The present study aimed (1) to assess the validity and reliability of the Borg category-ratio (CR-10) scale for monitoring exercise intensity in women with fibromyalgia (FM) and (2) to examine whether women with FM can discriminate between perceived exertion and exercise-induced pain. Thirty-three women with FM performed two incremental treadmill tests (1 week separated). Heart rate, oxygen uptake, minute ventilation and respiratory quotient were measured. The ratings of perceived exertion (RPE: CR-10 scale) and exercise-induced pain were obtained at each workload. The Spearman's correlation of RPE with the physiological responses ranged from 0.69 to 0.79. The regression models explained ~50% of the variability of the studied physiological responses. We found "perfect acceptable" agreement in 69% of the observations. Weighted Kappa was 0.66 (95% confidence interval [CI]: 0.59-0.72). There were differences between RPE and pain at workloads 3 (1.50; 95% CI: 0.85-2.16), 4 (2.10; 95% CI: 1.23-2.96), 5 (3.40; 95% CI: 1.29-5.51) and 6 (3.97; 95% CI: 1.61-6.33). The main findings of the present study suggest that the Borg CR-10 scale is valid and moderately reliable for monitoring exercise intensity in women with FM, and these patients were able to discriminate between exertion and exercise-induced pain.
（1）评估博格类别比率（CR-10）量表在监测纤维肌痛（FM）女性运动强度方面的有效性和可靠性；（2）检查FM女性是否能够区分感知到的用力程度和运动诱发的疼痛。33名FM女性进行了两次递增式跑步机测试（间隔1周）。测量了心率、摄氧量、分钟通气量和呼吸商。在每个工作负荷下获取感知用力程度评分（RPE：CR-10量表）和运动诱发的疼痛评分。RPE与生理反应的斯皮尔曼相关性在0.69至0.79之间。回归模型解释了所研究生理反应变异性的约50%。我们在69%的观察结果中发现了“完全可接受”的一致性。加权Kappa为0.66（95%置信区间[CI]：0.59 - 0.72）。在工作负荷3（1.50；95%CI：0.85 - 2.16）、4（2.10；95%CI：1.23 - 2.96）、5（3.40；95%CI：1.29 - 5.51）和6（3.97；95%CI：1.61 - 6.33）时，RPE和疼痛之间存在差异。本研究的主要发现表明，博格CR-10量表在监测FM女性运动强度方面是有效的且具有中等可靠性，并且这些患者能够区分用力程度和运动诱发的疼痛。
