| Objective:Based on the theory of acupoint sensitization,this project analyzed the distribution pattern of body surface pain-sensitive points in patients with chronic non-specific low back pain(CNLBP).Also,to observe and compare the clinical efficacy of acupuncture body surface pain-sensitive points with conventional acupuncture in patients with CNLBP,in order to provide new ideas and exploration for the treatment of CNLBP by acupuncture.Methods:Sixty-four patients with CNLBP who met the inclusion and exclusion criteria and were admitted to the Department of Acupuncture and Rehabilitation Medicine of Min Dong Hospital in Ningde City between May 2020 and May 2021 were selected.Before treatment,the FDK20 pressure pain meter was applied to perform body surface pain-sensitive point exploration on the body surface area(below the rib edge,above the transverse gluteal line and between the mid-axillary lines on both sides)of 64 patients with CNLBP with a constant force of F=60N and approximately 0.5 kg/cm~2/s.The correlation between the distribution of body surface pain-sensitive points and acupuncture points and meridians was observed,and the distribution pattern was analyzed.At the same time,the patients were randomly divided into 32 patients in the group of acupuncture body surface pain-sensitive points(test group)and 32 patients in the group of conventional acupuncture(control group);the test group selected 5 body surface pain-sensitive points with the highest force-sensitivity value for acupuncture treatment,and the control group selected 5fixed acupuncture points——Shènshū(肾俞BL23),Dàchángshū(大肠俞BL25),Mìngmēn(命门DU4),Yāoyángguān(腰阳关DU3),and Wěizhōng(委中穴BL40)for acupuncture treatment;both groups were treated once a day from Monday to Friday for 2weeks a total of 10 times;the changes in visual analogue scale(VAS),Oswestry disability index(ODI)and lumbar joint mobility of before treatment,after 5 treatments and after 10treatments were observed in the two groups to compare the clinical efficacy.Results:1.A total of 320 body surface pain-sensitive points were collected from 64 patients with CNLBP before treatment,of which 312(97.5%)were distributed around acupuncture points(distance between body surface pain-sensitive points and the nearest acupuncture point≤1.3 inch)and 8(2.5%)were distributed in non-acupuncture point areas;16sensitized acupuncture points were involved,with an average sensitization range of(0.40±0.33)inch,of which the number of pain-sensitive points around Qìh?ishū(气海俞BL24)was the largest(accounting for 17.95%),followed by Large——Dàchángshū(大肠俞BL25),Huántiào(环跳穴GB30),Zhìbiān(秩边穴BL54),Guānyuānshū(关元俞BL26),Yāoshū(腰俞DU2),Shènshū(肾俞BL23),and Yāoyángguān(腰阳关DU3)(a total of65.37%);3 sensitized meridians were involved,in order:the Foot Solar Bladder Meridian(70%),the Governor Meridian(17.5%),and the Foot Shaoyang Gallbladder Meridian(10%).2.The VAS scores were significantly lower in both groups before and after treatment(P<0.001);and the VAS scores of patients in the test group were significantly lower than those in the control group after treatment,with statistically significant differences(P<0.001).3.The ODI index was significantly lower in both groups before and after treatment(P<0.001);and the ODI index of patients in the test group was significantly lower than that of the control group after treatment,and the difference was statistically significant(P=0.005).4.The lumbar joint mobility was significantly improved in both groups before and after treatment(P<0.001);and the posterior extension,left flexion,right flexion,left rotation and right rotation angles of the patients in the test group were significantly greater than those in the control group after treatment,with statistically significant differences(P<0.05),and only anterior flexion was not statistically significant between the two groups(P=0.536).Conclusion:1.The body surface pain-sensitive points of CNLBP patients are closely related to the common acupoints of acupuncture for low back pain——Dàchángshū(大肠俞BL25),Huántiào(环跳穴GB30),Zhìbiān(秩边穴BL54),Guānyuānshū(关元俞BL26),Yāoshū(腰俞DU2),Shènshū(肾俞BL23),and Yāoyángguān(腰阳关DU3);and closely related to the common meridians of acupuncture for low back pain——Taiyang Bladder Channel of Foot,Governor vessel,Shaoyang Gallbladder Meridian of Foot.2.Both acupuncture at the body surface pain-sensitive point and conventional acupuncture relieved pain and improved lumbar spine function and lumbar spine joint mobility in patients with CNLBP;and the efficacy of acupuncture at the body surface pain-sensitive point was better than that of conventional acupuncture. |
