To bend or flex the foot and toes upward toward the shin, or to move a body part toward its dorsal surface.
From 'dorsi-' (back) combined with 'flex' from Latin 'flexus' (bent/folded). The term describes movement toward the dorsal aspect of a joint.
Dorsiflexion is the movement that makes your shin muscles burn during certain workouts—athletes train this movement because strong dorsiflexion helps prevent ankle injuries when running!
