Sensory nerve conduction study in forearm segment of superficial radial nerve: standardization of technique.

Sensory nerve conduction velocity (SNCV) over the forearm segment of the superficial radial nerve was studied by an antidromic method in 76 nerves of 50 normal volunteers ranging in age from 16 to 70 years. The mean SNCVs were 53.3 +/- 3.6 m/sec (1 SD) and the mean amplitudes of sensory nerve action potentials were 15.2 +/- 9.8 microV (1 SD). This method of obtaining SNCV over the forearm segment of the superficial radial nerve is easily performed and the findings are consistent.
