"Subluxation syndrome is a legitimate, potentially testable, theoretical construct for which there is little experimental evidence… Failure to challenge subluxation dogma perpetuates a marketing tradition that inevitably prompts charges of quackery… We lament efforts to generate unity within the profession through consensus statements concerning subluxation dogma and believe that cultural authority will continue to elude us so long as we assert dogma as though it were validated clinical theory."
