Determine the anterior and posterior pelvic tilt, depending on your standing position. Make your heels stand against the wall, with your buttocks as well as your back pressed against the wall and your waist as close to the wall as possible. If the depression between the waist and the wall is more than one fist distance, there may be anterior pelvic tilt. Both anterior and posterior pelvic tilt are caused by incorrect standing posture, such as the stomach being raised and the waist being arched forward. The elderly are prone to anterior pelvic tilt, i.e., unconscious hunching of the back, but the head is backward and the pelvis and stomach are forward, and if they stand unsteadily, they may walk with their hands on their backs. The common manifestation of anterior pelvic tilt is low back pain, like to stretch, or feel uncomfortable when changing sitting and standing postures, which is aggravated when osteophytes appear.
