ABSTRACT:
An apparatus and method for preventing and therapeutically treating osteoporosis are provided. The apparatus includes a magnetic field generator for producing a controlled, fluctuating, directionally oriented magnetic field parallel to a predetermined axis projecting through the target bone or skeletal system. In one aspect, a field detector samples the magnetic flux density along the predetermined axis and provides a signal to a microprocessor which determines the average value of the flux density. The applied magnetic field is oscillated at predetermined frequencies to maintain a preselected ratio of frequency to average flux density which controls osteoporosis. This ratio is maintained by adjusting the frequency of the fluctuating magnetic field and/or by adjusting the intensity of the applied magnetic field as the composite magnetic flux density changes in response to changes in the local magnetic field to which the target bone is subjected.
