Is the ankle more stable in dorsiflexion or plantarflexion?

The talus is wider anteriorly and more narrow posteriorly. It forms a wedge that fits between the medial and lateral malleoli making dorsiflexion the most stable position for the ankle.

What is the difference between dorsiflexion and plantar flexion of the foot?

Dorsiflexion involves just lifting the foot. Plantar flexion involves lifting the whole body. So it’s not surprising that the muscles for plantar flexion are much larger than the ones for dorsiflexion. There’s one muscle on the front of the leg for dorsiflexion, tibialis anterior.

What happens at the ankle during dorsiflexion?

Dorsiflexion occurs in your ankle when you draw your toes back toward your shins. You contract the shinbones and flex the ankle joint when you dorsiflex your foot. You can also dorsiflex your foot by lifting the ball of your foot off the ground while standing, keeping your heel planted into the ground.

What joint does dorsiflexion and plantarflexion?

The ankle joint (or talocrural joint) is a synovial joint located in the lower limb. It is formed by the bones of the leg (tibia and fibula) and the foot (talus). Functionally, it is a hinge type joint, permitting dorsiflexion and plantarflexion of the foot.

What is the difference between plantar and dorsiflexion?

They refer to the two surfaces of the foot; the dorsum (superior surface) and the plantar surface (the sole). Dorsiflexion refers to flexion at the ankle, so that the foot points more superiorly. Plantarflexion refers extension at the ankle, so that the foot points inferiorly.

What’s the difference between plantar and dorsiflexion?

The main difference between dorsiflexion and plantar flexion is that dorsiflexion is the action which decreases the angle between the leg and the dorsum of the foot whereas plantar flexion is the action which decreases the angle between the back of the leg and the sole of the foot.

What muscles do ankle inversion?

There are two muscles that produce inversion, tibialis anterior, which we’ve seen already, and tibialis posterior. The other muscle that can act as a foot invertor is tibialis anterior, which inserts so close to tibialis posterior that it has almost the same line of action.

What is the difference between dorsiflexion and plantar flexion?

Dorsiflexion and plantar flexion are two special movements of the flexion of the foot. The joint that is involved in the dorsiflexion and plantar flexion is the ankle joint. The main difference between dorsiflexion and plantar flexion is that dorsiflexion is the action which decreases the angle between the leg and the dorsum …

Is the ankle joint involved in dorsiflexion?

Dorsiflexion refers to the flexion of the foot in the upward direction. It is the backward bending and contracting of the foot. In the foot, the ankle joint is involved in the dorsiflexion.

Which is the correct description of foot flexion?

Flexion and extension of the foot 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.

Which is the correct range of motion for plantar flexion?

Plantar flexion refers to a movement of the foot in which the foot and toes flex towards the sole. This means the foot points towards the floor during plantar flexion. The normal range of motion is 20 to 50 degrees.

Dorsiflexion refers to the flexion of the foot in the upward direction. It is the backward bending and contracting of the foot. In the foot, the ankle joint is involved in the dorsiflexion.

What are the movements of the ankle joint?

The ankle joint is a hinge type joint, with movement permitted in one plane. Thus, plantarflexion and dorsiflexion are the main movements that occur at the ankle joint. Eversion and inversion are produced at the other joints of the foot, such as the subtalar joint.

Which is involved in plantar flexion of the ankle?

All three structures are involved in plantar flexion of the ankle, and thus, should any of these three structures (gastroc., soleus, or Achilles tendon) be short or tight, it limits the ability to achieve dorsi-flexion (indicated by the arrow).
