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. These terms are used to resolve confusion, as technically extension of the joint is dorsiflexion, which could be considered counterintuitive as the motion reduces the angle between the foot and the leg.
