Laserpuncture is an acupuncture method for pain management. The goal of this study was to determine the effect of laserpuncture at the LI4 Hegu point on the plasma levels of β-endorphin in healthy subjects. A randomized, double-blind, controlled trial with placebo controls was conducted on 29 healthy subjects. Subjects were allocated into the laserpuncture group (n = 15) and the laserpuncture placebo group (n = 14). The plasma levels of β-endorphin were used to measure the output of the study assessed both before treatment and posttreatment. There are statistically significant differences in the mean plasma levels of β-endorphin before and after treatment in the laserpuncture group: changes in mean value from 0.22±0.06 ng/ml to 0.29±0.07 ng/ml with a p value = 0.005 (p < 0.05). There were no statistically significant differences in the mean plasma levels of β-endorphin before and after treatment in the laserpuncture placebo group: changes in mean value from 0.22±0.06 ng/ml to 0.26±0.09 ng/ml with p value = 0.195 (p > 0.05). Between groups, there was not a statistically significant difference in the baseline mean plasma levels of β-endorphin (p = 0.183, p > 0.05). The conclusion of this study is that laserpuncture can affect the plasma levels of β-endorphin in healthy subjects when there is no statistically significant difference in the mean plasma levels of β-endorphin between groups.
