Medicine and science in sports and exercise
|July 1, 2025
概括
急性侧脚扭伤 (ALAS) 增加皮质脊髓刺激能力,而不是脊髓反射刺激能力. 这种神经变化与较大的脚残疾有关,强调了中枢神经系统适应在恢复中的作用.
科学领域:
- 神经科学是一个神经科学.
- 运动医学 运动医学
- 整形外科 整形外科 整形外科
背景情况:
- 急性侧脚扭伤 (ALAS) 可以改变神经刺激能力,可能导致感觉运动功能障碍.
- 了解脊柱和脊柱上机制对于评估ALAS相关缺陷至关重要.
研究的目的:
- 调查ALAS在单脚姿势期间对神经刺激性的影响.
- 为了将这些神经适应与临床结果相关联.
主要方法:
- 通过霍夫曼反射 (H-反射) 评估脊柱反射刺激能力和使用运动唤起潜能 (MEP) 的皮质脊柱刺激能力.
- 测量单脚压力中心 (CoP) 用于姿势控制和评估急性症状和脚残疾.
主要成果:
- 在ALAS和对照组之间,脊柱反射兴奋度没有显著差异.
- 在所有刺激强度的ALAS组中观察到显著更高的皮质脊髓刺激能力.
- ALAS 组表现出 postural 控制受损 (增加 CoP 面积和速度),以及较高的皮质脊髓刺激性和较大的脚残疾之间的相关性.
结论:
- 亚拉斯主要影响在单脚姿势期间在皮质脊髓层面的神经刺激性.
- 皮质脊髓变化可能导致ALAS后体验到的感觉运动缺陷和残疾.

Somatic Spinal Reflexes
2.7K
Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Reflex Activity
2.0K
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.

Muscles of the Leg that Move the Foot and Toes
2.3K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
