The Lateral dorsal cutaneous branch of sural nerve (LDCB) is a terminal sensory branch of lower extremities. It can be injured frequently in peripheral nerves. However, the normal data of each component of nerve conduction study (NCS) of were not studied at this time. The Nerve Conduction Study of LDCB adults were assessed for amplitude, area, duration and nerve conduction velocity (NCV) in normal fifty. We also evaluated how age, sex and dexterity affect the various components of NCS. The Mean amplitude of LDCB was 9.45±1.93 μV, area was 4.05±0.55 μV/s, duration was 1.50±0.13 s, and NCV was 37.9±3.09 m/s, respectively. The amplitude of right was 10.1 μV in men, 8.65 μV in women. The area of right was 3.83 μV/s in less than 40 years and 4.24 μV/s in older than 40 years. The areas of left was 3.86 μV/s in less than 40 years and 4.30 μV/s in older than 40 years. The NCV was 39.0 m/s in less than 40 years and 36.7 m/s in older than 40 years. All of above differences were statistically significant. There were no statistically significant differences between right and left NCS. Normal data of LDCB could be applicable in peripheral neuropathy or nerve injury.
