Forty patients were analyzed by full spine (14"x36") radiographs in both sitting (A to P and lateral) and standing (A to P and lateral) positions. Their radiographs were analyzed for distance from center of gravity, pelvic drop, occipital, atlas (C-1), T1, T12 and Sacral angles plus the degree and level of thoracic kyphosis. Each patient took a Minnesota Multiphasic Personality Inventory (MMPI) test. The authors then analyzed the data from the radiographs and MMPI for any correlations between psychological expression and spinal indicators.
Among the findings: Atlas angle (the measure of the number of degrees the atlas deviated from the horizontal plane) correlated to three MMPI scales: hypochondriasis, hysteria and paranoia in both standing and sitting films; the degree of the thoracic curve correlated with the hypomania scale (depression and low energy) only in the standing films and the pelvic drop correlated with "need for nurturing" in the sitting films. These findings seemed to agree with Dr. Lowell Ward's Spinal Column Stressology observations. The chief author (Dr. Koren) wishes to expand this pilot study as more research in this area is badly needed.
