概括

患有慢性脚不稳定症 (CAI) 的人在行走过程中会在未受影响的肢体上表现出改变的皮肤反射. 这些发现表明,侧脚扭伤 (LAS) 后的全身神经变化需要更广泛的康复方法.

科学领域:

神经科学是一个神经科学.
生物力学生物力学
运动医学运动医学

背景情况:

慢性脚不稳定 (CAI) 是脚损伤的常见后果,表现为超出受伤四肢的感觉运动缺陷.
在CAI患者中观察到皮肤反射变化,特别是在外围神经刺激后.
之前的研究还没有研究单边CAI患者的未受影响四肢的皮肤反射.

研究的目的:

测量和比较单边CAI和健康对照对象在步行时的逆侧皮肤反射.
为了调查侧脚扭伤 (LAS) 后潜在的系统神经变化.

主要方法:

19名参与者 (单边CAI和健康对照) 接受了6个下肢肌肉的肌肉活动测量.
随机的,无害的外围神经刺激在行走任务中被应用.

主要成果:

在CAI组中,皮肤反射模式与步行周期中的对照不同.
具体的变化包括在CAI组中缺乏侧面胃角膜促进和中间胃角膜抑制.
在CAI组中,在逆侧摆动期间,双腿肌 (BF) 的促进减少也被注意到.

结论:

单边CAI患者的反射变化延伸到未受影响的四肢,表明LAS后的脊柱水平变化.
观察到的反射变异可能归因于增加的运动输出变异性.
对于LAS的康复应该考虑全身神经通路,而不仅仅是局部缺陷.

关键词:

Reflex Activity

Reflex Activity

A reflex activity is an automatic, involuntary response to specific stimuli. It is a part of our survival mechanism, designed to protect us from potential harm. For example, when a bright light suddenly shines into our eyes, we instinctively close them or look away. This is a simple reflex activity orchestrated by the nervous system without conscious thought or effort.
A reflex exam is a diagnostic procedure performed by a healthcare professional to evaluate the functionality of a patient's...

Indirect Motor Pathways

Indirect Motor Pathways

The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...
