DESIGN: Study subjects were examined by a chiropractor who was unaware of their low back pain status. Information on low back pain was then collected in a self-report questionnaire.
SETTING: Research laboratory at the Odense University Hospital (Denmark).
SUBJECTS: A subset of 166 healthy twins taken from a panel of population-generated twins born between 1953-1982.
EXAMINER: Chiropractor with approximately 10 years of clinical experience.
MAIN OUTCOME MEASURES: The prevalence of a number of lumbopelvic dysfunctional tests (4 observational, 6 pain-on-movement, and 2 pain provocation tests), and a diagnostic conclusion based on these test results were studied in relation to low back pain status.
RESULTS: There was no single test that was clinically acceptable in relation to all 5 aspects of the study. At least one pain-on-movement test was the only variable that had a totally acceptable pattern.
CONCLUSION: Although no individual test was accurate, the diagnostic discrimination on the basis of these tests was satisfactory.
