The structural validity of the Lower extremity functional scale (LEFS), the Visual analogue scale foot and ankle (VAS-FA), and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) has not been compared earlier in patients after foot and ankle surgery.
Altogether 165 previously operated patients completed the foot and ankle specific instruments, the 15D health-related quality of life (HRQoL) instrument, and general health (VAS).
The LEFS, the VAS-FA and the WOMAC had slight differences in their measurement properties. The VAS-FA had the best targeting and coverage. All three foot and ankle measures accounted for mobility and usual activities when compared to the different aspects of generic HRQoL.
The LEFS, the VAS-FA and the WOMAC have relatively similar psychometric properties among foot and ankle patients, yet the VAS-FA provides the best targeting and coverage.
下肢功能量表（LEFS）、足部和踝关节视觉模拟量表（VAS-FA）以及西安大略和麦克马斯特大学骨关节炎指数（WOMAC）的结构效度在足部和踝关节手术后患者中尚未得到早期比较。
共有 165 名先前接受过手术的患者完成了足部和踝关节特定的仪器、15D 健康相关生活质量（HRQoL）仪器和一般健康（VAS）评估。
LEFS、VAS-FA 和 WOMAC 在测量特性方面存在细微差异。VAS-FA 具有最佳的针对性和覆盖范围。与通用 HRQoL 的不同方面相比，所有三种足部和踝关节测量方法都能反映活动能力和日常活动。
LEFS、VAS-FA 和 WOMAC 在足部和踝关节患者中的心理测量特性相似，但 VAS-FA 提供了最佳的针对性和覆盖范围。
