Objective:To analyze the level changes of the degree of back pain by visual analogue scale(VAS),lumbar function(Japanese Orthopaedic Association Scores,JOA),muscle temperature,serum serotonin 5-hydroxytryptamine(5-HT)...Objective:To analyze the level changes of the degree of back pain by visual analogue scale(VAS),lumbar function(Japanese Orthopaedic Association Scores,JOA),muscle temperature,serum serotonin 5-hydroxytryptamine(5-HT)andβ-endorphin(β-EP)in patients of low back pain(LBP).Methods:64 LBP patients treated in the tuina department of first affiliated hospital of Hainan Medical University were randomly divided into observation group(32 cases)and control group(32 cases).The control group was treated with traditional filiform acupuncture needling,the observation group was treated with Chinese tuina.VAS,JOA,muscle temperature,5-HT,β-EP,these indexes were tested before and after treatment.Results:The VAS and JOA score in the observation group were significantly lower than those in the control group(P<0.01),the muscle temperature in the observation group and the control group increased significantly(P<0.01),and the observation group was higher than that in the control group(P<0.05);5-HT、β-EP was significant difference before and after treatment(P<0.01),and the level in observation group was significantly higher than that in the control group,the difference was statistically significant(P<0.05).Conclusion:Chinese tuina has significant clinical efficacy in the treatment of LBP.The medical infrared thermal imaging technology and serum pain detection technology is conducive to objectively helpful to analyze the exact efficacy of tuina in the treatment of LBP and its impact on relevant indexes.展开更多
