Plantar flexion is the movement which increases the angle between the foot and the leg, as when depressing an automobile pedal. The word "Plantar" translates as "toward the sole" ("Planta").

The movement in the opposite direction is Dorsiflexion.

It occurs at the ankle.[1]

The range of motion for Plantar flexion is usually indicated in the literature as 30° to 40°, but sometimes also 50°.

The nerves are primarily from S1 and S2.
