概括

这项研究发现,中风后四头骨到足底的异名反射没有显著差异. 然而,肢刺激增加可能与更快的步行速度相关,这表明它可能在运动恢复中发挥作用.

科学领域:

神经科学是一个神经科学.
发动机控制器的控制器
康复科学康复科学康复科学

背景情况:

变化的四头骨 (Q) 到单头骨 (SOL) 异名反射可能会导致中风后异常的联合激活.
关于中风后个体是否表现出改变的反射以及增加兴奋的起源 (兴奋与抑制) 缺乏共识.

研究的目的:

为了研究异名激发和抑制从Q到SOL在paretic,nonparetic和控制四肢.
为了确定是否增加刺激源于刺激或减少抑制电路.
探索反射幅度与恢复和功能的临床测量之间的相关性.

主要方法:

在中风后的14个人和14个对照中检查了异名激发和从Q到SOL的抑制.
在增强性SOL激活期间刺激大腿神经和Q肌 (20%最大).
在中风幸存者中评估了Fugl-Meyer,10米步行测试和Mini-BESTest.

主要成果:

在性,非性或对照肢体之间没有发现异名激发/抑制发作,持续时间或大小的显著差异.
Q肌肉刺激产生的激发大小是股骨神经刺激的一半.
股骨神经引起的肢刺激与步行速度 (n=8,r=0.69,P=0.058) 呈现出正相关性,尽管在统计学上不显著.

结论:

坐着姿势中的异名Q-to-SOL反在中风后没有受到损害.
四头肌刺激可以在过度兴奋的情况下更好地评估异名抑制.
在较高的正常范围内,肢激发可能会促进中风后的行走,这需要在直立姿势和运动任务中进行进一步的研究.

Muscles of the Leg that Move the Foot and Toes

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....

Pulse Assessment Sites

Pulse Assessment Sites

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
