Study of the thermal pain threshold latency of acupoints based on Fei Teng Ba Fa

Abstract

Objective

By applying moxibustion to the eight confluent points in different periods of time, to observe the changes in thermal pain threshold latency of acupoints based on Fei Teng Ba Fa.

Methods

A total of 468 healthy college student volunteers received moxibustion at the eight confluent points in three different periods of time, i.e. Chen (7:00-9:00), Wu (11:00-13:00) and Xu (19:00-21:00). The thermal pain threshold latency was adopted to measure the changes in pain threshold of the eight confluent points under different conditions (different periods of time, different genders, different acupoints and different states of the acupoints) based on Fei Teng Ba Fa.

Results

Finally, thirty subjects dropped out and 438 subjects were included. The comparison of thermal pain threshold latencies of the eight confluent points in the same opening or closing state based on Fei Teng Ba Fa: latencies of the closing points and adjunct points were significantly different in different periods of time (P<0.05); the latencies of the males were significantly longer than those of the females (P<0.05); there was no significant difference in the latency between the left and right sides (P>0.05); in the female group, there was a significant difference in the latency between the lower-limb points and the upper-limb points (P<0.05). The comparison of thermal point threshold latencies of the eight confluent points in different opening or closing state: in the period of Wu (11:00-13:00), the latencies of the opening points were significantly longer than those of the closing points and adjunct points (P<0.05); for men, their opening and closing points had significantly longer thermal pain threshold latencies than their adjunct points (P<0.05); despite the gender, the latencies of the upper limb opening and closing points were significantly longer than the latency of the adjunct points (P<0.05); in the female group, the latencies of the lower-limb opening points were significantly shorter than those of the lower-limb closing and adjunct points (P<0.05).

Conclusion

Based on Fei Teng Ba Fa, the pain thresholds of the eight confluent points vary in different periods of time, gender, acupoint location and opening/closing state, which can be taken as the evidence of making time-based acupuncture-moxibustion prescriptions.

摘要

目的

通过不同时辰艾灸八脉交会穴, 探析飞腾八法取穴时人体腧穴感热痛阈时间的变化。

方法

共名健康大学生志愿者, 分别于辰时(7:00-9:00点)、午时(11:00-13:00点)和戌时(19:00-21:00点)艾灸八脉交会穴, 采用感热痛阈时间评定在不同时辰、不同性别、不同腧穴部位和不同腧穴状态下飞腾八法按时取穴时八脉交会穴的痛阈变化。

结果

脱落、剔除30人, 最终纳入研究者438人。 飞腾八法按时取穴时,八脉交会穴在相同开阖状 态下感热痛阈时间比较:不同时辰的闭穴、配穴存在统计学差异(P<0.05); 男性痛阈时间显著长于女性(P<0.05);左侧与右侧无统计学差异(P>0.05); 女性的下肢穴位与上肢穴位有统计学差异(P<0.05)。 八脉交会穴不同开阖状态下感热痛阈时间比较: 午时开穴的痛阈时间显著长于闭穴和配穴(P<0.05);男性的开穴、闭穴痛阈时间显著长 于配穴(P<0.05);男女上肢的开穴、闭穴痛阈时间均显著长于配穴(P<0.05); 女性下肢开穴的痛阈时间显著短于闭穴和配穴(P<0.05)。

结论

飞腾八法取穴时, 八脉交会穴的痛阈因时辰、性别、腧穴部位和腧穴开阖状态而异, 可作为按时针灸处方的实验依据。
