To determine anterior pelvic tilt you can observe the abdomen and hips, observe the anterior superior iliac spine, and take X-rays. 1. Standing position waist back head close to the wall, under normal circumstances waist and wall no gap, if the gap is larger consider anterior pelvic tilt, if the abdomen has obvious protruding and buttocks back consider anterior pelvic tilt. 2. Lying flat on the bed, supine position, the waist and trauma close to the normal anterior superior iliac spine does not exceed the pubic symphysis, if it exceeds the pubic symphysis consider anterior pelvic tilt. 3. Judge by taking lumbar vertebrae front and side position film and pelvic film. Through the above methods, we can judge the anterior pelvic tilt, and change the bad posture, which can be corrected by manipulation or rehabilitation exercise.
