Lower extremity sensory nerve conduction studies.

The need for routine recording of sensory potentials in the lower extremity was developed in efforts to better investigate peripheral neuropathy. Sensory nerve conduction studies (NCS) are more sensitive to many abnormalities in the peripheral nervous system than the motor NCS responses. This article provides a thorough review of sensory nerve conduction studies of the lower extremity, with special emphasis on electrodiagnostic issues.
