摘要:

目的 观察股四头肌痉挛对脑卒中患者跨越障碍的影响。

方法 2017年10月至2018年11月,招募脑卒中患者20例,根据股四头肌改良Ashworth量表(MAS)分级分为痉挛组(n = 11)和无痉挛组(n = 9)。采用三维运动捕捉系统和测力台同步采集患者跨越高15 cm障碍时的步长、步宽、前后和内外质心速度、健侧足尖-障碍物距离、患侧足尖-障碍物垂直间距、障碍后足跟-障碍物距离、双支撑和健患侧摆动期百分比等。

结果 在患侧和健侧脚尖位于障碍正上方时,痉挛组前后方向质心速度均明显小于无痉挛组(F > 10.006, P < 0.01);痉挛组足尖-障碍物距离和障碍前步长均明显小于无痉挛组(F > 13.456, P < 0.01);痉挛组障碍前双支撑百分比和障碍后步宽大于无痉挛组(F > 4.533, P < 0.05)。

结论 股四头肌痉挛导致脑卒中患者跨越障碍时持更谨慎的策略,效率降低。

Abstract:

Objective To observe the effect of quadriceps femoris spasticity on the movement parameters in stroke patients during obstacle crossing.

Methods From October, 2017 to November, 2018, 20 stroke patients were divided into spasticity group (n = 11) and non-spasticity group (n = 9) based on the score of modified Ashworth Scale (MAS) of quadriceps femoris. A 10-camera 3D motion analysis system and two force plates were used to synchronously measure the movement parameters of the patients during obstacle crossing of 15 cm high, such as step length, step width, anterior-posterior velocity of the center of mass (COMAPV) and medio-lateral velocity of the center of mass, toe-obstacle distance of unaffected limb, toe-obstacle clearance of affected limb, heel-obstacle distance, double support phase, and the swing phases of affected and unaffected limb.

Results Compared with the non-spasticity group, the COMAPV decreased as both affected and unaffected limb above the obstacle in the spasticity group (F > 10.006, P < 0.01), as well as the toe-obstacle distance and step length before obstacle crossing (F > 13.456, P < 0.01); while, the double support phase and the step width after obstacle crossing increased (F > 4.533, P < 0.05).

Conclusion The quadriceps femoris spasticity may make the strategy of obstacle crossing more carefully for stroke patients, and less efficiently.
