What is an emg nerve test for hands

An EMG—electromyogram—is a test that checks the health of nerves and muscles. An EMG involves inserting tiny needles into your muscles to record electrical activity. Your doctor may recommend this nerve conduction study to help diagnose nerve and muscle diseases and seizures.

What to expect during your EMG test?

What to Expect During Your EMG Test. You are being sent to the electromyography (EMG) lab because you have numbness, tingling, pain, weakness, or muscle cramping. Some of the tests that Dr. Ellis may use to diagnose your symptoms are nerve conduction studies (NCSs), and needle EMG. Dr. Ellis will examine you to decide which tests to do.

What diseases can be detected by an EMG test?

10 Conditions Diagnosed With an EMG

  • Amyotrophic Lateral Sclerosis. Amyotrophic lateral sclerosis-ALS, or Lou Gehrig’s disease-is a progressive neuromuscular disease.
  • Carpal Tunnel Syndrome. Carpal tunnel syndrome affects the median nerve that runs through the wrist.
  • Charcot-Marie-Tooth Disease.
  • Lambert-Eaton Syndrome.
  • Muscular Dystrophy.
  • Myasthenia Gravis.
  • Peripheral Neuropathy.
  • Polymyositis.
  • What are the side effects of an EMG test?

    An EMG test is extremely safe. EMG needles are used for only one patient, are not recycled, and are immediately disposed of following use. Side effects may include some muscle soreness, which rarely lasts more than an hour or two after the exam.

    What are the benefits of having an EMG test?

    The test gathers information about both the muscular and nervous systems and is most helpful in determining if muscle weakness and pain are caused by muscle disease or nerve disease. EMG can also be helpful in identifying the muscle group that is most likely to provide useful information on biopsy.

    What to expect during an EMG?

    What you should know before an EMG test?

    Needle exam for muscle testing – Very fine needles are inserted into several muscles. Each needle has a microscopic electrode that picks up both the normal and abnormal electrical signals given off by a muscle. What you should know before an EMG test?

    What is EMG test Dr?

    During the EMG test Dr. Ellis will be able to hear and see how your muscles and nerves are working by the electrical signals made by your muscles. Dr. Ellis then uses her medical knowledge to figure out what could be causing your problem.

    Is an EMG an electrodiagnostic study?

    Electromyography (EMG) is a form of electrodiagnostic testing that is used to study nerve and muscle function. It is commonly performed by a physiatrist or neurologist with special training for this procedure. An EMG nerve test can provide your doctor with specific information about the extent of nerve and/or muscle injury…
