What does dorsiflexion mean and what is dorsal extension, plantar flexion?

The toe is upward, and the angle between the foot and the calf is less than 90° is called dorsiflexion, and conversely, the toe is downward, and the angle between the foot and the calf is greater than the right angle is called plantar flexion.

The deltoid ligament mainly restricts dorsiflexion of the foot and is located on the medial side of the joint. It originates from the medial malleolus and fan-shapes down to the three bones of the talus, heel and scaphoid.

The toe is raised, and the dorsum of the foot is brought closer to the front of the calf for the extension of the ankle joint, which is customarily called dorsiflexion, and the toe drop is the flexion of the ankle joint, which is customarily called plantar flexion.

The back of the foot is flexed and taut, a bit like the ballet instep

1. Plantar flexion: the toe is drooping, and the dorsum of the foot is far away from the front of the calf for the flexion of the ankle joint, also known as plantar flexion.

2. Dorsidosis: It refers to the lifting of the toes, the dorsum of the foot to the front of the calf, and the range of normal ankle dorsal extension is 20 to 30 degrees.

Toe force in different directions:

1. Plantar flexion: The direction of plantar flexion is upward.

2. Dorsflexion: The direction of the back extension of the toe is facing downward.

Indorsal foot extension: that is, the foot moves to the front of the calf, which is commonly known as "hooking the foot", if the calf is counted as a baseline horizontal line, the action that can make the angle between the dorsum of the foot and the calf less than 90 degrees is the dorsal foot extension, which is mainly completed by the extensor pollicis longus tendon of the dorsum of the foot and the tendon contraction of other four-toe extensor tendons, and the protrusion of the dorsal foot tendon can be seen when the dorsum of the foot is extended.

Foot dorsiflexion: When the ankle is in the normal functional position, the tibial anterior muscle contractions, resulting in the movement of the dorsum of the foot upturned (that is, the angle between the dorsum of the foot and the anterior tibia is reduced, and the distance is close), the common saying "stretch the foot", the angle between the dorsum of the foot and the calf is greater than 90 degrees, and the foot moves towards the direction of the soles of the foot, which is the dorsiflexion of the foot.

One meaning, the correct name is plantar flexion and dorsal extension. That is, the meaning of letting the foot go down and up hook.

If you don't have anatomical knowledge, don't mistake people's children.

The dorsum of the foot and the front of the calf are the extensor tendons, and the action caused by the contraction is the dorsum flexion of the foot; Behind the soles and calves are the flexor tendons, which cause plantar flexion (dorsal extension).

Stroke** Step 50 foot dorsiflexion combination exercise allows hemiplegic patients to land with their heels first when walking.

Indorsal extension: the foot is stretched and relaxed, and dorsiflexion of the foot: the foot is arched and curled up.
