Abstract：Objective To investigate the effect of intermittent θ pulse stimulation(iTBS)combined with continuous passive exercise training on the rehabilitation outcomes of patients with anterior cruciate ligament(ACL)injuries after surgery.Method A total of 80 patients with ACL injuries who underwent arthroscopic ligament reconstruction surgery at the jiujiang 171 hospital,from January 2021 to July 2024 were selected.There were 60 male patients and 20 female patients,with an average age of(31.1±6.5)years old,ranging from 19 to 51 years old.According to different rehabilitation methods after surgery,they were divided into the control group(n=39)and the observation group(n=41).The control group received continuous passive movement training,while the observation group received additional iTBS intervention on the basis of the control group.Both groups were continuously intervened for 6 weeks to determine the intervention effect.The early postoperative pain degree,knee joint proprioception before and after intervention,and knee joint function of the two groups were compared.Results Both groups of patients did not experience severe pain.The proportion of patients with moderate pain in the control group was higher than that in the observation group,and the difference was statistically significant(P＜0.05).Before the intervention,there was no statistically significant difference in the 30° and 60° passive angulation errors of the affected knees between the two groups(P＞0.05);after 6 weeks of intervention,the passive angulation errors of the affected knees in both groups decreased,and the passive angulation error of the affected knee in the observation group was smaller than that in the control group,with a statistically significant difference(P＜0.05).Before the intervention,there was no statistically significant difference in the hospital for special surgery knee score(HSS)scores between the two groups(P＞0.05);after 6 weeks of intervention,the HSS scores of both groups increased compared to before the intervention,and the HSS score of the observation group was higher than that of the control group,with a statistically significant difference(P＜0.05).Conclusion The combination of iTBS and continuous passive exercise training can alleviate early postoperative pain in patients with ACL injuries,improve knee proprioception,and promote knee joint function recovery.
