Being able to walk normally but not being able to bend over after the symptoms of lumbar pain have arisen is a common feature of most disorders of the lumbar region. This is mainly due to the fact that when walking in an upright position, the load on the waist is relatively small, and there is relatively little compression and irritation on the site of the lumbar lesion, so the symptoms that trigger lumbar pain are also relatively light. In the process of bending, the burden on the waist will increase significantly, generally at least 50% increase, in the process of bending will make the lumbar lesion site by obvious provocation and stimulation, so that the symptoms of lumbar pain significantly aggravated, will be born lumbar pain in the upright walking less, but there is no way to bend the symptoms.
