M.Tech. / According to the “Lovett Reactor” as explained by Walther (2000), the Atlas and the 5th lumbar vertebrae rotate in the same direction when a person walks. This relationship continues throughout the spinal column as 3rd cervical vertebrae (C3) rotates in the same direction as 3rd lumbar vertebrae (L3). From this point the movement changes to counter-rotation as 4th cervical vertebrae (C4) counter-rotates to 2nd lumbar vertebrae (L2) and 5th cervical vertebrae (C5) to 1st lumbar vertebrae (L1). According to Inman, Ralston and Todd (1981) this correlation extends as the Sacrum reacts with the Occiput. Thus, there is clinical verification demonstrating that the Lovett Reactor vertebrae are often interrelated to primary and compensatory subluxations. The aim of this study was to determine the effect of Chiropractic Occipital adjustments versus Chiropractic Sacroiliac adjustments in the treatment of chronic Lumbar Sacral pain.
