      摘要 目的：应用步态分析，观察核心稳定性训练对脑卒中偏瘫患者步态时空参数和对称性参数的影响。 方法：选取脑卒中偏瘫患者60例，按随机数字表法将其分为观察组及对照组，每组30例。两组均进行常规治疗，观察组在此基础上给予核心稳定性训练。分别于治疗前和治疗6周后使用三维步态分析仪器检测并获得两组患者的步态参数。 结果：治疗6周后，两组患者步频、步幅、步速、患侧摆动相和健侧摆动相均较治疗前明显提高（P<0.01），步宽、步态周期、双支撑相、患侧支撑相、健侧支撑相、步长偏差、健侧患侧支撑相比值和患侧健侧摆动相比值均较治疗前显著减小（P<0.01）。组间比较显示，观察组患者的步频、步幅、步速、步宽、步态周期、双支撑相、健侧支撑相、健侧摆动相、步长偏差、健侧患侧支撑相比值和患侧健侧摆动相比值改善均明显优于对照组（P<0.05或0.01）。 结论：核心稳定性训练能有效改善脑卒中偏瘫患者步态时空参数和对称性参数，提高脑卒中偏瘫患者的步行功能和步态的对称性。

Abstract:

      Abstract Objective: To observe the effects of core stability training on temporal-spatial and symmetry parameters of gait of patients with hemiplegia after stroke through gait analysis. Method: Sixty patients with hemiplegia after stroke were randomly divided into observation group and control group with 30 cases in each group. All patients were treated with regular rehabilitation training. The observation group received core stability training in addition. Gait parameters were collected and calculated by gait analysis system at the beginning and the end of the 6th week of treatment respectively. Result: Cadence, stride length, walking velocity, paretic swing phase and nonparetic leg swing phase increased significantly compared with pre-treatment in both groups at the end of 6th week of treatment (P<0.01); Stride width, gait cycle, double limb support phase, paretic stance phase, nonparetic stance phase, step length difference, the ratio of nonparetic stance phase to paretic stance phase and the ratio of paretic swing phase to nonparetic leg swing phase decreased significantly compared with pre-treatment in both groups at the end of the 6th week of treatment(P<0.01). The parameters improved more significantly in observation group than those in control group at the end of the 6th week of treatment, including cadence, stride length, walking velocity, stride width, gait cycle, double limb support phase, nonparetic stance phase, nonparetic leg swing phase, step difference, the ratio of nonparetic stance phase to paretic stance phase and the ratio of paretic swing phase to nonparetic leg swing phase(P<0.05 or 0.01). Conclusion: Core stability training can improve the temporal-spatial and symmetry parameters of gait of patients with hemiplegia after stroke. So core stability training can improve gait function and gait symmetry.
