Ten female fibromyalgia subjects (mean age = 48.4) and ten matched healthy controls (mean age = 50.6) performed a perceptual-motor video task. Surface electromyography (EMG) was recorded from three sites before, during, and after perceptual-motor task performance (active and 'passive' forearms: Surface above m. flexor carpi radialis; neck: Surface above m. trapezius, right side). Task performance provoked EMG activation at all recording sites and in both subject groups, and scores failed to distinguish between the groups. However, the quality of task performance was inferior in the fibromyalgia group. Responses to motivational state measures obtained from the experimental situation revealed no group differences. The fibromyalgia subjects reported relatively high exposure to stressors attributed to their own body (but not to work, family, and economy), and high efforts invested to cope with such stressors in everyday life. The results failed to support a role for high muscle tension and anxiety in fibromyalgia.
十名女性纤维肌痛患者（平均年龄 = 48.4岁）和十名匹配的健康对照者（平均年龄 = 50.6岁）进行了一项感知运动视频任务。在感知运动任务执行前、执行期间和执行后，从三个部位记录表面肌电图（EMG）（活动和“被动”前臂：桡侧腕屈肌表面；颈部：右侧斜方肌表面）。任务执行在所有记录部位以及两个受试者组中均引发了EMG激活，并且得分未能区分两组。然而，纤维肌痛组的任务执行质量较差。从实验情境中获得的对动机状态测量的反应未显示出组间差异。纤维肌痛患者报告称，他们相对较高地暴露于归因于自身身体的压力源（而非工作、家庭和经济方面），并且在日常生活中为应对此类压力源投入了大量精力。结果未能支持高肌肉张力和焦虑在纤维肌痛中的作用。
