Abstract： Objective：To observe the effects of Fu's subcutaneous needling combined with conventional therapy on pain relief，shoulder range of motion（ROM），and functional recovery after manipulation under anesthesia（MUA） for frozen shoulder（FS）．Methods： A total of 58 FS patients treated with MUA at the Sports Injury Center of Higher Education Mega Center Hospital of Guangdong Provincial Hospital of Chinese Medicine from may 2023 to may 2025 were divided into the control group（n=30）and the trial group（n=28）using the random number table method．The control group received postoperative conventional therapy，while the trial group received additional Fu's subcutaneous needling treatment． Visual Analogue Scale（VAS）scores，shoulder ROM，and Constant-Murley Score（CMS）were compared between the two groups．Results：After each Fu's subcutaneous needling treatment，the pain VAS score in the trial group decreased significantly compared to pre-treatment values （P＜0.05）. Before the second and third Fu's subcutaneous needling sessions, the VAS scores showed a slight increase compared to post-treatment values from the previous session，but the overall trend during the treatment period was a decline in pain scores. On postoperative day one， there was no statistically significant difference in shoulder ROM （including forward-flexion， abductionextension， and external rotation）between the two groups（P＞0.05）. However, the trial group exhibited less internal rotation ROM than the control group（P＜0.05）. At two weeks after surgery，the trial group demonstrated significantly better ROM in forward-flexion，abduction, and external rotation compared to the control group（P＜0.05）. After each Fu's subcutaneous needling session， the trial group showed increased ROM in forward - flexion, abduction， and external rotation（except after the second session） compared to pre-treatment values, with statistically significant differences（P＜0.05）. Between the second and third sessions，ROM changes varied (some directions improved while others slightly declined）， but the overall trend was an increase in shoulder ROM during the treatment period.At two weeks after surgery， the trial group had a higher CMS than the control group （P＜0.05）. Conclusion： Fu's subcutaneous needling combined with conventional treatment provides immediate pain relief for FS patients after MUA, improves short-term ROM， and enhances shoulder function at two weeks after surgery. However， it does not significantly alleviate shoulder pain at the two-week follow-up.
