Nerve Conduction Study and Electromyography(NCS/EMG) is a test designed to detect nerve and muscle disease. Your nerves and muscles have inherent electrical activity which is tested during a NCS/EMG study. Your physician will place surface electrodes on the skin and stimulate the nerves along its pathway with minor electric shocks. It requires about 45 minutes to an hour to complete, no preparation is required on your part. The EMG testing is done along with the NCS using a very fine, sterile needle that tests about 10-20 muscles depending on your condition. Do not apply lotion or cream on your skin prior to the test. You will be able to drive home or return to work after the test. The test is simple and does not cause damage or interfere with your pacemaker, deep brain stimulator or spinal cord stimulator.

NCS/EMG is used to diagnose Carpal tunnel syndrome, Ulnar neuropathy, Radial nerve palsy, brachial and lumbar plexopathy, motor neuron disease, myopathies, neuromuscular junction disorders and several other conditions.
