为了研究纤维肌痛（FM）患者的表面肌电图（SEMG）反应，已经进行了几项研究。一些研究未能证明FM患者和健康个体之间的差异，而另一些研究则发现了SEMG参数的差异。FM患者的肌电分析区域不同，由于SEMG技术的应用方式不同，也产生了肌电的异质性。本研究的目的是评估肌肉的修改，表面肌电分析FM妇女相对于健康对照组的样本，并调查表面肌电参数和疾病的临床方面之间的关系。本文记录了100例女性FM患者（48.10 ± 11.96岁）和50例健康女性（48.60 ± 11.18岁）等长收缩时胫前肌和股内侧肌远端的表面肌电（SEMG）。计算SEMG信号的中值频谱频率（SEP）和传导速度（CV）的初始值和变化率。对临床指标纤维肌痛影响问卷、疼痛、压痛点、疲劳等进行评价，并与表面肌电结果进行相关性分析。对于统计分析，使用Mann-Whitney检验、卡方检验和斯皮尔曼相关性。绝对值和所谓的疲劳指数（FI）显著低于（p < 0.001）FM患者研究的两块肌肉（电压：93.2 μV; FI：1.10，0.89）相对于健康对照FM患者与对照组相比，在FM患者和对照组中观察到了更小的百分比值降低（22% vs 38%）。SEMG参数的归一化中值频率（MNF）（%）的下降与FM的严重程度（用压痛点评估）之间存在显著相关性。我们已经发现FM患者相对于健康对照组的一些有趣的肌肉改变，关于导致FM显著较低的BMI、CV和FI值。患者可能有不同的纤维募集或可能的II型纤维萎缩，表明他们无法达到肌肉松弛。
Several studies have been carried out in order to investigate surface electromyography (SEMG) response on fibromyalgic (FM) patients. Some studies failed to demonstrate differences between FM patients and healthy individuals while others found differences in SEMG parameters. Different muscular region have been analyzed in FM patients and heterogeneity is also produced because of the different ways in which the SEMG technique is used. The aims of this study were to evaluate muscle modifications by SEMG analysis in FM women with respect to a sample of healthy controls and to investigate the relationships between SEMG parameters and the clinical aspects of the disease. SEMG was recorded in 100 FM women (48.10 ± 11.96 yr) and in 50 healthy women (48.60 ± 11.18 yr), from the tibialis anterior and the distal part of vastus medialis muscle during isometric contraction. Initial values and rate of change of median spectral frequency (MDF) and conduction velocity (CV) of the SEMG signal were calculated. The clinical parameters "Fibromyalgia Impact Questionnaire", pain, tender points, tiredness were evaluated and the relationships between these data and the SEMG results were also studied. For the statistical analysis Mann-Whitney test, chi-square test and Spearman correlation were used. MDF absolute values and the so-called Fatigue Index (FI) were significantly lower (p < 0.001) in both muscles studied in FM patients (MDF: 93.2 μV; FI: 1.10, 0.89) with respect to healthy controls (MDF: 138.2 μV; FI: 2.41, 1.66) and a smaller reduction in the percentage values of MDF was observed in FM patients vs controls (22% vs 38%). A significant correlation was found between the SEMG parameter decrement of normalized median frequency (MNF) (%) and seriousness of FM (evaluated by means of tender points). We have found some interesting muscle modifications in FM patients with respect to healthy controls, regarding MDF, CV and FI values which resulted significantly lower in FM. Patients might have a different fiber recruitment or a possible atrophy of type II fibers suggesting that they are not able to reach muscle relaxation.
