概括
四肢强度不会影响前十字带重建 (ACLR) 患者使用实时步态生物反 (RTGBF) 的步态修改. 这表明RTGBF甚至在ACLR后完全四头肌力量恢复之前也可能是有益的.
科学领域:
- 生物力学 生物力学
- 康复科学 康复科学 康复科学
- 整形外科 整形外科 整形外科
背景情况:
- 前十字带重建 (ACLR) 后的术后肌肉衰弱可能导致持续的异常步态生物力学.
- 四头肌软弱对ACLR患者使用实时步态生物反 (RTGBF) 修改步态的能力的影响尚不清楚.
研究的目的:
- 为了研究四头肌强度和改变垂直地面反应力 (vGRF) 能力之间的关联,在RTGBF干预过程中对患有ACLR的个体进行.
主要方法:
- 在一个研究实验室进行了一项横截面研究,涉及35名接受单边ACLR.个人.
- 参与者接受了基线步行试验和三项随机RTGBF试验,目标是5%,10%或15%的体重 (BW) 变化,达到峰值vGRF (pvGRF).
- 通过对pvGRF (ΔpvGRF) 的变化和对pvGRF相对于目标的根平均平方误差 (RMSE) 的变化,以及四头肌强度测量来评估步态变化.
主要成果:
- 在不同RTGBF目标 (5%,10%,15%BW) 中,四头肌强度和修改pvGRF (ΔpvGRF) 的能力之间没有发现显著的关联.
- 在任何RTGBF试验中,四肢强度与pvGRF的RMSE相对于反目标也没有显著的关联.
- 统计模型显示了因强度解释的最小差异 (R2 = 0.0030.025; P = .37.77),突出了缺乏关系.
结论:
- 四头肌强度大小似乎不会影响通过RTGBF干预在ACLR患者的步态修改的有效性.
- 这些发现表明,RTGBF干预可能对ACLR患者有益,无论他们目前的四头肌强度恢复水平如何.
- 可能不需要推迟RTGBF干预,直到ACLR后达到完全四头肌强度.

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...

Muscles that Move the Leg
1.4K
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...
