1. Anterior pelvic tilt is a pathological phenomenon in which the position of the pelvis is shifted, with the more correct pelvic position tilted forward by a certain angle. The most obvious symptom of anterior pelvic tilt is that the hips are protruding backward, and the waist-to-hip ratio, BMI and weight are all in the normal range, but the belly is still protruding forward. 2. Anterior pelvic shift, also known as slouching stance or rocking back, refers to the pelvis being pushed forward relative to the feet. Compared to the normal pelvic position, the pelvis of anteriorly shifted pelvis will be a little bit in front of the center line of the body, and at the same time, the position of the thorax may also form a relatively backward compensatory posture. People who are prone to anterior pelvic shift are: (1) Chest hunching, head forward: sedentary people. (2) Relative anterior displacement of the pelvis: pregnant women and men with large stomachs. 3. anterior pelvic tilt and anterior pelvic shift are closely related, are the lumbar spine and pelvis because of improper posture caused by a postural abnormality. null4. general anterior tilt, mostly refers to the angle of the abnormality of the anterior shift refers to the ligament laxity of the ligaments after the mild skewed and shifted, will cause pain and swelling of the lower limbs, and the prolapse of the visceral organs caused by abdominal pain, constipation, and so on. Generally, anterior deviation is more closely related to poor posture, while anterior displacement is generally more closely related to ligament laxity in pregnancy.
