Electrodiagnostic medicine is the medical subspecialty that applies neurophysiologic techniques to diagnose, evaluate, and treat patients with impairments of the neurologic, neuromuscular, and/or muscular systems. Qualified physicians are trained in performing electrophysiological testing and interpretation of the test data. They require knowledge in anatomy, physiology, kinesiology, histology, and pathology of the brain, spinal cord, autonomic nerves, cranial nerves, peripheral nerves, neuromuscular junction, and muscles. They must know clinical features and treatment of diseases of the central, peripheral, and autonomic nervous systems, as well as those of neuromuscular junction and muscle. Physicians also require special knowledge about electric signal processing, including waveform analysis, electronics and instrumentation, stimulation and recording equipment, and statistics.

A physician who specializes in neuromuscular medicine possesses specialized knowledge in the science, clinical evaluation and management of these disorders. This encompasses the knowledge of the pathology, diagnosis and treatment of these disorders at a level that is significantly beyond the training and knowledge expected of a general neurologist, child neurologist or physiatrist.

Physical medicine and rehabilitation, also referred to as rehabilitation medicine, is the medical specialty concerned with diagnosing, evaluating, and treating patients with physical disabilities. These disabilities may arise from conditions affecting the musculoskeletal system such as neck and back pain, sports injuries, or other painful conditions affecting the limbs, such as carpal tunnel syndrome. Alternatively, the disabilities may result from neurological trauma or disease such as spinal cord injury, head injury or stroke. A physician certified in physical medicine and rehabilitation is often called a physiatrist. The primary goal of the physiatrist is to achieve maximal restoration of physical, psychological, social and vocational function through comprehensive rehabilitation. Pain management is often an important part of the role of the physiatrist. For diagnosis and evaluation, a physiatrist may include the techniques of electromyography to supplement the standard history, physical, x-ray and laboratory examinations. The physiatrist has expertise in the appropriate use of therapeutic exercise, prosthetics (artificial limbs), orthotics and mechanical and electrical devices.
