The objective was to compare the Bath Ankylosing Spondylitis Metrology Index (BASMI) with radiology as a measure of disease outcome. Fifty-three patients, covering the entire spectrum of disease severity, were blindly and independently assessed using the BASMI (total of five standardized measurements, scoring range 0-10) and a radiology score of the four main spinal areas affected by ankylosing spondylitis (AS). BASMI correlates positively with the total radiology score (r = 0.74), while the individual BASMI scores for cervical rotation (r = 0.59), wall to tragus (r = 0.61), lumbar side flexion (r = 0.56), lumbar flexion (r = 0.68) and intermalleolar distance (r = 0.50) correlate positively with their respective radiology scores. BASMI and radiology do not relate well to each other as BASMI takes account of normal physical limitation and soft tissue involvement. In addition, although radiology scores are termed a 'gold standard', they are unreliable. Therefore, BASMI may be judged to be more important in assessing AS and become a 'gold standard' itself.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
