Nerve conduction studies and Electromyography
Nerve conduction studies show how well signals travel along a nerve and can help find the cause of abnormal nerve function. Small electric pulses to the nerve at one site and recording the response at a different place along the nerve. Response from the nerve is recoded by the machine. Usually several nerves in the arms or legs are tested depending on the history and examination.
Nerve conduction studies are usually followed by electromyography (EMG). This is to be done by a trained neurologist using a small Teflon coated electrode inserted into vaarious muscles in the extremities and some times the neck or back. Mild discomfort may be there with this procedure. Almost every one tolerates this well. This is a very useful test for pinched nerves and muscle disease.
Nerve conduction can be done with pacemakers, spinal cord stimulators or vagal nerve stimulators. Pregnancy is not a contraindication. There no adverse effects from this test.Test takes approximately 1- 1 ½ hours.
- 1. Do not put oil, vaseline or lotion on the limbs to be tested; otherwise we may have to reschedule
- 2.Wear loose garments or bring shorts if lower extremities are being tested. Gowns are available.
- 3.Inform if you are Coumadin (warfarin) as the needle examination cannot be performed.
