Abstract
Abstract A novel side-posture table for use by chiropractors and other members of the healing arts in order to relieve the patient from the pain and suffering resulting from displaced portions of the upper-cervical section of his or her spine. A novel headrest portion is provided, with respect to which the head of the patient can be painlessly immobilized, thus enabling the chiropractor to apply adjustic thrusts as may be necessary in the proper treatment of a patient without the patient's head tending to move undesirably at such times, which motion would have the effect of greatly diminishing the value of the adjustment being made. Inasmuch as accurate and very precise movements of the atlas vertebra are to be brought about, the design of our machine is such as to enable the patient to lie on either side, facing the direction appropriate for his circumstances. Advantageously, our novel headrest arrangement can be selectively varied in a heightwise sense in order to dispose the patient's vertebral members between the upper-cervical and the mid-cervical spine in the most appropriate configuration from the standpoints of his conditions of vertebral displacement and the type of adjustic remedy to be applied. In addition, the headrest can be moved in tilt at the behest of the chiropractor until such time as the novel mastoid support portion of the headrest is in such position with respect to the mastoid bone of the patient as to minimize any tendency of the head to rock or tilt during the administration of the forthcoming treatment. Additionally, our novel machine utilizes an electrical push-button arrangement such that the chiropractor can make rapid yet precise movements of the headrest so as to best accommodate the patient, with an ancillary feature of our invention involving an automatic regime, in which the headrest can be caused to automatically return to the height and tilt positions previously found to be optimum for the patient about to undergo treatment.
