ANATOMY

Detailed explanation-1: -Loss of pelvic mobility forces hip motion to increase to accommodate postural change. Increased hip motion combined with change in the opening of the acetabulum increases the risk of impingement. * Hip stiffness can also reduce pelvic mobility because pelvic mobility is affected by both the spine and the hip.

Detailed explanation-2: -Movements at the pelvis Since there are two halves of the pelvis, each of them can move independently of one another. This is important, as this independent movement is necessary for walking, running, and many other movements. The pelvis can tilt anteriorly or posteriorly.

Detailed explanation-3: -A tilted pelvis can be caused by many factors including poor posture, muscle weakness or tightness, wear and tear on the joints in the pelvis from childbirth, or overuse. The angle of the pelvic tilt can change depending on the way that one is standing or sitting.
