The reported values of laboratory data represent the mean (standard deviation).
NCV = nerve conduction velocities.
*The mean data are out of normal range for this NCS laboratory. The normal ranges in this NCS laboratory were: sural NCV 41.5–58.3 m/s, sural amplitude 5–37.16 μV, median sensory NCV 48.7–65.5 m/s, median sensory amplitude 10.0–72.6 μV, median motor NCV 49.2–64.8 m/s, and median motor amplitude 3.0–15.4 mV.
