Abstract

Objectives: The aim of the study was to evaluate foot posture and the mechanical properties of extrinsic foot muscles in fibromyalgia.

Methods: Patients with fibromyalgia (n = 86) and age- and gender-matched controls (n = 41) were included in the study. Foot Posture Index (FPI), Beighton and Brighton criteria were used to evaluate static foot posture, joint hypermobility, and benign joint hypermobility syndrome (BJHS), respectively. Tonus, elasticity, and stiffness of the extrinsic foot muscles including gastrocnemius medialis, tibialis anterior, and peroneus longus were measured by the MyotonPRO^® device. Foot function, quality of life, and physical activity level were assessed by the Foot Function Index (FFI), Short Form-36 (SF-36), and the International Physical Activity Questionnaire-Short Form (IPAQ-SF), respectively.

Results: The frequency of abnormal foot posture in the fibromyalgia and control groups was 68.6% versus 39%, respectively; and neutral foot posture was approximately twice as prevalent in the control group compared to the fibromyalgia group (p = 0.006). Pronated foot posture was the most common abnormality in fibromyalgia (61.6%) and observed in 85.5% of the patients with joint hypermobility and in 87.1% of those meeting BJHS criteria. The elasticity of peroneus longus at rest and the elasticity of tibialis anterior in the standing position were significantly different between the fibromyalgia group and the control group [1.08 (0.22) vs. 1.02 (0.25), p = 0.037 and 0.92 (0.29) vs. 0.87 (0.24), p = 0.011, respectively]. Regarding the fibromyalgia group, no difference was detected among foot posture groups in terms of myotonometric data.

Conclusions: Pronation foot posture is common in fibromyalgia with a much higher frequency in fibromyalgia patients with hypermobility. In daily clinical practice for fibromyalgia, particular attention should be given to foot alignment.

揭示纤维肌痛的足外肌机械特性和足部姿势的改变：一项病例对照研究。

研究目的研究旨在评估纤维肌痛患者的足部姿势和足部外侧肌肉的机械特性：研究对象包括纤维肌痛患者（86 人）以及年龄和性别匹配的对照组（41 人）。足部姿势指数（FPI）、Beighton 和 Brighton 标准分别用于评估静态足部姿势、关节过度活动和良性关节过度活动综合征（BJHS）。通过 MyotonPRO® 设备测量足部外侧肌肉（包括腓肠肌内侧、胫骨前肌和腓骨长肌）的张力、弹性和僵硬度。足部功能、生活质量和体力活动水平分别通过足部功能指数（FFI）、短表-36（SF-36）和国际体力活动问卷-短表（IPAQ-SF）进行评估：结果：纤维肌痛组和对照组的足部姿势异常发生率分别为 68.6% 和 39%；对照组的中性足部姿势发生率约为纤维肌痛组的两倍（p = 0.006）。前倾的足部姿势是纤维肌痛中最常见的异常（61.6%），85.5%的关节活动过度患者和 87.1%的符合 BJHS 标准的患者都出现了前倾的足部姿势。纤维肌痛组和对照组的腓骨长肌静止时的弹性和胫骨前肌站立时的弹性有显著差异[分别为 1.08 (0.22) vs. 1.02 (0.25)，p = 0.037 和 0.92 (0.29) vs. 0.87 (0.24)，p = 0.011]。在纤维肌痛组中，各足部姿势组之间的肌张力数据没有差异：结论：前倾的足部姿势在纤维肌痛中很常见，而在活动过度的纤维肌痛患者中出现的频率更高。在纤维肌痛的日常临床实践中，应特别注意足部对齐。

期刊介绍： RHEUMATOLOGY INTERNATIONAL is an independent journal reflecting world-wide progress in the research, diagnosis and treatment of the various rheumatic diseases. It is designed to serve researchers and clinicians in the field of rheumatology. RHEUMATOLOGY INTERNATIONAL will cover all modern trends in clinical research as well as in the management of rheumatic diseases. Special emphasis will be given to public health issues related to rheumatic diseases, applying rheumatology research to clinical practice, epidemiology of rheumatic diseases, diagnostic tests for rheumatic diseases, patient reported outcomes (PROs) in rheumatology and evidence on education of rheumatology. Contributions to these topics will appear in the form of original publications, short communications, editorials, and reviews. "Letters to the editor" will be welcome as an enhancement to discussion. Basic science research, including in vitro or animal studies, is discouraged to submit, as we will only review studies on humans with an epidemological or clinical perspective. Case reports without a proper review of the literatura (Case-based Reviews) will not be published. Every effort will be made to ensure speed of publication while maintaining a high standard of contents and production. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
