The University of Wisconsin Running Injury and Recovery Index (UWRI) is the first running-specific patient-reported outcome measure (PROM). The UWRI evaluates the key elements runners use to self-assess running ability during recovery. This study evaluated the construct-related validity and responsiveness of the UWRI as an evaluative PROM of running ability following running-related injury (RRI).
Prospective longitudinal study.
Runners seeking care from a physical therapist for an RRI (n = 396) completed PROMs at baseline and 12 weeks later. Change in UWRI score was validated against the global rating of change (GROC), Veterans RAND 12-Item Health Survey (VR-12) change, and change in body region- specific PROMs. Responsiveness was evaluated using anchor-based and distribution-based techniques.
Change in UWRI score (mean ± SD, 7.7 ± 8.9 points) was correlated with the GROC ( = 0.67), as well as with changes in the VR-12 Physical Component Summary (PCS) ( = 0.54) and Mental Component Summary (MCS) ( = 0.31). Change in UWRI score was correlated with changes in the Foot and Ankle Ability Measure sports subscale ( = 0.75), the 12-item International Hip Outcome Tool ( = 0.75), and the Anterior Knee Pain Scale ( = 0.48), but not with the Oswestry Disability Index Version 2.0 ( = 0.05). Change in UWRI score was significantly different in runners reporting significant improvement (12.2 ± 5.9 points), slight improvement (7.1 ± 6.6 points), no change (0.0 ± 9.1 points), and worsening (-14.6 ± 7.4 points) on the GROC anchor-based responsiveness assessment. The UWRI minimal important change and minimal clinically important difference were 5 and 8 points, respectively.
The UWRI is a valid clinical tool for evaluating running ability following RRI; it demonstrated longitudinal validity (GROC), convergent validity (PCS and body region- specific PROMs), divergent validity (MCS), and responsiveness to changes in patient-perceived running ability. .
威斯康星大学跑步损伤和恢复指数（UWRI）是首个专门针对跑步者的患者报告结局测量（PROM）。UWRI 评估了跑步者在恢复期间自我评估跑步能力时使用的关键要素。本研究评估了 UWRI 作为一种与跑步相关损伤（RRI）后评估跑步能力的评价性 PROM 的结构相关效度和反应度。
前瞻性纵向研究。
因 RRI 而向物理治疗师寻求治疗的跑步者（n = 396）在基线和 12 周后完成了 PROMs。UWRI 评分的变化通过与整体变化评级（GROC）、退伍军人 RAND 12 项健康调查（VR-12）变化以及特定身体区域 PROM 的变化进行验证。反应度通过基于锚定和基于分布的技术进行评估。
UWRI 评分的变化（平均值 ± 标准差，7.7 ± 8.9 分）与 GROC（ = 0.67）相关，与 VR-12 生理成分综合评分（PCS）（ = 0.54）和心理成分综合评分（MCS）（ = 0.31）的变化相关。UWRI 评分的变化与足踝能力测量运动分量表（ = 0.75）、12 项国际髋关节结果工具（ = 0.75）和前膝痛量表（ = 0.48）的变化相关，但与 Oswestry 残疾指数 2.0 版本（ = 0.05）无关。在基于 GROC 锚定反应性评估报告有显著改善（12.2 ± 5.9 分）、稍有改善（7.1 ± 6.6 分）、无变化（0.0 ± 9.1 分）和恶化（-14.6 ± 7.4 分）的跑步者中，UWRI 评分的变化有显著差异。UWRI 的最小重要变化和最小临床重要差异分别为 5 分和 8 分。
UWRI 是一种评估 RRI 后跑步能力的有效临床工具；它表现出纵向有效性（GROC）、收敛有效性（PCS 和特定身体区域的 PROMs）、发散有效性（MCS）和对患者感知跑步能力变化的反应度。
