Spinal Posture (IMAGE) The Gerontological Society of America Caption A team of researchers based in Japan discovered that the trunk angle of inclination -- the angle between the true vertical and a straight line from the first thoracic vertebra to the first sacral vertebra -- is associated with becoming dependent on help for activities of daily living (ADL). The subjects in the highest quartiles, who had the greatest angle of spinal inclination, were 3.47 times more likely to become dependent in ADL than those in the lowest quartiles (the group with the least spinal inclination), even after adjusting covariates such as age, sex, back pain, and stiffness.
