Abstract

Introduction: Fibromyalgia involves chronic pain and disrupted physical activity and sleep. Research examining the relationship between pre-bedtime physical activity, pain, and objective sleep is limited. This study examined whether objectively measured physical activity levels (via actigraphy), pain intensity, or their interaction are associated with polysomnographic sleep outcomes.

Methods: Adults with fibromyalgia and insomnia complaints (n = 134, mean age = 52 yrs, SD = 12 yrs, 94% female) completed 14 days of biaxial, wrist worn actigraphy, pain ratings, and a single night of polysomnography (PSG). Average activity for intervals 9:00-12:00, 12:00-15:00, 15:00-18:00, 18:00-21:00 was computed. Multiple regressions examined whether average activity, average evening pain, or their interaction were associated with PSG outcomes: sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency, %stage1, %stage2, %stage3, and %rapid eye movement. Analyses controlled for age, body mass index, average bedtime, time in bed, and sleep/pain medication use.

Results: Greater morning actigraphic physical activity from 9:00 to 12:00 was independently associated with greater %stage 1 sleep (B = 0.01, SE = 0.00, p < .01). Greater afternoon activity from 12:00 to 15:00 independently predicted a higher WASO (p < .001). Associations between afternoon physical activity from 12:00 to 15:00 and greater %stage 1 (p < .001) were significant for at higher (~71/100), average (~52/100), but not lowest (~32/100) pain.

Conclusion: Greater morning and afternoon activity is associated with greater PSG sleep fragmentation and greater %stage 1 sleep in individuals with fibromyalgia and insomnia complaints, and the relationship between higher physical activity and greater %stage 1 is stronger for individuals with higher pain. Further studies examining causal pathways between physical activity, activity pacing, and sleep are warranted in fibromyalgia.

纤维肌痛患者的活动图、疼痛强度和多导睡眠图睡眠。

简介:纤维肌痛包括慢性疼痛和身体活动和睡眠中断。关于睡前身体活动、疼痛和客观睡眠之间关系的研究是有限的。这项研究考察了客观测量的身体活动水平(通过活动记录仪)、疼痛强度或它们之间的相互作用是否与多导睡眠图睡眠结果有关。方法:患有纤维肌痛和失眠的成年人(n = 134，平均年龄= 52岁，SD = 12岁，94%为女性)完成了14天的双轴、腕带活动描画、疼痛评分和一晚的多导睡眠描画(PSG)。计算9:00-12:00、12:00-15:00、15:00-18:00、18:00-21:00时段的平均活动量。多重回归检验了平均活动、平均夜间疼痛或它们的相互作用是否与PSG结果相关:睡眠发作潜伏期(SOL)、睡眠发作后醒来(WASO)、睡眠效率、第一阶段、第二阶段、第三阶段和快速眼动。分析控制了年龄、体重指数、平均就寝时间、卧床时间和睡眠/止痛药使用情况。结果:上午9:00 - 12:00较大的体力活动与较大的% 1阶段睡眠独立相关(B = 0.01, SE = 0.00, p)。结论:在纤维肌痛和失眠患者中，较大的上午和下午体力活动与较大的PSG睡眠碎片和较大的% 1阶段睡眠相关，而在疼痛程度较高的个体中，体力活动与较大的% 1阶段睡眠之间的关系更强。在纤维肌痛中，进一步研究身体活动、活动起搏和睡眠之间的因果关系是必要的。

期刊介绍： Behavioral Sleep Medicine addresses behavioral dimensions of normal and abnormal sleep mechanisms and the prevention, assessment, and treatment of sleep disorders and associated behavioral and emotional problems. Standards for interventions acceptable to this journal are guided by established principles of behavior change. Intending to serve as the intellectual home for the application of behavioral/cognitive science to the study of normal and disordered sleep, the journal paints a broad stroke across the behavioral sleep medicine landscape. Its content includes scholarly investigation of such areas as normal sleep experience, insomnia, the relation of daytime functioning to sleep, parasomnias, circadian rhythm disorders, treatment adherence, pediatrics, and geriatrics. Multidisciplinary approaches are particularly welcome. The journal’ domain encompasses human basic, applied, and clinical outcome research. Behavioral Sleep Medicine also embraces methodological diversity, spanning innovative case studies, quasi-experimentation, randomized trials, epidemiology, and critical reviews.
