How does the ankle joint move?
How does the ankle joint move?
The movements that occur at the ankle joint are plantarflexion, dorsiflexion, inversion, and eversion. The muscles of the leg divide into anterior, posterior, and lateral compartments.
What are the 4 movements your ankle can do?
In total, the ankle allows the foot to move in six different ways: dorsiflexion, plantarflexion, inversion, eversion, and medial and lateral rotation. Flexion and extension at the ankle are referred to as dorsiflexion and plantarflexion, respectively (Figure 2).
What is subtalar joint motion?
The kinematics of the subtalar joint allows the combined motions of inversion/adduction and eversion/abduction of the rearfoot (Fig. 11.15). (Recall that these motions are components of supination and pronation, respectively.)
What is ankle range of motion?
A normal ankle moves from approximately 20° dorsiflexion, to 50° plantar flexion. A range of 24° to 30° combined motion (dorsiflexion and plantar flexion) is needed for normal walking, 37° is needed for ascending stairs, and 55° is needed for descending stairs.
What makes the ankle joint stable?
Stability in the ankle joint is secured passively in part by the shape of the bones that make up the joint – i.e. the distal part of the tibia with the medial malleolus, the lateral malleolus and trochlea of the talus – and partly the ligamentous structures which surround the joint laterally, me- dially and between the …
Which movement has the greatest range of motion in the ankle joint?
Motion of the ankle occurs primarily in the sagittal plane, with plantar- and dorsiflexion occurring predominantly at the tibiotalar joint. Several studies have indicated an overall ROM in the sagittal plane of between 65 and 75°, moving from 10 to 20° of dorsiflexion through to 40–55° of plantarflexion.
Which joints do not allow movement?
Fibrous joints – the bones of fibrous joints are joined by fibrous tissue, such as the sutures in the skull or the pelvis. Fibrous joints allow no movement at all. 2.
What are the two primary movements of the ankle?
The main action of the ankle joint is to allow dorsiflexion and plantar flexion of the foot, as well as some degree of pronation and supination with subtalar and midtarsal joints. The joint also acts as a shock absorber as the heel strikes the ground during the first phases of gait.
Is subtalar joint part of ankle?
The subtalar joint, also known as the talocalcaneal joint, is a compound joint positioned directly below the ankle joint. 1 It is comprised of the calcaneus (heel bone) and a column-shaped bone called the talus.
What is the ankle joint called?
Talocrural joint
The ankle joint, or Talocrural joint, is a large synovial joint. It is a hinge joint that allows plantarflexion and dorsiflexion, moving the foot up and down. The ankle is more stable while joint is in dorsiflexion, and the anterior part of the talus is held in the joint.
How do I stabilize my ankle joint?
Compression helps decrease swelling and provides stability to your ankle by immobilizing it. You should apply a compression bandage as soon as a sprain occurs. Wrap your ankle with an elastic bandage, such as an ACE bandage, and leave it on for 48 to 72 hours. Wrap the bandage snugly, but not tightly.
