BACKGROUND:Most balance disorders after total hip arthroplasty require a variety of rehabilitation methods to improve.Body weight support Tai Chi footwork can be used as a safe and effective balance training method. OBJECTIVE:To observe the effect of body weight support Tai Chi footwork on the balance function of patients after total hip arthroplasty. METHODS:Totally 74 subjects undergoing total hip arthroplasty were recruited and randomly divided into a control group(n=37)and a trial group(n=37).The control group received 30 minutes of body weight support walking training and 60 minutes of routine rehabilitation training;the trial group received 30 minutes of body weight support Tai Chi footwork training and 60 minutes of routine rehabilitation training,once a day,5 times a week,for 12 consecutive weeks.Before the intervention,4,8,and 12 weeks after intervention,the Berg balance scale and the dynamic balance ability test were used to evaluate the balance function.Harris score was used to evaluate the hip joint function,and the fall risk index was used to evaluate the fall risk. RESULTS AND CONCLUSION:(1)The four observation indicators all showed significant time effects(P<0.001).(2)Berg balance scale,Harris score and fall risk index all had an interaction effect(P<0.001),and there was a significant inter-group difference after 12 weeks of intervention(P<0.001),and the effect of the trial group was better than that of the control group.(3)After 12 weeks of intervention,there was an interaction and group effect in the scores of the front and left directions of the dynamic balance test(P<0.001),and there were significant group differences in the scores of the overall,front,left and right directions(P<0.001).(4)The results showed that after 12 weeks of intervention,the balance functions of the trial group and the control group were improved,and the improvement effect of body weight support Tai Chi footwork training was better than body weight support walking training on patients after total hip arthroplasty.
