Application and imaging observations of static stretching technique combined with muscle energy technique in Post-ACL reconstruction
Objective To investigate the impact of muscle energy technique(MET)combined with static stretc-hing technique(SPS)on knee joint function after anterior cruciate ligament(ACL)reconstruction.Methods Eighty patients who underwent ACL reconstruction between December 2021 and March 2023 in the Department of Rehabilitation Medicine,Hanzhong Central Hospital were randomly divided into an experimental group(n=40)and a control group(n=40).The control group received conventional rehabilitation training,including Kaltenborn joint mobilization,strength training,ultrasound therapy,and wax therapy.The experimental group received MET and SPS in addition to the conventional therapy.Knee joint function scores(FAC,IKDC,and HSS),active range of motion(AROM),pain score(VAS),self-efficacy(GSES),and kinesiophobia(TSK)were evaluated before and after treatment.Imaging assess-ments,including ultrasound and MR1,were conducted.Results Compared to pre-treatment,both groups showed sig-nificant improvement in HSS,IKDC,and FAC scores,as well as AROM.VAS scores decreased significantly(P＜0.05).The experimental group demonstrated significantly greater improvement than the control group(P＜0.05).GSES scores increased and TSK scores decreased significantly in both groups post-treatment(P＜0.05),with the experimental group showing superior outcomes compared to the control group(P＜0.05).There was no significant difference in quadri-ceps muscle blood flow(MBF)between the two groups pre-treatment(P＞0.05).Both groups exhibited a significant increase in MBF post-treatment(P＜0.05),with the experimental group showing a significantly greater increase than the control group(P＜0.05).Imaging findings from MRI indicated that SPS combined with MET is safe for reconstructed ligaments and does not cause secondary damage to the postoperative knee joint.Conclusion The combination of SPS and MET effectively alleviates knee pain,improves knee function and stability,and enhances patient compliance with rehabili-tation exercises after ACL reconstruction.These techniques are safe and effective in clinical application.
