概括
脑中风后,从四头肌到肌底肌肉的异名反不会受到损害. 然而,肢刺激的增加可能与更快的步行速度相关.
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
- 康复科学科学 康复科学
背景情况:
- 从四头骨到足骨的异名反变化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异名反射及其潜在机制 (增加刺激和/或减少抑制) 缺乏共识.
研究的目的:
- 为了检查异名激发和抑制从四头四肢到单体在paretic,nonparetic,和控制四肢.
- 为了确定刺激的增加是由于刺激性或抑制性反射回路的减少.
- 调查异名反射幅度与下肢恢复和行走能力的临床测量之间的关系.
主要方法:
- 在14名中风后患者和14名年龄相匹配的对照人群中,研究了从四头骨到足骨的异名激发和抑制.
- 通过大腿神经和四头肌肌肉刺激在索莱乌斯增强激活过程中引起异名反.
- 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,非性和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.
- 与大腿神经刺激相比,四头肌刺激的激发幅度只有半个.
- 股骨神经引起的肢激发显示出与参与者的子集的步行速度的正相关性.
结论:
- 从四头骨到足部的异名反,在坐姿中评估,似乎在中风后没有受损.
- 四头肌刺激可以在过度兴奋的个体中更好地估计异名抑制.
- 在正常范围内,肢异名激发可能会对中风后的步行速度产生积极影响.

Muscles of the Leg that Move the Foot and Toes
1.1K
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....

Muscle Stimulation Frequency
2.0K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...

Pulse Assessment Sites
886
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...

Bones of the Lower Limb: Femur and Patella
2.1K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Muscles that Move the Leg
1.3K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...
