The electrodiagnostic (EDX) examination is an extension of the clinical examination. When used correctly it defines the location, pathophysiology, severity, and chronicity of a wide array of neuromuscular disorders. It is comprised of two parts: nerve conduction studies (NCS) and needle electromyography (EMG). While both portions are performed differently and have individual advantages and disadvantages, together they provide complimentary information on the integrity of the peripheral nervous system (Table 4.1). The needle EMG is most likely to be tolerated and helpful when the examiner uses a gentle and informed approach, wisely selects muscles to examine in order of greatest yield, and understands the value and limitations of this technique. |
