A Clinical Study Of The Association Between Primary Insomnia And Pain Threshold Response In The Back

[Objective]The purpose of this study is to observe the relationship between primary insomnia patients,and their positive pain threshold reaction points on the Du meridian(spine)and Back-Shu points.In order to find out whether there are regular and specific positive reactions points in the patients with insomnia and different types of insomnia.With the establishment of the "disease-acupoint specificity reaction" as the main line of the mechanism of acupuncture and moxibustion research framework,this study is conducted of further expound the scientific connotation of "acupoint specificity",lay a reliable foundation for clinical diagnosis and summarize the clinical treatment experiences of reliable meridian diagnostic theory.[Method]Volunteers had been recruited at the Guo Yi Tang outpatient department ofBeijing University of Chinese Medicine,three affiliated hospitals of Beijing University of Chinese Medicine and community hospitals.We recruited 117 people totally,aged between 20～85 years old.Firstly,we used T-scale weighing apparatus(Serial No.72814)for back acupressure test and all cases were recorded,finally we screened out 87 people(out of 97)who met all criteria,among them 32 men and 55 woman.Secondly,we recruited 20 healthy people,among them 9 men and 11 women.We did the back acupressure test and all cases are recorded again.The pain threshold value of acupoints of Du meridian and Back-shu are the main analysis indexs between those two groups.We have observed and explored the correlation between the positive reaction points and disease of primary insomnia patients and the insomnia patients with different syndrome.[Result]In comparison of the pain threshold of insomnia patients and healthy people,there were statistically significant differences in T3(DU12),T4,T5(DU11),L4(DU3),L5(EX-B8)sections of Du meridian(spine),and in T3(BL13),T5(BL15),T8(EX-B3),L3(BL24),L4(BL-25)sections corresponding to the position of the left Back-shu points,and in T3(BL13),T5(BL15),T8(EX-B3),T10(BL19),L1(BL-22)sections corresponding to the position of the right Back-shu Points.In comparison of the pain threshold of Du meridian(spine)of five types of insomnia patients,there were statistically significant differences in T9(BL18),T10(BL19)segments of group of stagnation of liver fire syndrome;and in T8(EX-B3)segments of group of phlegm heat syndrome;and in T3(BL13),T11(BL20)segments of group of Heart-Cholecyst deficiency syndrome;but there was no significant pertinence in all segments of group of Heart-Spleen deficiency syndrome and group of Yin-Deficiency and Fire-Hyperactivity syndrome.In comparison of the pain threshold corresponding to the position of left Bac-shu points of five types of insomnia patients,there were significant differences generally lower in all segments of group of stagnation of liver fire syndrome,especially in T4(BL14),T5(BL15),T11(BL20)segments;and in T5(BL15)segment of group of phlegm heat syndrome and group of Heart-Cholecyst deficiency syndrome;and in T11(BL20)segment of group of Heart-Spleen deficiency syndrome;but there was no significant pertinence in all segments of group of Yin-Deficiency and Fire-Hyperactivity syndrome.In comparison of the pain threshold corresponding to the position of right Bac-shu points of five types of insomnia patients,there were significant differences generally lower in all segments of group of stagnation of liver fire syndrome;and in T3,T12 segments of group of phlegm heat syndrome;and in T3 segment of group of Heart-Spleen deficiency syndrome;and in T4 segment of group of Yin-Deficiency and Fire-Hyperactivity syndrome;but there was no significant pertinence in all segments of group of Heart-Cholecyst deficiency syndrome.[Conclusion]There is a specific positive reaction area in the Du meridian(spine)and Back-Shu points of primary insomnia patients and among different types of insomnia patients.The region of specific positive reaction points in patients with primary insomnia is concentrated in the T3-T5 segments of the upper back.There were frequently specific positive reactions in T8 and L4,which may reflect the correlation of qi between insomnina and digesive system.Furthermore,there were significant differences generally lower in all segments of group of stagnation of liver fire syndrome which may reflect the disorder of qi can Lead to the stiffness of the back muscles.At the same time,we also found that the specific positive reaction points in the spine than in the Back-Shu points which can better reflect the positive difference between the different types of syndromes.Therefore those specific positive reaction points can be provided more direct guidance of meridian examination at clinical diagnosis and treatment of insomnia patients.
