Abstract： Objective： To observe the clinical efficacy of acupotomy combined with Mulligan dynamic joint mobilization in treating frozen stage scapulohumeral periarthritis． Methods： Sixty patients with scapulohumeral periarthritis treated at Department of Acupotomy in Guangming Chinese Medicine Hospital of Pudong New Area， Shanghai from January 2023 to June 2024 were divided into the treatment group and the control group using the random number table method， with 30 cases in each group． The treatment group received acupotomy and Mulligan dynamic joint mobilization， while the control group received medium-frequency pulse therapy and Mulligan dynamic joint mobilization． Both groups were treated for three weeks． Constant-Murley Score（CMS）， Visual Analogue Scale （VAS） score for shoulder pain， and shoulder range of motion（ROM） were compared between the two groups． Results： Before treatment， there was no significant difference in CMS scores between the two groups（P＞0.05）； after treatment and one month of follow-up，the CMS scores in the treatment group were higher than those in the control group，differences being significant（P＜0.05）．Before treatment，there was no significant difference in VAS scores of the shoulder joint between the two groups（P＞0.05）；after treatment and one month of follow-up，the VAS scores of the shoulder joint in the treatment group were lower than those in the control group，the difference being significant（P＜ 0.05）．Before treatment，there was no significant differences in the ROM levels of shoulder joint flexion，abduction， dorsiflexion，and arm internal and external rotation between the two groups（P＞0.05）．After treatment and one month of follow-up， the ROM levels of shoulder flexion， abduction， dorsiflexion， and arm internal and external rotation activities in the treatment group were higher than those in the control group（P＜0.05）． Conclusion： Acupotomy combined with Mulligan dynamic joint mobilization significantly relieves pain and improves shoulder function and ROM in frozen stage scapulohumeral periarthritis， with superior outcomes compared to medium-frequency pulse therapy combined with Mulligan dynamic joint mobilization.
