A revolutionary program—Back Power—has been created by an occupational health physician and a chiropractor. Together, Imrie and Barbuto challenge the notion of ``physician versus chiropractor,'' bringing an interdisciplinary approach to the problems associated with the diagnosis, treatment and management of back pain—with resounding success.
