The methods of determining anterior and posterior pelvic tilt are as follows: First, observe the abdomen and hips: if there is anterior pelvic tilt, the abdomen will obviously protrude forward, while the hips will protrude backward, and the patient will have the performance of posterior hip, which is most obvious in the standing position, and the patient with posterior pelvic tilt will have obvious sagging of the hips. Second, observe the anterior superior iliac spine: if there is anterior pelvic tilt, the anterior superior iliac spine will obviously exceed the pubic symphysis and be in front of the pubic symphysis, while in posterior pelvic tilt, the anterior superior iliac spine will not exceed the pubic symphysis, when the pubic symphysis is in front instead. Through the above methods, it is easy to determine the anterior or posterior pelvic tilt, and if the diagnosis is confirmed, early treatment should be carried out to correct it, so that the clinical symptoms can be relieved quickly. Patients should also pay attention to maintain normal posture to avoid anterior or posterior pelvic tilting.
