This study aims to investigate the responsiveness and the minimum important change of the Italian version of the Oswestry Disability Index (ODI-I) in subjects with symptomatic specific low back pain associated with lumbar spondylolisthesis (SPL).
One hundred and fifty-one patients with symptomatic SPL completed the ODI-I, a 0-100 numerical rating scale (NRS), and performed the prone and supine bridge tests. The global perception of effectiveness was measured with a 7-point Likert scale. Responsiveness was assessed by distribution methods (minimum detectable change [MDC], effect size [ES], standardized response mean [SRM]) and anchor-based methods (ROC curves).
The MDC was 4.23, the ES was 0.95 and the SRM was 1.25. ROC analysis revealed an area under the curve of 0.76 indicating moderate discriminating capacity. The best cut-off point for the dichotomous outcome was 7.5 (sensitivity 90.3%, specificity 56.7%). .
The ODI-I proved to be responsive in detecting changes after conservative treatment in subjects with lumbar SPL.

本研究旨在调查意大利版奥斯维斯特里功能障碍指数（ODI-I）在有症状的与腰椎滑脱（SPL）相关的特定下腰痛患者中的反应性和最小重要变化。
151例有症状的SPL患者完成了ODI-I、0-100数字评分量表（NRS），并进行了俯卧位和仰卧位搭桥试验。用7点李克特量表测量总体疗效感知。通过分布方法（最小可检测变化[MDC]、效应量[ES]、标准化反应均值[SRM]）和基于锚定的方法（ROC曲线）评估反应性。
MDC为4.23，ES为0.95，SRM为1.25。ROC分析显示曲线下面积为0.76，表明具有中等区分能力。二分结果的最佳截断点为7.5（敏感性90.3%，特异性56.7%）。
ODI-I被证明在检测腰椎SPL患者保守治疗后的变化方面具有反应性。
