One of the most important structures for this control is the medial plantar vault (MPA), an important structure in the absorption of impact and essential for the function Foot. The deformation of the MPA in the gait support phase absorbs the Energy and propels the limb, to perform this biomechanical function the MPA must Stable from the anatomical point of view, which is conferred by the bone architecture and But also by the performance of the intrinsic and extrinsic musculature of the Feet. The fall of the MPA, decreases the stability of the foot, limits its biomechanical function,
