Since human being evolved form reptile, lumbar spine has loaded our body weight about 2/3 day time. We do daily activities with the body weight on lumbar spine, so it over loaded day by day. Compared with the other organs, lumbar spine will be got sick or you can say early degeneration. Again under the bad external force and other pressure, fibrosus of lumbar disc is very easy to be broken and the nucleus pulposus will be oppressed out on the nerve root or venous plexus in vertebral canal. The result is that the venous return would be blocked which could deteriorate the ischernia and anoxia around nerve root, increase the lactic acid and pH indicator thickness. These kinds of acidic metabolite and inflammation-causing substances could arouse lower and legs pain, numbness even sexual malfunction, gatism, and paraphysis of the lower limbs that is lumbar disc herniated. Some other lumbar disc diseases are directly and indirectly related with lumbar disc herniated such as Spinal Stenosis, vertebra unsteadiness, spondylolisthesis, hyperosteogeny, degenerative disease on lower back. As for the causes of these diseases there comes a result that is lumbar disc disease is a kind of essential product of human beings development. The basic cause of lumbar disc herniated is pressure so professors figure out that unload pressure is the key point in cure lumbar disc disease.

Space Medical Practice –History of “Four-Dimensional Treatment”First Deputy Director General of Chinese Medical Doctor Association, Head of Junwei High Technique Institute, National Defense Senior Engineer, Mr Feng Guo-zhu has several years working experience as a designer of outer space engine. Mr Feng got the opportunity always working in the zero gravity simulation laboratory and felt comfortable and relieved from lumbar disc disease but the pain come back after walked out the laboratory, lying feel better but deteriorate when standing up. So Mr. Feng analyzes that the symptom will be deteriorated when over loaded and relieved unloaded. With this found, Mr. Feng invented “Four-dimensional Treatment” for cure lumbar disc disease with other space medical professors.
