PLANTAR FLEXION. Plantar flexion of the ankle occurs when the dorsum of the foot lengthens in line with the leg, or points downward (as in depressing the accelerator in a car). Plantar flexion angle is much greater than that of dorsiflexion; ROM is zero to 50 degrees.1  Gastrocnemius.lthough inversion and eversion are actions not of the ankle joint but of the foot, the musculature within the lower leg acts directly on the foot and needs no assistance from other muscles to create motion.
