• Anterior pelvic tilt (APT) is a postural pattern in which the front of the pelvis drops in relationship to the back of the pelvis. For example, this results from the
hip flexors shortening and the
hip extensors lengthening. It is also called
lumbar hyperlordosis, which is characterized by an exaggerated curve in the lower back. • Posterior pelvic tilt (PPT) is the opposite: 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 (LPT) 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. • In left pelvic tilt, the right side of the pelvis is higher than the left side. • In right pelvic tilt, the left side of the pelvis is higher than the right side. ==Treatment==
