The correct sleeping position for posterior pelvic tilt is to sleep in the supine position. If the pelvis tilts back, the patient had better rest in the supine position. In the supine position, both lower limbs should be straightened as much as possible to correct the posterior pelvic tilt by pulling the connection between the lower limbs and the pelvis. At the same time, it is better to pad soft pillows in the lumbar area to make the pelvis have a tendency to tilt forward, which can also improve the posterior pelvic tilt. Generally, after several methods of treatment above, the clinical symptoms of posterior pelvic tilt will be improved to some extent in about 3-6 months. Patients should also strengthen the strength training of the muscles around the pelvis, such as the abdominal muscles, lumbar back muscles, resistance training can make the strength significantly increased, so as to improve the balance of weight bearing in the front and back of the pelvis and alleviate the clinical symptoms of posterior pelvic tilt.
