摘　　要：探讨脑卒中患者步行时不同足底压力中心(COP)时空参数对称性比的适宜计算方式。选取33例脑卒中患者进行步态测试,使用3种方法计算COP时空参数的对称性比,并分析对称性比与步速的相关性。计算方式影响对称性比与步速的相关性,为了更加客观地反映步速与不对称性的相关性,对于单、双支撑期COP时空参数,可分别选用患侧除以健侧相应参数、两者中的较小值除以较大值计算对称性比,必要时根据散点图选择适宜计算方式或进行亚组分析。To explore the best calculation method of the symmetry ratio of center of pressure（COP） during gait among hemiplegie stroke survivors. Thirty-three hemiplegic stroke survivors were selected for gait analysis. Three different calculation methods were used for the symmetry ratios of COP related parameters. The correlations between velocity and symmetry ratios were analyzed. The calculation methods influenced the correlations between velocity and symmetry ratios. In order to reflect the correlation between velocity and asymmetry more objectively, for the parameters during single support phase, the paretic gait parameters could be used as numerator, and during double support phase ,the greater value as numerator. When necessary, the best method can be decided according to scatter diagram, or subgroup analysis can be done.
