First, posture and position When standing position, the lumbar anterior convexity increases, which aggravates the pressure of lumbar vertebral joints and intervertebral discs, therefore, standing for a long time will cause lumbago. 1, if in the standing process can make bilateral knee joints take turns to maintain a mild flexion position, can reduce the lumbar anterior convexity; 2, abdominal chest, shoulders relaxed, eyes flat, head and shoulders, knees, hips and ankles in a straight line, to keep the lumbar vertebrae mildly anterior convexity. High heels will increase the anterior pelvic tilt and increase the strain on the lumbar region. Prevention: long-term high-heeled shoes patients are best often in a lying position when the knees will be held in front of the chest, or often squatting hands holding the knee, to prevent the occurrence of lumbago.
