Objective: To evaluate the normal values of current perception threshold (CPT) and the difference of CPT between different age groups, both sexes and different body parts. Method: We have recorded CPT studies in 111 normal Korean adults. CPT was measured at the 1st and 5th finger along with the 1st and 5th toe by delivering several repetitions of three different frequencies (2000 Hz, 250 Hz and 5 Hz) of currents. Results: The mean CPT showed significant correlation with age, sex and body parts at 2000 Hz (p<0.05). Old age, male, and the toe were factors that resulted in mean CPT increase at 2000 Hz. When stimulated at 250Hz, the correlation in CPT was observed only at the 5th finger with age but did not show any correlation with sex (p<0.05). At 5Hz, the negative correlation in CPT was observed at the 1th toe with age (p<0.05). Conclusion: In this study, we are able to report normal CPT reference values and we hope our result can be a useful reference value for interpretation of CPT results.
