We cannot equate this with a purely biological freedom or vitality, or spontaneity. Bergson and His Philosophy J. Alexander Gunn. It is a more serious difficulty that Paul knows of no Longobardic king with a name which we can equate with Sceaf.
But this posture makes your pelvis rock forward into an anterior pelvic tilt, which consequently creates an increased lumbar curve (lordosis). Unfortunately, other tissues such as the muscles described above adapt to this posture over time, which contributes to back pain and injury.
In addition, they cite rotation of the lumbar spine as a function of the QL on the contralateral side to the direction of rotation. They consider this muscle to be the most frequent cause of low back pain of muscular origin, an observation with which I agree strongly. patient presenting with chronic low back pain is asked to side bend laterally, sitting in a chair with the pelvis stabilized. The contralateral QL is expected to function as an eccentric guy wire to side bend away from the active QL, and then function concentrically to return the trunk to the upright position.
