The Study On Clinical Efficacy Of Inner Heating Dry Needles Treating Nonspecific Low Back Pain

Objective The patients who have the nonspecific low back pain were treated by the dry needles of inner heating and thermal magnetic therapy. To explore the clinical efficacy under the dry needles of inner heating on low back pain through the VAS score, JOA score, infrared temperature, muscle tension, microcirculation and other indicators. Provide clinical trials support to the dry needles of inner heating in clinical evaluation and clinical application therapy.Methods 1) 40 cases of patients were treated by dry needle of inner heating, 20 cases of patients were treated by thermal magnetic,another 19 healthy people were enrolled as control group. The treatment group of patients with chronic low back pain duration ?6 months.2) Inner heating dry needle group:treat the patients in twice under points on lower lumbar(L4-S1) and lumbosacral(S1- S3), each time positioning the needle point 10, using 1.1mm × 100 mm disposable dry needle of inner heating. After disinfection, local anesthesia, conventional piercing. After the completion of all of the needle, heating time 20 min. Thermomagnetic treatment groups: thermal magnetic device on the lower back area for treatment, treatment temperature 40 ?, treatment time 20 min, 6 times a week for two weeks.3) Observe the VAS score, JOA score, infrared temperature, muscle tension, microcirculation and other indicators during before treatment and after 14 days of treatment. After 2-months treatment, patients were followed up again for VAS and JOA scores.4) Applications SPSS17.0 statistical software for data analysis, measurement data was used mean±standard deviation, count data to form than described. P<0.05 was considered statistically significant. Before and after treatment VAS, JOA, infrared temperature, muscle tension compared with paired T-test, comparison between groups using independent sample T-test. Microcirculation abnormal rate was used to compare test for statistical analysis. VAS, JOA and muscle tension correlation analysis using Spearman rank correlation test.Results 1) VAS score changes, after 14 days and 2-months treatment by dry needle the VAS scores lower than the patients before treatment by dry needle of inner heating(P<0.01), and VAS scores after prolonged treatment was reduced(P<0.01).2) JOA score changes, after 14 days and 2-months treatment by dry needle the JOA scores higher than the patients before treatment by dry needle of inner heating(P<0.01), and JOA scores after prolonged treatment was raised(P<0.01).3) Low back temperature of the treatment group in before-treatment was higher than control group(P<0.05); Low back temperature of the dry needle group in after-treatment was lower than before(P<0.05); while no remarkable differences were found between the after-treatment dry needle group and control group(P >0.05).4) Changes in muscle tone, muscle tone of the treatment group in before-treatment was higher than control group(P<0.01); muscle tone of the dry needle group in after-treatment was lower than before(P<0.01); while no remarkable differences were found between the after-treatment dry needle group of and control group(P >0.05).5) Microcirculation, by dry needle of inner heating microcirculation abnormal rate before-treatment is lower than before-treatment(P<0.05).6) VAS, JOA was positively correlated with muscle tension in dry needle group(P<0.05).Conclusion The treatment of dry needles of inner heating can improve lumbar function in NLBP patients, relieve their pain. The treatment of dry needle of inner heating can reduce the high muscle tension of paraspinal muscle,make the emperature became normal, and adjust the microcirculation in the chronic soft tissue lesion.
