Fibromyalgia (FM), a rheumatological disorder of unknown origin, is characterized by both physical and psychological symptoms. Although inconclusive results have been reported for most treatment modalities, exercise appears to have universal support for decreasing the myriad of symptoms associated with FM. Weaknesses in the literature, however, prevent conclusive statements regarding exercise prescription and concomitant impact on FM symptomology.
The current pilot study attempted to examine the effect of a 24-wk walking program at predetermined intensities on FM.
Initial design was a randomized control trial with high- and low-intensity exercise groups, and a control group. Subsequent nonrandomized control trials were based on actual exercise behavior.
No differences between initial groups were identified. By collapsing groups, heart rate (HR) decreased (P < 0.05) weeks 0-12. Functional impairments were reduced 54% weeks 0-24, with exercise having a large impact (omega2 = 0.30) on this decrease. By reassigning groups, impact of FM on current health status decreased in the low-intensity group (P < 0.05) and increased in the high-intensity group (P < 0.02) weeks 0-24. Omega squared indicated strong influence of exercise on pain (omega2 = 0.51), with greater pain in the high-intensity group.
A larger number of subjects and direct supervision of the training program to increase compliance is necessary to clarify the effects of a walking program on the manifestations of FM. Results indicate that intensity of the walking program is an important consideration. Individuals with FM can adhere to low-intensity walking programs two to three times per week, possibly reducing FM impact on daily activities.
纤维肌痛（FM）是一种病因不明的风湿性疾病，其特征为身体和心理症状。尽管大多数治疗方式的结果尚无定论，但运动似乎在减轻与FM相关的众多症状方面得到广泛支持。然而，文献中的不足使得关于运动处方及其对FM症状学的伴随影响无法得出确凿结论。
当前的试点研究试图检验一项为期24周、按预定强度进行的步行计划对FM的影响。
最初的设计是一项随机对照试验，包括高强度和低强度运动组以及一个对照组。后续的非随机对照试验基于实际运动行为。
最初的几组之间未发现差异。通过合并组，心率（HR）在第0至12周下降（P < 0.05）。在第0至24周，功能障碍减少了54%，运动对此减少有很大影响（ω² = 0.30）。通过重新分组，在第0至24周，FM对当前健康状况的影响在低强度组下降（P < 0.05），在高强度组增加（P < 0.02）。ω²表明运动对疼痛有强烈影响（ω² = 0.51），高强度组疼痛更严重。
需要更多的受试者以及对训练计划进行直接监督以提高依从性，才能阐明步行计划对FM表现的影响。结果表明步行计划的强度是一个重要考虑因素。FM患者可以每周坚持进行两到三次低强度步行计划，这可能会减轻FM对日常活动的影响。
