悬吊训练在膝关节置换术后康复中的作用

Effect of Sling Exercise Therapy on Rehabilitation after Total Knee Arthroplasty

目的观察悬吊训练在膝关节置换术后康复中的作用。方法 46例膝关节置换术后患者,随机分为悬吊训练（SET）组（n=23）和持续被动运动训练（CPM）组（n=23）。CPM组给予持续被动运动训练,SET组给予悬吊训练。术前、术后15 d、术后3个月采用膝关节活动度（ROM）、膝关节功能量表（HSS）和姿势控制能力进行评估。结果术后15 d,SET组患者的膝关节最大被动屈曲角度比CPM组增加6.0°（95%CI=0.9°~11.2°;P〈0.01）,膝关节最大主动屈曲角度比CPM组增加5.7°（95%CI=0.4°~9.1°;P〈0.01）;但两组最大主动伸展角度、最大被动伸展角度、HSS评分（除活动度外）、姿势控制能力均无显著性差异（P〉0.05）。术后3个月,两组间所有评估项目均无显著性差异（P〉0.05）。结论 SET在短期内增加膝关节ROM比CPM更有效,可以用于膝关节置换术后的早期康复。

Objective To observe the effect of sling exercise therapy（SET） on rehabilitation after knee arthroplasty.Methods 46 patients after knee arthroplasty were randomly divided into experimental group（n=23） and control group（n=23）.The control group received continuous passive motion（CPM） training,while the experimental group received SET.They were evaluated with range of motion（ROM）of the knee,Hospital for Special Surgery Knee Score（HSS） and posture control ability before,15 days and 3 months after operation.Results 15 days after operation,the maximal passive knee flexion was 6.0° more in the SET group than in the CMP group（95%CI=0.9°~11.2°;P〈0.01）,and the maximal active knee flexion was 5.7° more in the SET group than in the CMP group（95%CI=0.4°~9.1°; P〈0.01）; however,there was no significant difference in the maximal active knee extension,the maximal passive knee extension,HSS and posture control ability between 2 groups（P〉0.05）.3 months after operation,there was no significant difference in all the items between 2 groups（P〉0.05）.Conclusion Compared with CPM,SET might be more effective on increasing knee ROM in the short-term,and could be used as an effective intervention for patients after knee arthroplasty at the early stage.
