Methods: In this study, 120 patients with periarthritis of shoulder who were admitted to the department of orthopedics of the second affiliated hospital of Heilongjiang university of traditional Chinese medicine from June 2018 to June 2019 were selected, and the patients were divided into warm acupuncture group, massage group, combined treatment group and control group with a random number table, with 30 patients in each group. Warm acupuncture and moxibustion group received 4 weeks of warm acupuncture and moxibustion treatment, massage group received 4 weeks of massage treatment, patients in the combined treatment group received 4 weeks of warm acupuncture and moxibustion treatment, patients in the control group received 4 weeks of ultrashort wave combined plaster treatment. The use of ibuprofen, VAS score, Melle score, TCM syndrome score and serum inflammatory factors before and after treatment were analyzed and compared in each group of patients to evaluate the clinical efficacy. Results:shoulder joint pain and activity limitation were significantly improved in each group, VAS score, Melle score, TCM syndrome score and serum inflammatory factor levels were significantly decreased compared with before treatment (P < 0.05), and the improvement in the combined treatment group was significantly better than that in other groups (P < 0.05). Conclusion: Warm acupuncture combined with manipulation can significantly improve the clinical symptoms of periarthritis of shoulder, improve the mobility of shoulder joint, and inhibit the internal inflammatory response, which is significantly better than using warm acupuncture or manipulation alone and conventional physical therapy.展开更多
