目的：探讨Berg平衡量表（Berg balance scale ，BBS）和步行速度（walking speed ，WS）对脑卒中患者病区步行自立度的判定价值。方法对80例脑卒中的BBS和WS进行测量和分析。结果 BBS和WS对病区步行自立度具有良好的判别效力，预测病区步行自立度正确率为91.3％；ROC曲线分析提示判断病区步行自立度的最佳BBS临界值为46.5分，敏感性5％，特异性为77.8％，ROC曲线下面积为0.900；判断病区步行自立度的最佳WS临界值为0.51 m/s ，其相应的敏感性为86.8％，特异性为88.9％，ROC 曲线下面积为0.956。结论 BBS和WS可以较好的判别脑卒中患者的病区步行自立度。

Objective To study the value of the Berg Balance Scale(BBS)and the walking speed(WS)for the identification about the ward walking independency in the stroke patients .Methods The BBS and the 10-m WS of 80 stroke patients were measured and analyzed . Results Using discriminate analysis ,the BBS and the 10m WS were found to be the good discriminators of independency and non-independ-ence group(accuracy 91.3% ) .Receiver operating characteristic(ROC)curves were employed to suggest cut-off scores and to determine over-all predictability ,for BBS :cut-off point 46.5 ,sensitivity 92.5% ,specificity 77.8% and area under ROC curve 0.900 ;and for WS :cut-off point 0.51 m/s ,sensitivity 86.8% ,specificity 88.9% % ,and area under ROC curve 0.956.Conclusion This study suggests that the BBS and the WS were a good measure for discriminating ward walking independency in the stroke patients .
