Abstract：
OBJECTIVE: This single-blind, randomized controlled study aimed to determine the effect of progressive muscle relaxation exercises on sleep quality and fatigue in the postmenopausal period. Progressive muscle relaxation aims to relax the muscles in the body and includes breathing techniques.
METHODS: This study was carried out between January 2022 and July 2022 with 63 postmenopausal women who applied to a district state hospital and had poor sleep quality. The women assigned to the experimental group (EG) (n = 31) applied progressive muscle relaxation exercises every day for 8 weeks. In contrast, the women in the control group (CG) (n = 32) continued their routine coping habits related to sleep problems and fatigue in the postmenopausal period. The EG and CG were reevaluated using the Piper Fatigue Scale and the Pittsburg Sleep Quality Index in the fourth and eighth weeks. The women applied progressive muscle relaxation exercises with a guide prepared by the researchers and the compact disc of the Turkish Psychologists Association. In the data analysis, the independent-samples t test, Fisher\'s exact test, and χ2 test were used to compare individual, obstetric, and medical characteristics between the groups. The difference between dependent groups at different times was evaluated by repeated-measures analysis of variance.
RESULTS: There was an improvement in fatigue symptoms in the progressive muscle relaxation exercises-performing EG at the end of 8 weeks compared with the CG, and fatigue symptoms increased in the CG (P < 0.001). There was a greater improvement in the sleep quality of the progressive muscle relaxation exercises-performing EG at the end of 8 weeks compared with the CG (P < 0.001).
CONCLUSIONS: In our study, it was determined that progressive muscle relaxation exercises had an improving effect on sleep quality and fatigue.

摘要：
目标：这种单盲，随机对照研究旨在确定渐进性肌肉放松锻炼对绝经后睡眠质量和疲劳的影响。渐进式肌肉放松旨在放松体内的肌肉，包括呼吸技术。
方法：这项研究于2022年1月至2022年7月进行，对63名绝经后妇女进行了研究，这些妇女在地区州立医院就诊，睡眠质量较差。被分配到实验组(EG)的妇女(n=31)每天进行渐进性肌肉放松锻炼,持续8周。相比之下,对照组（CG）的妇女（n=32）在绝经后继续其与睡眠问题和疲劳有关的常规应对习惯。在第四和第八周使用Piper疲劳量表和匹兹堡睡眠质量指数重新评估EG和CG。这些妇女使用研究人员准备的指南和土耳其心理学家协会的光盘进行渐进式肌肉放松练习。在数据分析中,独立样本t检验，费希尔的精确检验，和χ2检验用于比较个体，产科,和群体之间的医学特征。通过重复测量方差分析评估不同时间的依赖组之间的差异。
结果：与CG相比，渐进性肌肉放松练习中的疲劳症状有所改善-在8周结束时进行EG，和疲劳症状在CG中增加(P<0.001)。与CG相比，在8周结束时进行EG的渐进性肌肉放松练习的睡眠质量有更大的改善（P<0.001）。
结论：在我们的研究中，确定渐进性肌肉放松锻炼对睡眠质量和疲劳有改善作用。
