Abstract：
BACKGROUND: The aim of study is to examine the factors that may influence pain, disability and the limitation of activity due to the presence of fibromyalgia in the foot.
METHODS: 323 patients diagnosed with fibromyalgia were recruited. Each participant completed the Foot Function Index questionnaire (FFI) and the Revised Fibromyalgia Impact Questionnaire (FIQR). A multivariate analysis was performed to determine the factors associated with high scores in each of these questionnaires.
RESULTS: In both questionnaires, the subscales presenting the highest scores were foot pain (FFI score: 71.18 ± 20.40) and symptom intensity (FIQR score: 36.23 ± 8.04). According to the multivariate analysis, foot function is influenced by age (p = <0.001), BMI (p = 0.001), lack of physical activity (p = <0.001), the presence of rheumatoid arthritis (p = 0.012), retirement due to disability (p = <0.001) and being unemployed (p < 0.001).
CONCLUSIONS: Fibromyalgia affects foot function, provoking significant pain. Related factors include age, BMI, lack of physical activity, the presence of rheumatoid arthritis, and employment status.

摘要：
背景：研究的目的是检查可能影响疼痛的因素，由于足部纤维肌痛的存在而导致的残疾和活动限制。
方法：招募了323名诊断为纤维肌痛的患者。每位参与者完成了足功能指数问卷（FFI）和修订的纤维肌痛影响问卷（FIQR）。进行多变量分析以确定与这些问卷中的高分相关的因素。
结果：在两份问卷中，得分最高的分量表是足部疼痛(FFI评分:71.18±20.40)和症状强度(FIQR评分:36.23±8.04).根据多变量分析，足部功能受年龄影响（p=<0.001），BMI（p=0.001），缺乏体力活动（p=<0.001），类风湿关节炎的存在（p=0.012），由于残疾（p=<0.001）和失业（p<0.001）而退休。
结论：纤维肌痛影响足部功能，引起巨大的痛苦。相关因素包括年龄、BMI,缺乏体力活动,类风湿关节炎的存在，和就业状况。
