To evaluate the effectiveness and tolerability of two pool-based physical therapies, stretching and Ai Chi, in fibromyalgia symptomatology and sleep quality.
Eighty-one patients, randomly assigned to stretching (n=39) or Ai Chi (n=42), received 18 physiotherapy sessions and were evaluated at baseline, at treatment termination, and after 4 and 12 weeks of follow-up. Main outcome measures were the Fibromyalgia Impact Questionnaire (FIQ) and the Pittsburgh Sleep Quality Index (PSQI). Secondary outcome measures included the Beck Depression Inventory (BDI), the State and Trait Anxiety Inventory (STAI), and the SF-12 Health Survey (SF-12). Data analysis was done with repeated measures ANOVA and effect size estimation.
No differences were found between groups but significant reduction in the FIQ and the PSQI scores were observed in Ai Chi but not in stretching group, with larger effect sizes and longer effect duration on sleep measures. BDI scores decreased in stretching but not in Ai Chi group with small effect sizes. Trait-anxiety scores decreased in both groups also with small effect sizes. The mental component summary of the SF-12 increased only in stretching group with effect sizes moderate to large.
Although no global differences were found between groups, Ai Chi significantly improved fibromyalgia symptomatology and sleep quality, whereas stretching only improved subjects' psychological well-being.
评估两种基于泳池的物理疗法（拉伸和八段锦）对纤维肌痛症状和睡眠质量的有效性和耐受性。
81 名患者随机分配至拉伸组（n=39）或八段锦组（n=42），接受 18 次物理治疗，分别在基线、治疗结束时以及随访 4 周和 12 周时进行评估。主要结局指标为纤维肌痛影响问卷（FIQ）和匹兹堡睡眠质量指数（PSQI）。次要结局指标包括贝克抑郁量表（BDI）、状态-特质焦虑量表（STAI）和健康调查简表 12 项（SF-12）。数据分析采用重复测量方差分析和效应量估计。
两组间无差异，但八段锦组的 FIQ 和 PSQI 评分显著降低，而拉伸组无此变化，睡眠指标的效应量更大，持续时间更长。拉伸组的 BDI 评分降低，但八段锦组无此变化，效应量较小。两组的特质焦虑评分均降低，效应量也较小。SF-12 的心理成分综合评分仅在拉伸组增加，效应量为中到大。
尽管两组间无总体差异，但八段锦显著改善了纤维肌痛症状和睡眠质量，而拉伸仅改善了受试者的心理健康。
