- 在跨斜坡行走期间,骨截肢患者 (TFAs) 上下肢协调的适应仍然不清楚.
研究的目的:
- 为了研究TFAs如何调整他们的上下肢协调,当走在横斜坡的表面.
- 为了比较TFA和健康成年人 (Ctrl) 在平坦地面和横斜坡条件下的协调模式.
主要方法:
- 对20名TFA和20名Ctrl参与者进行了三维步态分析.
- 分析了 Sagittal 平面关节角度和部和肩膀的速度.

01:16Bones 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 neck...
01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:28Muscles of the Leg that Move the Foot and Toes
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.
