摘要: Abstract Persistent low back pain (LBP) is one of the most common and challenging persistent conditions in older adults. Medical comorbidity also these individuals, but its impact on disability has not been examined. The purpose this study was, using a cross-sectional design, to examine functional pain-related general medical 100 community dwelling adults (mean age 74.3) with mechanical LBP. Subjects received structured history physical examination, lumbosacral spine X-rays, standardized tests function. Pain-related variables included intensity, duration, extent, lumbar motion-induced pain. General age, comorbidity, number medications, depressive symptoms, range motion, body mass index, severity radiographic pathology. Function/disability measures self-reported disability, gait speed, mean static lifts amount work performed during dynamic lifting task. Structural equation modeling was used evaluate influence function/disability. overall regression model indicated were significantly associated function/disability (R2=0.45, P
