下肢开链增重法对脑卒中患者位置觉和步态对称性的即刻影响

Immediate Effects of Lower Limb with Open Chain Weight-adding on Joint Position Sense and Gait Symmetry in Stroke Patients

目的研究下肢开链增重对脑卒中患者位置觉和步态对称性的即刻影响。方法 2016年1月至2017年1月,选取本院脑卒中患者39例,分别在增重前后进行下肢位置觉测评,包括主动定位-主动复位(ARAP)和被动定位-被动复位(PRPP)测评,记录目标角度与复位角度差值;以及步态测评,记录足偏角对称性、步长对称性、单腿支撑相时长对称性。结果下肢增重后,髋直腿抬高PRPP位置觉无改善(t=0.832,P=0.832),ARAP位置觉改善(t=3.158,P=0.011);足偏角对称性无改善(t=-0.704,P=0.483),步长对称性改善(t=2.022,P=0.041),单腿支撑相对称性无改善(t=0.381,P=0.702)。结论下肢开链增重可以改善脑卒中患者的下肢主动位置觉和步长对称性。

Objective To investigate the immediate effects of lower limb with open chain weight-adding on joint position sense and gait symmetry in stroke patients.Methods From January,2016 to January,2017,39 stroke patients were included.Their joint position sense and gait symmetry were compared before and after weight-adding.The joint position senses of active reproduction of active positioning（ARAP）and passive reproduction of passive positioning（PRPP） were assessed during lower limb straight leg raise.The gait symmetry was also assessed and three indexes were recorded including the symmetry of foot rotation angle,step length and percentage of single leg support phase.Results After weight-adding,the position sense of PRPP did not improve（t=0.832,P=0.832）,nor of the symmetry of foot rotation angle（t=-0.704,P=0.483） and percentage of single leg support phase（t=0.381,P=0.702）;the position sense of ARAP improved（t=3.158,P=0.011）,as well as the symmetry of step length（t=2.022,P=0.041）.Conclusion The lower limb with open chain weight-adding could improve the active joint position sense and symmetry of step length.
