EMG/NCS
Electromyography & Nerve Conduction Studies
About
Electromyography (EMG) and nerve condition studies (NCS) are tests that provide information about the health and function of the nerves and muscles in the arms and legs. These studies will help further evaluate symptoms you are experiencing such as numbness, tingling, pain, weakness, or muscle cramping.
EMG/NCS are valuable tools to diagnose the location and type of nerve or muscle disease, in order to establish an appropriate treatment. EMG/NCS testing is done in our Storm Lake office location.
Why?
A doctor will order this test for the following reasons:
Carpal tunnel syndrome
Peripheral neuropathy
Radiculopathy (pinched nerve roots)
Muscle disease
What To Expect During Your Test
The test has two parts:
PART 1 – Nerve Conduction Studies (NCS)
Part 1 takes approximately 30 minutes to perform. Small electrodes will be taped to your skin or placed around your fingers. Small electrical shocks are then applied to your arm or leg to evaluate nerve function. You may experience a mild and brief tingling or shock.
PART 2 – Electromyography (EMG)
Part 2 typically lasts 15-30 minutes. Small needles are inserted into selected muscles in your arm(s) and/or leg(s). The electrical activity of each muscle is then recorded. Analyzing the electrical activity of each muscle helps determine a diagnosis for your condition. You may experience mild discomfort when the muscles are stimulated.
