摘　　要：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0.51m/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 80stroke 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-independence group(accuracy 91.3%).Receiver operating characteristic(ROC)curves were employed to suggest cut-off scores and to determine overall 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 0.51m/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.
