科学领域:

  • 神经科学是一个神经科学.
  • 康复科学 康复科学 康复科学
  • 临床神经学 临床神经学

背景情况:

  • 多发性硬化症 (MS) 经常导致身体和认知缺陷.
  • 双任务行走 (在行走时执行认知任务) 可以揭示认知运动干扰 (CMI) 和改变步态.
  • 在MS中认知障碍严重程度和CMI之间的关系尚不清楚.

研究的目的:

  • 研究MS患者的认知功能水平和CMI程度之间的关联 (PwMS).
  • 为了确定认知状态如何影响双重任务行走期间的步态调整.

主要方法:

  • 95名PwMS完成了单任务和双任务步行试验,以他们喜欢的速度进行.
  • 双重任务成本 (DTC) 从步态参数计算,以量化CMI.
  • 使用匹配测试评估认知功能;根据z分数,参与者被分为较低 (LCF) 或较高 (HCF) 的认知功能.

主要成果:

  • 与HCF组相比,LCF组在步伐速度方面表现出明显更高的DTC.
  • 在匹配测试中,脚步速度DTC和认知表现之间观察到负相关性.

结论:

  • 这项研究支持这样的假设,即行走期间的CMI与PwMS的认知功能水平有关.
  • 认知障碍直接影响MS患者管理双重任务的能力.
