Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

1.3K
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....

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.2K
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...

科学领域:

  • 生理学 生理学 生理学
  • 生物力学 生物力学
  • 运动科学 运动科学

背景情况:

  • 脚 flexors对于运动和平衡至关重要.
  • 之前的研究表明,单脚不使用会影响脚下 flexor 的强度和大小.
  • 没有任何元分析能够量化这些对未受伤的成年人的影响.

研究的目的:

  • 量化评估足部屈曲器强度的变化.
  • 量化评估足部 flexor 大小的变化.
  • 为了分析单腿不使用在未受伤的成年人的影响.

主要方法:

  • 对19项使用单边下肢固定 (造/支架) 的研究进行了元分析.
  • 包括到2022年1月30日发表的研究.
  • 分析了最初的研究报告,报告了脚部 flexor 的强度和尺寸.

主要成果:

  • 单脚不使用下降了脚下 flexor 的强度 (Hedges g = -0.71).
  • 脚部曲器的大小也减少了 (Hedges g = -0.33).
  • 在不同停用时间 (7-35天) 中观察到的效果.

结论:

  • 单脚不使用导致脚下 flexor 的强度和大小显著减少.
  • 这些发现与对膝盖延伸器下降的元分析一致.
  • 未来的研究应该包括更多的女性和老年人.
