Electrodiagnostic Studies Law and Legal Definition
An Electrodiagnostic study is the testing of neuromuscular functions in which nerve conduction tests and needle electromyography are utilized.[ MCLS § 333.17001].
The two electrodiagnostic procedures most commonly performed are nerve conduction studies (NCS) and needle electromyography (EMG). Nerve conduction studies are used to assess the health of a nerve. Needle EMG is used to assess the health of a muscle. Electromyography studies are conducted to find out injury or disease of muscle, nerve roots, and peripheral nerves. Condition of the nerves from the spine, face, and extremities, including the foot and hand is tested. These studies are performed as a workup for complaints of pain, weakness, numbness, or tingling. However, an electrodiagnostic study does not include the use of surface electromyography.
