The doctor will look at and listen to the electrical signals that travel from the needle to the EMG machine. The doctor tests only the muscles necessary to decide what is wrong. There may be a small amount of pain when the needle is put in. A new needle is used for each patient, and it is thrown away after the test. What happens during needle EMG testing?įor this test, a small, thin needle is put into several muscles individually to see if there are any problems. These shocks cause a quick, mild, tingling feeling. This is done by applying small electrical shocks to the nerve and recording how the nerve works. NCS show how well the body’s electrical signals are traveling in a nerve.

What do nerve conduction studies (NCS) show? The doctor will examine you to decide which tests to perform. Some of the tests that the EMG doctor may use to diagnose your symptoms are NCS and needle EMG. You are being sent to the EMG Lab because you have numbness, tingling, pain, weakness or muscle cramping. Why am I being sent to the EMG Lab for tests? Joseph’s is a Board-certified Neurologists with subspecialty training in electrodiagnostic medicine. Who performs the needle electromyography (EMG) and nerve conduction study (NCS)? NM medicine requires training and knowledge beyond that expected of a general neurologist or physiatrist. The PNS includes the motor and sensory neurons, peripheral nerves, NM junctions, and muscles. NM medicine is the practice of medicine that involves the care of adult and pediatric patients with disorders of the peripheral nervous system (PNS) and its connections with the central nervous system. The results are combined with the patient’s clinical history and physical exam in order to diagnose and treat neuromuscular, musculoskeletal and nervous system disorders. EMG/NCS Electromyography & Nerve Conduction Studies Electrodiagnostic MedicineĪ specially-trained physician conduct tests that record and analyze electrical impulses between the nerves and muscles. Patients with numbness, tingling, weakness, fatigue, muscle twitching or cramping, or difficulty ambulating, may benefit from an EMG evaluation to further understand their disorders. Common and advanced techniques are used in the diagnosis of neuromuscular disorders, including radiculopathy (pinched nerves), carpal tunnel syndrome, peripheral neuropathy, muscle disease (myopathy), amyotrophic lateral sclerosis (Lou Gehrig disease), Myasthenia gravis, and many others.

Joseph’s, which holds Laboratory Accreditation with Exemplary Status from the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM), provides state-of-the-art diagnostic testing and neuromuscular evaluations.
