The human body is a structure designed in such a way that bone structures and soft tissues (muscles and ligaments) interact with each other both in static and dynamic situations in order to maintain balance and generate movement. Walking is a complex act resulting from the interactions between internal forces (muscles, joint constraints) and external forces (gravity, foot-ground reaction force) directed by an admirable postural and balance control system, which, through muscle contraction, exercises control over joint movements. This system allows man postural stability through the action of the antigravity muscles, both in a static position and in movement, adapting to continuous environmental changes. Anatomists and anthropologists over the years have explained how the anatomy and biomechanics of the pelvis have changed to adapt to the unique characteristics of bipedal walking [1]. They have shown us how the anterior rotation and the enlargement of the iliac wings, in addition to the structural change of the pelvis, are of fundamental importance for human bipedal gait because they modify the position and naturally the function of the hip abductor muscles (minimum and middle gluteus).
