Pelvic tilt

Forms

• Anterior pelvic tilt is when the front of the pelvis drops in relationship to the back of the pelvis. For example, this happens when the hip flexors shorten and the hip extensors lengthen.
• Posterior pelvic tilt is the opposite, when the front of the pelvis rises and the back of the pelvis drops. For example, this happens when the hip flexors lengthen and the hip extensors shorten, particularly the gluteus maximus which is the primary extensor of the hip.

• Lateral pelvic tilt describes tilting toward either right or left and is associated with scoliosis or people who have legs of different length. It can also happen when one leg is bent while the other remains straight, in that case the bent side's hip can follow the femur as knee lowers towards the ground.
