Neurodiagnostics

Electromyography and Nerve Conduction Testing is the electrical study of the peripheral nervous system and muscles, as well as connections from the peripheral nervous system to the central nervous system. This testing is performed using sophisticated and sensitive electrical equipment to determine presence or absence of nerve or muscle disorders. An EMG/NCS can help evaluate symptoms such as weakness, numbness, pain, fatigue, cramping and abnormal sensation within the arms, legs or face. Common conditions to look for include nerve impingement (such as carpal tunnel syndrome and pinched nerves in the neck or back), degeneration of nerves (such as neuropathy), and muscle diseases (such as muscular dystrophy and myopathy). Electrical testing of the peripheral nervous system can also include specialized testing to evaluate the connections of the nerves to the muscles (neuromuscular junction), and is useful in diagnosing conditions such as myasthenia gravis.
