Since this rule was last reviewed in May 2012, it has been amended three times. The Division received one written comment, dated 10/29/2014, from Utah Chiropractic Physician Association Executive Director Tim Apgood in which the association opposed proposed amendments regarding the definition of "ortho-bionomy". As a result of the written comment and additional public comments offered during a 11/18/2014 rule hearing, the Division and Chiropractic Physician Licensing Board recommended additional changes, and a change in proposed rule (CPR) filing was filed on 02/23/2015 and made effective on 04/21/2015. The CPR filing deleted the definition of "ortho-bionomy" from this rule.
