概括

前十字带重建 (ACLR) 患者在坐的上升阶段表现出较大的四肢负荷不对称性. 康复应该专注于神经肌肉控制和运动速度,以减少这些不平衡.

科学领域:

生物力学生物力学
整形外科整形外科整形外科
康复科学康复科学康复科学

背景情况:

前十字带重建 (ACLR) 往往导致在功能运动期间持续的四肢不对称.
了解这些不对称性在坐等炼期间对于有效的康复至关重要.

研究的目的:

在ACLR后6个月的个体中,调查坐的各个阶段的肢体间负荷差异.
为了确定坐阶段是否影响生物力学不对称性.

主要方法:

35名患有ACLR的参与者通过3D运动捕捉分析了体重坐.
计算的垂直地面反应力冲动 (vGRFi),膝盖曲时刻冲动 (KFMi) 和部至膝盖曲时刻冲动比 (HKRi).
计算了四肢间比率 (ILR),并记录了式阶段的持续时间.

主要成果:

在上升阶段观察到更大的不对称性 (vGRFi ILR,KFMi ILR,HKRi ILR).
上升阶段的速度明显快于下降阶段.
在控制运动时间后,ILR的相位特异性差异并不显著,但膝盖特异性的负载不对称性仍然存在.

结论:

坐上升阶段与ACLR个体的肢体和膝盖负荷不对称性增加有关.
运动速度影响这些不对称性,强调了在康复期间神经肌肉控制的重要性.
持续的膝关节特异性负荷不对称性需要ACLR后的有针对性的干预措施.

关键词:

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

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...

Knee Joint

Knee Joint

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...

Muscles that Move the Leg

Muscles that Move the Leg

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...
