Abstrakt:	Objectives: The aim of this study was to determine normative electrophysiological reference values of median sensory nerve conduction studies among security guards with the palmaris longus tendon (PLT). Methods: Sensory nerve conduction studies of the median nerve using antidromic and orthodromic methods were conducted in the upper limbs of 101 healthy male security guards between the ages of 21 and 42 years. The presence of the PLT was recorded in both hands using a standard test. A scatter plot was used to determine the correlation between different parameters using the ortho and antidromic methods. Results: The mean age (years), weight (kg), height (cm), and BMI (kg/m2) were 28.77 ± 5.14, 70.53 ± 11.28, 171.71 ± 7.12, and 23.91 ± 3.45, respectively. In the median nerve (sensory) by antidromic method, the mean distal latency (DL) was 2.65 ± 0.33 ms and 2.64 ± 0.37, SNCV (sensory nerve conduction velocity) was 53.45 ± 5.28 m/s and 53.84 ± 5.68 and the amplitude was 27.33 ± 12.38 µV and 29.41 ± 12.97 in the left- and right-hand wrist, respectively. By orthodromic method the DL was 2.54 ± 0.53 ms and 2.51 ± 0.44, SNCV was 55.93 ± 6.09 m/s and 55.93 ± 5.24 and the sensory nerve action potential amplitude was 12.00 ± 8.82 µV and 11.72 ± 6.24 in the left and right hand, respectively. Spearman correlations were used to determine the variables influenced by hand sidedness. Conclusions: The normative reference parameters of sensory nerve conduction velocity of the median nerve were established by both methods using a standardized technique.
