In this study, 579 subjects with chronic and recurrent back pain were randomized to receive massage, six Alexander Technique lessons, 24 Alexander Technique lessons, or no intervention. In addition, half of the subjects were encouraged to walk regularly. A year later, the group with no intervention had 21 days of pain per month. The group with massage had 14 days of pain per month. The group with six Alexander Technique lessons reported 11 days of pain per month, and the group with 24 Alexander Technique lessons reported three days of pain per month. There were no adverse effects.
