Abstract: The machine of the present invention measures and records in terms of the orientation planes of motion the presence of, the location, of and the severity of the postural distortion-stress effects of C-1 subluxations on the human body, making possible thereby statistical analyses between C-1 misalignments (determined by X-ray analysis) and such postural distortion-stress effects on the skeletal framework as directly result from the misalignment interferences of C-1 on the nervous system and its normal functioning. This machine can demonstrate the postural distortion-stress effects of C-1 subluxation on the spine by checking the malpositional relationships of upper thoracic vertebral segments and pelvis prior to and subsequent to C-1 correction, indicating thereby the corrections obtainable throughout the spine and thus reducing the need for repeated applications of X-radiation to the patient.

Abstract: A headpiece is provided for the head end of a table on which a patient lies on a side to have the bottom side of the head engage the headpiece. A plurality of pads are adjustable by the headpiece support so that the head is retained in a fixed position while a chiropractor makes a vertible adjustment.

Abstract: The process of the present invention comprises the steps of, and means for, etermining the location of vertebrae in the human spine relative to each other. The process establishes accurately the location of the atlas vertebra in all of its planes in relationship to the occiput and subjacent vertebrae including specifically the dorsal vertebrae and pelvis. The process is useful in the determinaion of, and correction of, any misalignment of the atlas vertebra, the head and/or pelvis and their supporting spinal vertebrae.

Abstract: The machine of the present invention measures and records in terms of the ientation planes of motion the presence of, the location of and the severity of the distortion-stress effects of C-1 subluxations on the human body, making possible thereby statistical analyses of reciprocal relationships between C-1 misalignments (determined by X-ray analysis) and such distortion-stress effects on the skeletal framework as directly result from the misalignment interferences of C-1 on the nervous system and its normal functioning. The machine can demonstrate the distortion-stress effects of a C-1 subluxation on the spine by checking the malpositional relationships of key vertebral segments along the spine prior to and subsequent to C-1 correction, indicating thereby the corrections obtainable throughout the spine and thus reducing the need for repeated applications of X-radiation to the patient.
