OBJECTIVES

to establish a relationship between widespread pain subjectively perceived and threshold pain tolerance on tender points, and to determine whether there are differences in threshold pain tolerance on tender points between the upper and lower body, as well as between the dominant and non-dominant side, and whether these differences have an impact on the daily life of Portuguese women with fibromyalgia (FM).

MATERIAL & METHODS: thirty-one women with FM aged between 34 and 67 years volunteered for the study. Threshold pain tolerance was assessed at critical points using a digital algometer pressure; the widespread pain index (WPI) was constructed by the addition of 19 painful body regions; and the impact on the daily life assessed by the Portuguese version of the Fibromyalgia Impact Questionnaire (FIQ), with individual interviews.

RESULTS

significant differences between the percentage of threshold pain tolerance of the whole body and the scales of widespread pain subjectively perceived were observed, showing that the widespread pain subjectively perceived by patients was between +25.9% and +27.5%. Also, significant differences between threshold pain tolerance of tender points located on the upper and lower body (1.9 ± 0.5 kg/cm2 vs. 2.6 ± 0.7 kg/cm2; respectively) were observed. However, no significant differences were found between threshold pain tolerance of tender points located on dominant and non-dominant sides (2.1 ± 0.5 kg/cm2 e 2.1 ± 0.6 kg/cm2; respectively). Additionally, the analysis showed significant correlations between pain and patient`s daily life in: FIQ total score, physical function, feel good, job ability and fatigue.

CONCLUSIONS

the women with FM show higher widespread pain subjectively perceived than threshold pain tolerance on tender points. Furthermore, the pain suffered by the patients with FM, especially that located on the upper body, either on the dominant or on the non-dominant side, has a negative influence on physical function, job ability, fatigue and feel good, affecting daily life.

目的

建立主观感受到的广泛疼痛与压痛点疼痛耐受阈值之间的关系，并确定上半身和下半身之间、优势侧和非优势侧之间压痛点的疼痛耐受阈值是否存在差异，以及这些差异是否对患有纤维肌痛（FM）的葡萄牙女性的日常生活产生影响。

材料与方法

31名年龄在34至67岁之间的FM女性自愿参与本研究。使用数字式痛觉计压力评估临界点的疼痛耐受阈值；通过将19个疼痛身体区域相加构建广泛疼痛指数（WPI）；并通过葡萄牙语版纤维肌痛影响问卷（FIQ）进行个人访谈来评估对日常生活的影响。

结果

观察到全身疼痛耐受阈值百分比与主观感受到的广泛疼痛量表之间存在显著差异，表明患者主观感受到的广泛疼痛在+25.9%至+27.5%之间。此外，观察到上半身和下半身压痛点的疼痛耐受阈值之间存在显著差异（分别为1.9±0.5kg/cm²和2.6±0.7kg/cm²）。然而，优势侧和非优势侧压痛点的疼痛耐受阈值之间未发现显著差异（分别为2.1±0.5kg/cm²和2.1±0.6kg/cm²）。此外，分析显示疼痛与患者日常生活在以下方面存在显著相关性：FIQ总分、身体功能、感觉良好、工作能力和疲劳。
