Lying on the waist is not necessarily anterior pelvic tilt, the normal population in lying on the waist can be suspended, because the lumbar spine has anterior curvature of the physiological curvature of the lumbar vertebrae, in most cases can be passed through the thickness of the patient’s palm, such as lumbar spine suspension, can easily pass through the palm of the hand thickness of the object, then for anterior pelvic tilt. Anterior pelvic tilt is the forward rotation of the pelvis along the sagittal axis resulting in the lumbar vertebrae protruding forward and the hips protruding backward. The patient usually manifests that he/she cannot maintain the sleeping position of lying down for a long time, and he/she will feel pain in his/her lower back, and he/she is unable to keep his/her lower back close to the wall when standing against the wall, and his/her buttock muscles and abdominal muscles are weak and easy to be fatigued. You can wear negative heel shoes to make the body’s center of gravity shift backward, the pelvis rotates backward on the sagittal axis, which can correct the anterior pelvic tilt and lumbar curvature, and at the same time, you should insist on exercising the buttock muscles and abdominal muscles, so as to equalize the strength of the muscles around the lumbar spine and pelvis.
