The purposes of this study were 1) 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 2) to determine the changes in effect over time. Forty-four 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 pain, Group 2 (n = 14) received TENS to inappropriate (placebo) auricular points, and Group 3 (n = 15) received no TENS. We measured experimental pain threshold at the wrist after an electrical stimulus during one pretreatment and three posttreatment time periods. Group 1 was the only group that had a statistically significant increase (p less than .05) in pain threshold after testing. This increase remained significant for all posttreatment measurements for Group 1. These results suggest that high intensity, low frequency TENS applied to appropriate auricular acupuncture points can increase pain threshold.
1）研究在耳部穴位进行高强度、低频经皮电神经刺激对腕部实验性疼痛阈值的影响；2）确定效果随时间的变化。44名健康成年男女被随机分配到三个治疗组之一。第1组（n = 15）接受针对腕部疼痛的耳部穴位的经皮电神经刺激，第2组（n = 14）接受针对不适当（安慰剂）耳部穴位的经皮电神经刺激，第3组（n = 15）不接受经皮电神经刺激。在一个预处理时间段和三个治疗后时间段内，我们在电刺激后测量了腕部的实验性疼痛阈值。第1组是唯一在测试后疼痛阈值有统计学显著增加（p小于0.05）的组。对于第1组的所有治疗后测量，这种增加仍然显著。这些结果表明，应用于适当耳部穴位的高强度、低频经皮电神经刺激可以提高疼痛阈值。
