Can I drive home after EMG?

What diseases does a nerve conduction test show?

Diseases or conditions that may be checked with NCV include:Guillain-Barré syndrome. … Carpal tunnel syndrome. … Charcot-Marie-Tooth disease. … Herniated disk disease. … Chronic inflammatory polyneuropathy and neuropathy. … Sciatic nerve problems.

Does nerve damage show up on MRI?

MRI is sensitive to changes in cartilage and bone structure resulting from injury, disease, or aging. It can detect herniated discs, pinched nerves, spinal tumors, spinal cord compression, and fractures.

How long does a nerve conduction study take?

Nerve conduction studies are usually done before an EMG if both tests are being done. Nerve conduction testing takes 15 minutes to an hour or more, depending upon how many areas are studied.

Is a nerve conduction test painful?

You may feel some discomfort depending on how strong the impulse is. You should feel no pain once the test is finished. Often, the nerve conduction test is followed by electromyography (EMG). In this test, a needle is placed into a muscle and you are told to contract that muscle.

What should you not do before a nerve conduction study?

Tell your doctor if you have bleeding problems or take blood-thinning medicine, such as warfarin (Coumadin) or heparin.

What does a normal nerve conduction test rule out?

NCV tests can measure the speed and strength of nerve signals. Nerve conduction velocity between 50 to 60 meters per second is considered normal. A damaged nerve may send a slower and weaker signal than a healthy one. It is possible to have normal results even if a person has nerve damage.
