OBJECTIVES: To examine the association between radiographic lumbosacral (LS) osteoarthritis (OA) and lumbar flexibility in elders without back pain or known spinal pathology and to develop a reliable grading system for osteoarthritis of the lumbosacral spine. DESIGN: Cross-sectional study. SETTING: Durham VA and Duke University Medical Center Department of Radiology. PARTICIPANTS: 35 volunteers aged 64-90 (nursing home residents and community dwellers). Exclusion criteria were known spinal pathology, back pain, inability to stand independently for 1 minute, and > 150% of ideal body weight. INTERVENTIONS: All subjects underwent LS spine radiographs and flexibility measures (forward flexion, extension, lateral flexion, and axial rotation). MAIN OUTCOME MEASURES: Reliability of ordinal OA X-ray grading system, tested using intraclass correlations (ICCs); stability of flexibility measures, using ICCs; and association of disc or facet summary scores (sum of all levels, T12 thru S1) with fle
