What is the Tibialis Anterior?
The tibialis anterior is a muscle on the front and slightly outside of your lower leg, running alongside the shin bone. If you slide your hand down the front of your shin and then move a little toward the outside, that’s the area where it sits. Its main jobs are to lift your foot upward at the ankle, called dorsiflexion, and to help turn the sole of your foot slightly inward, called inversion. Every time you take a step, it plays a major role in controlling how your foot meets the ground. When your heel touches down, the tibialis anterior works like a brake to lower the front of your foot smoothly instead of letting it slap the floor. When you swing your leg forward, it lifts your toes so you don’t catch them.
