ABSTRACT:
An improved chiropractic adjusting instrument is provided for use in spinal manipulative therapy and for exciting a human spine at its natural frequency. The chiropractic adjusting instrument includes a thrust element for delivering an input force, a body contact member removably attached to the thrust element, a spring means for propelling the thrust element and the body contact member outwardly, and an adjustment knob arranged on the thrust element for adjusting the amount of potential energy imposed on the spring means and for controlling the magnitude of the resulting input force. In use, the input force is mechanically tuned to a desired frequency (e.g., the natural frequency of a human spine) by positioning a shaped mass on the thrust element. By mechanically tuning the chiropractic adjusting instrument in this way, the dynamic output response of the spine is maximized while the requisite impact force is minimized. This not only enhances the overall effectiveness of spinal manipulative therapy, but also reduces the possibility of damage to the vertebrae during such treatment.
