摘　　要：目的:通过对脑卒中患者躯体运动的三维运动学分析,定量分析偏瘫步态躯体运动的三维运动学特征,确定客观反映脑卒中后偏瘫步态运动学特征的量化指标。方法:选择首次脑卒中后可以独立步行10m以上的慢性单侧偏瘫患者30例为实验组,正常对照组选择具有正常步行能力的健康老人20例。采用三维步态分析系统进行运动学参数检测与分析。结果:实验组与正常对照组运动学参数比较显示,脑卒中患者骨盆前后倾斜度和骨盆旋转度、身体重心侧方运动和垂直运动范围与正常人群比较差异均有显著性意义(P<0.01)。结论:脑卒中偏瘫步态躯体运动的运动学特征:①身体重心大范围的侧方运动和小范围的垂直运动;②骨盆大范围的前后倾斜运动和旋转运动。Objective：To explore the quantitative analysis on the three-dimensional kinematics feature of the hemiplegic gait and determine the quantized standard of kinematics parameter in stroke patients with a three-dimensional motion analysis system. Method：Thirty patients with chronic hemiplegia were enrolled in experimental group who could walk at least 10m independently without a walking aid after first stroke. The control group comprised 20 non-disabled old people. Gait parameters were measured by using 3-D gait analysis system. Result： The gait analysis showed the patients in experimental group during walking increased pelvic rotation and tilt significantly （P〈0.01） in comparison with that in control group. There were no significant difference in the pelvic obliquity during hemiplegic gait walking in comparison with that in healthy elderly subjects （P〉0.05）. In experimental group during walking significantly increased lateral movements, and decreased vertical movements of the center of mass（CoM） in comparison with control group.Conclusion： The characteristics of trunk motion in stroke patients were larger lateral and less vertical movements of CoM, and larger rotative and tilted movements of pelvic.
