Dorsiflexion (Dorsal Flexion)

Follow on Youtube

Dorsiflexion: Also called dorsal flexion. A principal flexion movement of the ankle resulting in the top of the foot moving toward the front of the lower leg (anterior tibia bone). The normal range of motion for dorsiflexion is approximately 20°. Dorsiflexion can simply be called "ankle extension" although the midfoot does contribute to the range of motion of this extension movement.

This movement takes place in the sagittal (or frontal) plane, which is the plane in which ankle movement primarily occurs. The opposite of dorsiflexion is plantar flexion.
