The rehabilitation protocol was identical for all patients and emphasized strengthening of abdominal muscles, stretching of the hamstrings, \u201ccore\u201d stability exercises, and trunk rotational movements in a pain\u2010free basis. Those patients with pain at rest and with daily life activities were also treated with a thoracolumbar orthosis.
