EMG ClinicElectrodiagnostic services include Electromyography (EMG) and Nerve Conduction Studies (NCS) and are used to diagnose nerve and/or muscle disease or injury. Disorders that may be evaluated by EMG/NCS include, but are not limited to,: Carpal tunnel syndrome, Ulnar neuropathy, Tarsal tunnel disorder, Foot Drop, Traumatic nerve injury, Cervical and Lumbosacral Radiculopathy, Brachial and Lumbosacral Plexopathy, Myopathies, Neuromuscular Junction Disorders, and Motor Neuron Diseases.
The test involves measuring the conduction along the nerve in various parts of the extremities. Generally, a test may take anywhere from 30 minutes to several hours depending on the degree of difficulty. A typical study lasts approximately one hour. Electrodiagnostic studies begin with a focused history and detailed physical examination. The initial component involves small electrical stimulations that assist with a measuring how fast signals travel along a nerve. The second part involves placing small pins into different muscles in the back, arms, or legs to assess the affect of the nerve on the muscle itself. Physicians complete all tests.
