Clinical Study Of Core Stability Training In The Treatment Of Knee Osteoarthritis

Objective:To observe the effect of core stability training on pain,knee joint function,walking ability and balance function of patients with knee osteoarthritis(KOA).Methods:46 patients with knee osteoarthritis were randomly divided into experimental group(n=23)and control group(n=23).The control group was given conventional rehabilitation therapy,including quadriceps training and microwave therapy,and the experimental group was supplemented with core stability training on the basis of the control group,with an intervention cycle of 4 weeks.Patients’pain,knee joint function,and walking ability were assessed before and after treatment using a visual analogue scale(VAS),Western Ontario and Mc Master Universities Osteoarthritis Index score(WOMAC),and 6-minute walk distance,and balance parameters during bipedal stance,including the pressure center ellipse area,total track length of the pressure center(L),length of the pressure center on X-axis(L_X),and length of the pressure center on Y-axis(L_Y),were collected using a plantar pressure analysis system to assess balance function.Results:1.Before treatment,there was no significant difference in all evaluation indicators between the experimental group and control group(P>0.05).2.VAS score:After 4 weeks of treatment,the VAS scores of the two groups were significantly lower than those before treatment(P<0.05),and the scores of the experimental group were better than those of the control group(P<0.05).3.WOMAC score:After 4 weeks of treatment,WOMAC pain,stiffness,function score and total score in the two groups were significantly lower than those before treatment(P<0.05),and WOMAC pain,function score and total score in the experimental group were better than those in the control group(P<0.05),but there was no significant difference in stiffness score between the two groups(P>0.05).4.6-Minute Walk Distance:After 4 weeks of treatment,6-Minute Walk Distance in both groups was significantly higher than that before treatment(P<0.05),but there was no significant difference between the two groups(P>0.05).5.Balance function indicators:After 4 weeks of treatment,the ellipse area,L,L_X and L_Y in the experimental group were significantly lower than those before treatment(P<0.05),while all balance function indicators in the control group were not significantly changed compared with those before treatment(P>0.05),and L,L_X and L_Y in the experimental group were superior to those in the control group(P<0.05),but there was no significant difference in ellipse area between the two groups(P>0.05).Conclusions:1.Both conventional rehabilitation and core stability training combined with conventional rehabilitation can effectively relieve pain and improve knee joint function and walking ability in the treatment of KOA,but increasing core stability training is more effective in improving pain and knee joint function.2.Conventional rehabilitation has no significant effect on restoring balance function,but combined with core stability training can effectively improve balance function in patients with KOA.
