Recent developments in the electrodiagnosis of radiculopathies.

The accuracy and reliability of electrodiagnosis in radiculopathy has improved in recent years. A better understanding of EMG findings coupled with the development of several tests that have recently become available in clinical practice (F wave studies, H reflex studies, and somatosensory evoked potential studies) have made it a valuable tool in the complete work-up for suspected radiculopathy. The use of this technique is reviewed and an illustrative case report is presented.
