The aim of the present study is to establish the relationship between foot-ankle patient-reported outcome measures (PROM) and three measures of foot-ankle alignment (MoFAA) in patients with metatarsal head pain.
A cross-sectional study where 206 patients completed three PROMs and a clinician recorded three MoFAA bilaterally (three times each). A reliability analysis of the MoFAA, a correlation analysis (between MoFAA and PROM) and regression analysis (dependent variable: PROM; independent variables: MoFAA) were performed.
Pearson's coefficient changed in each PROM used, ranging from 0.243 (AAOS-FAM-FVA) to 0.807 (FFI-first MTPJE). Regression indices (R-corrected) ranged between 0.117 (AAOS-FAM) and 0.701 (FFI).
The MoFAA correlated between moderately to strongly with the foot-ankle PROM selected. The level of correlation between MoFAA and PROM was higher when patients with metatarsal head pain were asked about foot health status, pain and function; however, the correlation was poor when the patient was asked about shoe aspects. In addition, the MoFAA variable that achieved the highest correlation value was the first metatarsophalangeal joint extension. The results obtained in this study could be used in future studies to develop tools for assessing and monitoring patients with metatarsal head pain.
本研究旨在建立跖骨头疼痛患者足部-踝关节患者报告结局指标（PROM）与三种足部-踝关节对线测量指标（MoFAA）之间的关系。
一项横断面研究，206例患者完成三项PROM，临床医生双侧记录三项MoFAA（每项记录三次）。对MoFAA进行可靠性分析、相关性分析（MoFAA与PROM之间）以及回归分析（因变量：PROM；自变量：MoFAA）。
所使用的每项PROM中，皮尔逊系数有所不同，范围从0.243（美国矫形外科医师学会足部与踝关节功能评估量表-足部视觉模拟评分）到0.807（足部功能指数-第一跖趾关节伸展）。校正决定系数（R校正）范围在0.117（美国矫形外科医师学会足部与踝关节功能评估量表）至0.7（足部功能指数）之间。
MoFAA与所选的足部-踝关节PROM之间存在中度至高度相关性。当询问跖骨头疼痛患者足部健康状况、疼痛和功能时，MoFAA与PROM之间的相关性水平较高；然而，当询问患者鞋子相关方面时，相关性较差。此外，相关性值最高的MoFAA变量是第一跖趾关节伸展。本研究所得结果可用于未来研究，以开发评估和监测跖骨头疼痛患者的工具。
