ROTATIONAL STEP & LEAN Do you struggle with falling or feeling like you are going to fall when you change directions or rotate your body? You are not alone.

This lack of coordination and balance comes from slow or disrupted signaling between the balance sensor in your cerebellum (small organ at the base of your brain).
