持续性腰痛 (LBP) 是老年人最常见且最具挑战性的持续性疼痛病症之一。医疗合并症在这些人中也很常见，但其对残疾的影响尚未得到研究。本研究的目的是采用横断面设计，检查疼痛相关和一般医疗合并症对 100 名患有持续性机械性腰痛的社区居住老年人（平均年龄 74.3 岁）的功能影响。受试者接受了结构化的病史和体格检查、腰骶椎 X 光检查以及身体功能的标准化测试。疼痛相关变量包括强度、持续时间、程度和腰部运动引起的疼痛。一般医学变量包括年龄、合并症、药物数量、抑郁症状、背部运动范围、体重指数和放射学病理学的严重程度。功能/残疾测量包括自我报告的残疾、步态速度、平均静态举重次数和动态举重任务期间执行的工作量。使用结构方程模型来评估疼痛和医疗变量对功能/残疾的影响。总体回归模型表明疼痛和医疗变量与功能/残疾测量显着相关（R-2 =0.45，P
Persistent low back pain (LBP) is one of the most common and challenging persistent pain conditions in older adults. Medical comorbidity also is common in these individuals, but its impact on disability has not been examined. The purpose of this study was, using a cross-sectional design, to examine the functional impact of pain-related and general medical comorbidity on 100 community dwelling older adults (mean age 74.3) with persistent mechanical LBP. Subjects received a structured history and physical examination, lumbosacral spine X-rays, and standardized tests of physical function. Pain-related variables included intensity, duration, extent, and lumbar motion-induced pain. General medical variables included age, comorbidity, number of medications, depressive symptoms, back range of motion, body mass index, and severity of radiographic pathology. Function/disability measures included self-reported disability, gait speed, and mean number of static lifts and amount of work performed during a dynamic lifting task. Structural equation modeling was used to evaluate the influence of pain and medical variables on function/disability. The overall regression model indicated pain and medical variables were significantly associated with function/disability measures (R-2 =0.45, P
