What is dorsiflexion?

Dorsiflexion refers specifically to the movement that involves bending the foot upward at the ankle joint. This action decreases the angle between the top of the foot and the front of the leg, allowing the toes to point toward the shin. It is a fundamental movement that is important for various activities such as walking, running, and climbing stairs because it enables the heel to strike the ground while keeping the toes elevated.

In contrast, bending the foot downward increases the angle between the foot and the leg, which is referred to as plantarflexion. The actions of extending the leg forward and rotating the ankle describe different motions that do not specifically involve the upward bending of the foot. Understanding dorsiflexion is crucial for recognizing how movements in the ankle contribute to overall mobility and balance.
