概括
患有脑 (CP) 的儿童表现出曲的膝盖步态,这并不总是由于膝盖收缩. 这种步态会影响功能性移动,特别是在更严重的病例中 (GMFCS II-III级).
科学领域:
- 生物医学工程 生物医学工程
- 儿科整形外科 儿科整形外科
- 神经学 神经学
背景情况:
- 屈曲的膝盖步态是患有脑 (CP) 的儿童的常见特征.
- 这种步行模式通常与膝关节缩有关,影响了运动能力.
研究的目的:
- 为了比较 CP 儿童在行走时的膝盖位置与被动膝盖延伸.
- 通过不同级别的毛发动机功能分类系统 (GMFCS) 来调查患有CP的儿童曲膝盖步态和功能移动性之间的关系.
主要方法:
- 3D运动分析用于评估30名双边性脑脊髓炎 (GMFCS I-III级) 的儿童和22名典型发育 (TD) 的儿童的步态.
- 测量了最初接触时的膝盖角 (KneeAngleIC) 和姿势中的膝盖最小屈曲 (MinKneeFlexSt).
- 功能性移动性是使用定时起飞和起飞测试来评估的.
主要成果:
- 在所有组中,KneeAngleIC都大于MinKneeFlexSt.
- 在GMFCS II和III级别,MinKneeFlexSt超过了测量的膝盖收缩.
- 与GMFCS I和TD组相比,GMFCS II和III级的KneeAngleIC和MinKneeFlexSt都显著增加.与GMFCS I和TD组相比,GMFCS II和III级的KneeAngleIC和MinKneeFlexSt都显著增加.
- 在GMFCS II和III中,膝盖过度曲并不能完全由膝盖收缩解释.
- 定时启动测试结果表明GMFCS III级的持续时间较长,与耗能的步态和空间不安全有关.
结论:
- 患有CP的儿童的膝盖曲步行,特别是更高的GMFCS水平,可能不仅仅归因于膝盖收缩.
- 观察到的步态模式可能导致功能移动性减少和能源消耗增加.
- 区分被动膝盖延伸和承重膝盖延伸对于理解CP曲膝盖步行的潜在原因至关重要.

01:23Knee Joint
1.8K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

01:23Muscles that Move the Leg
1.8K
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...

01:16Bones of the Lower Limb: Femur and Patella
2.5K
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...

01:22Somatic Spinal Reflexes
2.1K
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...
