The electrodiagnostic medicine studies are a direct extension of the neurological portion of the physical examination. The examination can be helpful in evaluating the causes of numbness , tingling, pain, muscle weakness, fatigue, and muscle cramping. Several types of tests are used to study nerve and muscle function. These usually includes nerve conduction studies (NCS) and electromyography (EMG).

The physician who perform the electrodiagnostic studies undergoes special training in electrodiagnostic medicine procedures. The knowledge and expertise gained from such specialized medical training maximizes the ability of the consultant to consider appropriate differential diagnosis in planning and performing the electrodiagnostic examination. The expertise enables the consultant to assist referring physicians in establishing a diagnosis, determining prognoses, and assisting in proper management.

The examination usually takes 20 to 60 minutes. There are no restrictions on activity before or after the testing and there are no lasting aftereffects.
