7 Σεπ 2024 · Flexion refers to a movement that decreases the angle between two body parts. Flexion at the elbow is decreasing the angle between the ulna and the humerus. When the knee flexes, the ankle moves closer to the buttock, and the angle between the femur and tibia gets smaller. Extension refers to a movement that increases the angle between two body ...
In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. For the upper limb, all anterior motions are flexion and all posterior motions are extension.
20 Ιουλ 2023 · Both movements happen at the ankle joint. Dorsiflexion means flexion of the dorsum (top) part of the foot by reducing the angle between it and the anterior surface of the leg. It happens when you lift the front part of your foot while keeping your heel on the ground.
Foot drop is inability to lift the forefoot due to the weakness of dorsiflexors of the foot. Ankle and foot dorsiflexors, namely the tibialis anterior, extensor digitorum longus, and extensor hallucis longus, help clear the foot during the swing phase of walking and control plantar flexion of the foot on heel strike.
25 Σεπ 2024 · In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint. For the upper limb, all anterior-going motions are flexion and all posterior-going motions are extension.
Knee flexion is the bending of the knee to bring the foot toward the posterior thigh, and extension is the straightening of the knee. Flexion and extension movements are seen at the hinge, condyloid, saddle, and ball-and-socket joints of the limbs (see Figure 1a-d).
Dorsiflexion and plantar flexion refer to extension or flexion of the foot at the ankle. These terms refer to flexion in direction of the "back" of the foot, which is the upper surface of the foot when standing, and flexion in direction of the sole of the foot.
