AbstractObjectivesThe goal of this study was to assess agreement on signs and symptoms of myofascial pain for chiropractors, physicians, and registered massage therapists.Methods337 healthcare practitioners participated in the survey. The questionnaire probed clinician agreement with the chosen signs and symptoms using a 7‐point agreement scale (1 = absolutely agree, 7 = absolutely disagree). Agreement was assessed using intraclass correlation within chiropractor, physician, and registered massage therapist groups and across all groups. Descriptive statistics, including mean response values, were used to assess which signs or symptoms were most often associated with myofascial pain.ResultsThere was poor agreement within chiropractors, physicians, and registered massage therapists on the criteria that represent myofascial pain syndrome. Physicians and massage therapists were in agreement on 4 items and disagreed on 2 items. Chiropractors were in agreement on a different set of signs and symptoms relative to physicians and registered massage therapists, and they expressed neutrality on most statements in the questionnaire. Registered massage therapists were in most agreement amongst each other as a group (intraclass correlation coefficient [ICC] = 0.80) relative to chiropractors (ICC = 0.59) and physicians (ICC = 0.51).DiscussionOur results suggest that there is a lack of agreement within and between healthcare practitioner groups on the signs and symptoms that define myofascial pain syndrome. We suggest the demonstrated variability in diagnostic knowledge be remedied through the establishment and universal use of official validated criteria. Future research should focus on developing criteria specific to myofascial pain syndrome. Finally, knowledge translation strategies may be implemented to increase clinician knowledge of available criteria.
