The purpose of this study were to examine the effect of high intensity, low frequency transcutaneous electrical nerve stimulation at auricular acupuncture points on experimental pain threshold measured at the wrist and to determine the changes in effect over time. Forty-two healthy adult men and women were assigned randomly to one of three treatment groups. Group 1(n=15) received TENS to appropriate auricular points for wrist, Group 2(n=12) received TENS to wrist, and Group 3(n=15) received no TENS. We measured experimental pain threshold at the wrist after an electrical stimulus during one pre-treatment and three post-treatment time periods. Group 1 and 2 showed stastically significant increase(p<0.05) in pain threshold after treatment whereas the Group 3 did not. Group 1 showed a significant increase in pain threshold than Group 2. These results suggest that high intensity, low frequency TENS applied to appropriate auricular acupuncture points can increase pain threshold.
