Plantar flexion

pushing or pointing the toes and the ball of the foot down towards the ground

Dorsiflexion

Standing on the heel of the foot, with the toes pointed up towards the sky

Lateral ankle sprain

injury to the ATF, CF, and PTF

Medial ankle injuries MOI

Eversion (ankle rolls inward)

Medial ankle injuries S/S

high force required, foot planted on ground + eversion, pain over medial ankle ligaments

High ankle sprains

injury to ligaments above the mortise to the syndesmosis
