Effects of foot intrinsic muscle strengthening training on knee function after total knee arthroplasty
Objective:To explore the effects of foot intrinsic muscle strengthening training on knee function and gait in patients after total knee arthroplasty(TKA).Method:Eighty-two patients with unilateral severe knee osteoarthritis were randomly divided into treatment group(n=41)and control group(n=41).The control group received routine rehabilitation treatment after knee re-placement,while the treatment group received additional foot intrinsic muscle strengthening exercises alongside standard rehabilitation.Functional outcomes were evaluated preoperatively and at 12 weeks postoperatively us-ing the Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC).Balance function was as-sessed using the Berg Balance Scale(BBS)and the Modified Falls Efficacy Scale(MFES).Gait analysis was per-formed using portable intelligent gait analysis equipment.Result:After 12 weeks of rehabilitation,the study group showed significantly better outcomes in WOMAC scores,MFES scores and BBS than those in the control group(P<0.05).The single leg support time,step speed and step length of the operative limb in the treatment group were significantly improved compared with the control group(P<0.05).Conclusion:Twelve weeks of foot intrinsic muscle strengthening exercises post-TKA can improve physical func-tion,balance ability,and gait in patients.
