To evaluate and compare responsiveness characteristics for the Foot Function Index revised short form (FFI-RS), RAND-12 Health Status Inventory (RAND-12), and Numeric Rating Scale (NRS), in patients with plantar fasciopathy receiving non-surgical treatment.
This study was conducted on a sub-group of patients from an ongoing randomised controlled trial. One-hundred fifteen patients were included. The patient-reported outcome measures (PROMs) were applied at baseline and after 6 months. Responsiveness was calculated using standardised response mean and area under the receiver operating characteristic (ROC) curve. ROC curves were used to compute the minimal important change (MIC) for the outcome measures.
The region specific FFI-RS had best responsiveness and the NRS at rest had lowest responsiveness.
FFI-RS were marginally more responsive than the other PROMs. Responsiveness and MIC estimates should be regarded as indicative rather than fixed estimates.
评估和比较足底筋膜炎接受非手术治疗患者的足部功能指数修订短表（FFI-RS）、RAND-12 健康状况量表（RAND-12）和数字评分量表（NRS）的反应特征。
本研究是对正在进行的随机对照试验的亚组患者进行的。共纳入 115 例患者。在基线和 6 个月后应用患者报告的结局测量（PROM）。使用标准化反应均值和受试者工作特征（ROC）曲线下面积来计算反应性。ROC 曲线用于计算结局测量的最小重要变化（MIC）。
区域特异性 FFI-RS 的反应性最好，而静息时的 NRS 反应性最差。
FFI-RS 比其他 PROM 更具反应性。反应性和 MIC 估计值应被视为指示性而非固定估计值。
