What is the definition of dorsiflexion?

Dorsiflexion is defined as the movement of the foot where the toes are brought closer to the shin. This action involves the lifting of the front part of the foot and is primarily associated with activities such as walking and running, where the foot needs to clear the ground to prevent dragging. This term specifically refers to the movement at the ankle joint that decreases the angle between the dorsum (the top) of the foot and the leg.

Understanding this term is crucial, especially in contexts like rehabilitation and exercise science, where movements need to be defined accurately to ensure proper technique and to prevent injury. The other options describe different movements: the return to anatomical position, lateral bending of the spine, and movement toward the anterior surface, which are not related to the specific action of dorsiflexion.
