耳穴埋豆皮质下、神门、肾上腺穴对健康人痛阈的影响

Effects of ear seed acupressure at the subcortex,Shenmen(TF4)and adrenal gland points on pressure pain thresholds and pain tolerance in healthy individuals

目的探讨耳穴埋豆对健康人痛阈的影响。方法60例均为2021年1月—2021年3月就读于北京中医药大学在校生,采用随机数字表法将入组受试者随机分为试验组30例、对照组30例。试验组采用皮质下穴、神门穴、肾上腺穴耳穴埋豆,对照组受试者采用假耳穴埋豆。分别于第1次耳穴埋豆干预前、干预后15 min、30 min、1 h,以及干预7 d、14 d,测量压痛阈值和耐痛阈值。结果2组不同时间点压痛阈比较结果显示:干预15 min后至干预第7天,试验组压痛阈值逐渐升高,不同时间点间差异有统计学意义(F时间=39.526,P<0.05);2组间压痛阈差异有统计学意义(F_(组间)=1.211,P<0.05);耳穴埋豆干预与时间产生的交互因素对受试者压痛阈有影响(F_(交互)=29.831;P<0.05)。2组不同时间点耐痛阈比较结果显示:干预15 min后至干预第7天,试验组耐痛阈值逐渐升高,不同时间点间差异有统计学意义(F时间=18.805,P<0.05);2组间耐痛阈差异有统计学意义(F_(组间)=0.251,P<0.05);耳穴埋豆干预与时间产生的交互因素对受试者耐痛阈有影响(F_(交互)=14.914;P<0.05)。结论耳穴埋豆有助于提高健康人痛阈水平,镇痛效果较好。

Objective To investigate the effect of ear seed acupressure on pressure pain thresholds and pain tolerance in healthy individuals.Methods 60 students of Beijing University of Chinese Medicine were enrolled in this study from January 2021 to March 2021,and the participants were randomly divided into the experimental group(n=30)and the control group(n=30)by the random number table method.The experimental group received the auricular acupressure at the subcortex,Shenmen(TF4),and adrenal gland points on their ears,and the subjects in the control group received the technique at false points.The pressure pain thresholds and pain tolerance were measured before and 15 min,30 min,1 h after the first intervention,and 7 and 14 days afterwards.Results The comparison result of pressure pain thresholds at different time points in the two groups showed that the pressure pain thresholds of the experimental group gradually increased after 15 min to the 7th day,and the difference between the time points was statistically significant(F_(time)=39.526,P<0.05).There was a significant difference in pressure pain thresholds between the two groups(F=1.211,P<0.05).The interaction between the acupressure and duration had an effect on the pressure pain thresholds(F_( interaction)=29.831;P<0.05).The result of the comparison of pain tolerance at different time points in the two groups showed that the pain tolerance of the experimental group gradually increased after 15 minutes of intervention to the 7th day,and the difference between different time points was statistically significant(F_(time)=18.805,P<0.05).There was a significant difference in pain tolerance between the two groups(F=0.251,P<0.05).The interaction between the intervention and duration had an effect on the pain tolerance(F_(interaction)=14.914;P<0.05).Conclusion Auricular acupressure with vaccaria seeds can help improve the pressure pain thresholds and pain tolerance of and thus exert an analgesic effect on healthy people.
