Abstract
An improved chiropractic adjusting instrument is provided for use in spinal manipulative therapy and for exciting a human spine at preselected resettable frequencies within the range of its natural frequency. The improvement comprises providing a repositionable and resettable shaped mass adjacent to the thrust element; a longitudinally shiftable and rotatable sleeve portion on the shaped mass enables setting the frequency to a predetermined number of preselected settings that are easily and positively fixed so that inadvertent changes in frequency will not occur in use.
