Osteoporosis
                                is characterized by an excessive loss of the
                                bone matrix. 
                              Let me remind you that bones have two types of
                              cells: osteoclasts that reabsorb bone substance
                              (destructive phase), and osteoblasts that make
                              bones (constructive phase). 
                              Both types of cells coexist in a state of dynamic
                              balance. When osteoclasts predominate, a loss of
                              the bone matrix (reabsortion) will occur, and when
                              activity of osteoblasts is dominant, a greater
                              production of bone will take place (osteoformation). 
                              Osteoporosis is as much influenced
                                by factors such as: nutrition, medication and
                                lifestyle. Clinical doctors try to stop the destructive
                                function of osteoclasts and to increase the formation
                                of bone (osteoblasts) prescribing Vitamin D,
                                hormones (estrogens, progesterone, calcitonine)
                                and mineral supplements (calcium, magnesium,
                                phosphorous, manganese, fluor and borous). Finally,
                              they recommend different types of exercise.  
                              In regard to the mechanic
                                  factor,
                                I would like to remind you that the weight of
                                a body is the result of terrestrial gravity force
                                  vertically acting on the skeleton. In an upright
                                position, the weight that is transferred to the
                                bones and reaches the floor, stimulates bone
                              manufacturing cells (osteoblastos). 
                              An example of the importance
                                of the mechanic factor in the appearance of osteoporosis
                                takes place in people with important postural
                                disorders for example, with important deformations
                                of the vertebral spine (xifosis, scoliosis). 
                                Another example of mechanical disorders takes
                                place in patients that remain in bed for a long
                                period of time.  
                                In a similar way, astronauts that must stay in
                                space for a prolonged period of time, experience
                                osteoporosis as a consequence of the lack of
                              weight (ingravity) upon their return to Earth. 
                              Neurocranial Restructuring can
                                improve the degree of osteoporosis in cases originated
                                from a mechanic factor (gravity body disfunction). 
                                Let me tell you that N.C.R. does not replace
                                classic drug treatments; it is a complimentary
                                resource.
