Shout out @nickphysio ・ The tibialis posterior. An important player in the running and gait game. If you feel you have weak arches, flat feet, and/or get lots of shin splint pain from running, the tib post can be the focus. The foot is super complex and never an easy topic to discuss. Ok now hang tight, I’m bout to geek out.. The tib post plantarflex and invert the foot. It’s a major active supporter of the medial longitudinal arch, which acts eccentrically during the shock absorption phase of gait to prevent arch collapse, early midfoot pronation, & eversion of the foot. . So this post tib is firing hard to maintain the arch during heavy loading phase of gait and creating what we call the windlass mechanism. The windlass mechanism aka movement of the medial longitudinal arch is essential for shock absorption and dissipation of forces through the foot. The forefoot will then supinate & load at the big toe allowing for big toe extension push-off and enhancing that windlass mechanism. Plantarflexion w/ pressure through the great toe will allow for better pushoff and propulsion 🚀💨 • • EXERCISES Arch lifts Keep a tripod base distribution along the heel, ball of feet and outside feet. Try to lift your arch while keeping that tripod base. Even add a glute butt squeeze. You can see your arch lift. . Lateral step downs w/ arch lifts Keep an arch into step up. Then w/ step down slowly lower and pronate the arch (eccentric load). Repeat step up/arch up and then step down/arch down. . Progression This exercise leads to the next phase of gait w/ pushoff through the great toe. Keep the weight down on ball of feet prior to toe extension. Place a band under ball of feet. Pull on the band while performing a single leg heel raise. Try not to let the band slip off. Progress w/ doing single limb march to RDLs. • • Bolgla, L. A., & Malone, T. R. (2004).
