Low back pain (LBP) is a common musculoskeletal problem, associated with disability and high societal costs. The Oswestry Disability Index (ODI) is among the most commonly used patient reported outcome measures to measure disability due to LBP. Evidence supporting the reliability and validity of the Nepali Version of Oswestry Disability Index (NODI) exists, but its responsiveness is yet to be assessed.
We aimed to assess the responsiveness of NODI in participants with non-specific low back pain.
The study included 102 (Male 41, Female 61) participants with non-specific low back pain, attending the physiotherapy outpatient department of a tertiary care hospital and nearby community. The NODI was administered to the patients at baseline and again 2 weeks later along with a 7-item Nepali Version of Global Rating of Change (GROC-NP). Responsiveness of NODI was assessed by plotting Receivers Operating Characteristics (ROC) curve.
The area under curve (AUC) of NODI was 0.88. The best cut-off point on the NODI for improvement on the GROC-NP or the minimal clinical important change (MIC) was 4.22 and ranged from 3.11 to 6.34. The sensitivity and specificity was 77.4% and 84.2% respectively.
NODI is a responsive scale which can discriminate between participants whose level of disability due to LBP is stable or improving. The result for minimal clinically important change, sensitivity and specificity are consistent with other cross culturally adopted versions.
腰痛（LBP）是一种常见的肌肉骨骼问题，与残疾和高昂的社会成本相关。奥斯维斯特里残疾指数（ODI）是最常用的患者报告结局指标之一，用于衡量因腰痛导致的残疾情况。支持尼泊尔语版奥斯维斯特里残疾指数（NODI）可靠性和有效性的证据已经存在，但其反应度尚未评估。
我们旨在评估NODI在非特异性腰痛患者中的反应度。
该研究纳入了102名（男性41名，女性61名）非特异性腰痛患者，他们来自一家三级医院的理疗门诊及附近社区。在基线时对患者进行NODI评估，2周后再次评估，同时使用7项尼泊尔语版总体变化评定量表（GROC-NP）。通过绘制受试者操作特征（ROC）曲线来评估NODI的反应度。
NODI的曲线下面积（AUC）为0.88。GROC-NP评定为改善或最小临床重要变化（MIC）时，NODI的最佳截断点为4.22，范围在3.11至6.34之间。敏感性和特异性分别为77.4%和84.2%。
NODI是一个有反应度的量表，能够区分因腰痛导致的残疾水平稳定或改善的参与者。最小临床重要变化、敏感性和特异性的结果与其他跨文化采用的版本一致。
