Abstract

The purpose of this study was to examine the effect and $\beta-endorphin$ level as conventional transcutaneous electrical nerve stimulation (TENS) application on acupuncture paints. Twelve healthy adult male volunteers were participated in this study. The subjects were assigned to TENS group (n=6) and naloxone group (n=6). The LI 3 and M 10 meridian points of dominant arm were stimulated comfortably with 100 pps, $75{\mu}s$ conventional TENS for 30 minutes. Experimental pain threshold measurement and plasma $\beta-endorphin$ level were detected before and after conventional TENS application. Experimental pain threshold increased significantly (p<.01) but plasma $\beta-endorphin$ level was not change in TENS group. Experimental pain threshold increased significantly (p<.01) but plasma $\beta-endorphin$ level was not change in naloxone group. In this study, the conventional TENS induced analgesic effect, and plama $\beta-endorphin$ level was not increase concomitantly with analgesia. These results suggest that the $\beta-endorphin$ did not involved in conventional TENS analgesia.
