (EMG) is typically an invasive technique, in which needles are inserted into your muscles. This test helps to identify disorders in the activation of muscles and their stimulating nerves, or neuromuscular diseases. Normal muscles at rest fall into certain ranges of electrical activity. Abnormal electrical activity might indicate some nerve and/or muscle damage.
Epidermal Nerve Fiber Density Testing (ENFD) In short, epidermal nerve fiber density testing involves taking a small “punch” of skin from the calf to visually count the number of nerve fibers. This allows a physician to identify small fiber peripheral neuropathy. Additionally, it also establishes an objective baseline so a physician can determine if treatments are effective.
