Abstract
A therapeutic device for reversing osteoporosis in human limbs which comprises a crank assembly adapted to attach to the distal ends of a pair of human limbs such as the legs, a motor for rotating the crank assembly so that the limbs move along a predetermined path, a vibrator for vibrating the crank assembly, thereby transmitting vibrations to the limbs, and a control for regulating the amplitude of the vibrations transmitted to the limbs. In a preferred embodiment, the control includes an accelerometer adapted to be mounted on a supported limb to generate a signal proportional to the amplitude of the vibrations actually felt by the limbs. The signal is used to modify the amplitude of electric current generated by the control to power the vibrator such that the amplitude of driving vibrations generated by the vibrator is proportional to the amplitude of vibrations felt by the limbs so that the amount of vibration of the limbs is maintained within a predetermined range.
