OBJECTIVES: The study objectives were to establish ojeok-san (Five Accumulation Powder: wu ji san) administration criteria and a questionnaire to evaluate the holistic effects of ojeok-san on patients with low back pain (LBP). METHODS: Texts and literatures, recommended by specialists, were searched to gather ojeok-san-related symptoms. Then, the opinions of Oriental medicine doctors (OMDs) practicing in Seoul were surveyed to ask which symptoms they consider the most in clinical practice. Based on the survey, selection of potential items for the questionnaire was made. The final version was established based on the results of the survey and Delphi process of musculoskeletal diseases specialists. In order to evaluate the reliability and validity of the newly developed assessment tool (Ojeok-san Low Back Questionnaire: OLQ), patients with chronic LBP were recruited. OLQ and other tools such as visual analogue scale, numeric rating scale, Roland-Morris Disability Questionnaire, Modified-Modified Schober test, and 36-Item Short Form Health Survey were applied to the subjects in a 2-week interval. Test-retest reliability, internal consistency, and convergent and discrimination validity were assessed. RESULTS: A total of 90 potential items were generated by the research team. One hundred and two (102) OMDs fully replied to the survey. Based on the survey results, 34 items were initially selected as potential items. Through Delphi method of experts, 10 top items, rated more than 5 points on a scale of 10, were finally established. The 10 items were each established as a response scale of 0-10 (0 as no symptom and 10 as the most excessive form of symptom). Based on the above stages, an initial OLQ was established and used in the evaluation phase. The validity and reliability of OLQ assessment results showed high test-retest reliability, intraclass correlation coefficient, and internal consistency. CONCLUSIONS: The newly developed Ojeok-san administration criteria and questionnaire may be a promising tool for future Oriental medicine clinical study protocols.
