Fibromyalgia (FM) is a chronic pain syndrome, characterised by several symptoms. One of the most prevalent symptoms in FM is balance impairment that compromise the autonomy, function and performance status of patients.

Purpose: The main objective of the present study was to evaluate the effect of sensory stimulation provided by the use of a low additional thickness of 0.8 mm placed under the great toes bilaterally on the centre of pressure (CoP) measures in patients with FM. It was hypothesised that postural ability would change with a low focal additional thickness used to compute these measures.

Materials and Method: Twenty-four patients with FM voluntarily participated in this study. Postural performance during quiet standing was investigated through the CoP displacements recorded using a force-plate. Sensory stimulation was provided by a small additional thickness of 0.8 mm placed under the great toe bilaterally and two conditions were compared: additional thickness 0 (control) and 0.8 mm.

Results: An improvement of body balance through spatial parameters with sensory cutaneous stimulation applied under the great toe bilaterally were observed in patients with FM. Our results showed a significant decrease of surface area and mean speed of CoP, associated to a significant decrease of variance of speed. An additional observation is that sagittal (Y) mean position of the CoP gets more anterior (+ 5 mm) relative to control condition.

Conclusion: These findings brings new clinical perspectives in the development of intervention strategies in the management of patients with FM and balance disorders, completing validated therapeutic strategies.

大脚趾下感觉刺激对纤维肌痛患者姿势能力的影响。

纤维肌痛 (FM) 是一种慢性疼痛综合征,具有多种症状。FM 中最普遍的症状之一是平衡障碍,这会损害患者的自主性、功能和表现状态。

目的:本研究的主要目的是评估在 FM 患者的压力中心 (CoP) 措施上,在双侧大脚趾下放置 0.8 毫米的低附加厚度所提供的感觉刺激的效果。假设姿势能力会随着用于计算这些测量的低焦点附加厚度而改变。

材料和方法: 24 名 FM 患者自愿参加了这项研究。通过使用测力板记录的 CoP 位移来研究安静站立期间的姿势表现。感觉刺激是通过放置在双侧大脚趾下的 0.8 毫米的小附加厚度提供的,并比较了两种情况:附加厚度 0(对照)和 0.8 毫米。

结果:在 FM 患者中观察到通过双侧大脚趾下的感觉皮肤刺激通过空间参数改善身体平衡。我们的结果显示 CoP 的表面积和平均速度显着降低,这与速度方差的显着降低有关。另一个观察结果是,相对于对照条件,CoP 的矢状 (Y) 平均位置变得更靠前 (+ 5 mm)。

结论:这些发现为制定治疗 FM 和平衡障碍患者的干预策略提供了新的临床视角,完成了经过验证的治疗策略。
