概括

下肢肌肉疲软,特别是最弱的肢体,是多发性硬化症 (PwMS) 患者中脱落者与非脱落者的关键指标. 经常发生的崩显示出广泛的弱点,突出了针对性强度干预的需要.

科学领域:

  • 神经学 神经学
  • 康复科学 康复科学 康复科学
  • 运动科学 运动科学

背景情况:

  • 对于患有多发性硬化症 (PwMS) 的人来说,跌倒是一个重大问题,影响了他们的移动性和生活质量.
  • 了解导致摔倒的生物力学因素对于制定有效的预防策略至关重要.

研究的目的:

  • 调查特定下肢 (LL) 肌肉群的最大自愿收缩 (MVC) 是否可以区分有或没有跌倒史的PwMS.
  • 根据下降频率 (偶尔与反复) 分析LL强度的差异.

主要方法:

  • 一项涉及172名PwMS的横截面研究的二次分析.
  • 用Biodex动力计测量下肢MVC的部曲,延伸,绑架,膝盖曲/延伸以及脚脚下曲/后背曲.
  • 参与者被分为非跌倒者 (0次跌倒) 和跌倒者 (≥1次跌倒),而跌倒者进一步被分为偶尔 (1-2次跌倒) 和反复 (≥3次跌倒).

主要成果:

  • 与未跌倒者相比,有跌倒史的PwMS在最弱四肢 (LL-W) 的所有测量LL肌群和最强四肢 (LL-S) 的几个肌群中表现出明显较低的强度.
  • 在所有LL-W和关键LL-S群体 (部延伸,曲,绑架,脚脚下曲) 中,反复发生的暴跌显示出力量减弱.
  • 偶尔的落显示部绑架,膝盖曲/最弱肢体延伸的强度降低,并且与最弱肢体部延伸的反复落不同.

结论:

  • 下肢肌肉疲弱,特别是最弱的肢体,是PwMS中患病者和非患病者之间的显著差异化因素.
  • 跌倒的频率会影响肌肉衰弱的模式和程度,反复跌倒的人会表现出更明显的缺陷.
  • 这些发现强调了评估和解决PwMS中LL强度缺陷的重要性,以告知临床护理和跌倒预防策略.
