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. Patients with numbness, tingling, weakness, fatigue, muscle twitching or cramping, or difficulty ambulating, may benefit from an EMG evaluation to further understand their 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. 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. 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.
