In order to standardize Nerve Conduction Velocity(NCV), proximal and distal latency and amplitude of motor conduction in intact accessory nerves, a cross-sectional, descriptive-analytic study was done on 60 healthy persons with strict attention to number of cases, distance between stimulation sites, temperature and age. The average results were as follows: Distal latency 2.54 milliseconds (msec.) (2.25-2.83), Proximal latency 3.64 msec. (3.34-3.94), Amplitude 13.76 millivolts (mv.) (8.56-18.96) and NCV 67.98 m/s (56.95-79.01). The average latencies in women were significantly less than men, on both sides which can be due to higher superficial skin temperature in women.
