This study aimed to evaluate the effect of progressive muscle relaxation exercises (PMRE) on sleep quality in patients undergoing chemotherapy treatment and experiencing disturbed sleep. The prospective randomized controlled study was conducted between March and September 2022 with 69 patients (intervention group: 34 patients, control group: 35 patients) in a hospital chemotherapy unit. During the data collection process, the “Personal Information Form” and “Pittsburgh Sleep Quality Index (PSQI)” were utilized. Patients in the intervention group performed PMRE twice a day for 8 weeks. Patients in the control group received routine care at the clinic without additional intervention. For data analysis, Student's -test, Mann–Whitney U test, Fisher's exact test, and chi-square test were used. The sociodemographic attributes of patients within both the intervention and control groups exhibited comparability. However, notable distinctions emerged in the PSQI Global sleep score and PSQI subdimension scores, encompassing sleep latency and duration, subjective sleep quality, habitual sleep efficiency, sleep disturbance, and daytime dysfunction between the two groups. The study found a notable difference in scores between the patients in the intervention group and those in the control group. The patients who received the intervention had significantly lower scores ( < .001). The study revealed that PMRE was beneficial in improving sleep quality in cancer patients undergoing chemotherapy who had poor sleep quality. Oncology nurses may consider using PMRE to improve the sleep quality of cancer patients receiving chemotherapy.

渐进式肌肉放松运动对接受化疗的癌症患者睡眠质量的影响：一项随机对照研究

本研究旨在评估渐进式肌肉放松练习 (PMRE) 对接受化疗和睡眠不安的患者睡眠质量的影响。该前瞻性随机对照研究于2022年3月至9月在医院化疗室进行，共有69名患者（干预组：34名患者，对照组：35名患者）。在数据收集过程中，使用了“个人信息表”和“匹兹堡睡眠质量指数（PSQI）”。干预组的患者每天进行两次 PMRE，持续 8 周。对照组患者在诊所接受常规护理，无需额外干预。对于数据分析，使用了Student's 检验、Mann-Whitney U 检验、Fisher 精确检验和卡方检验。干预组和对照组患者的社会人口统计学特征表现出可比性。然而，两组之间的 PSQI 总体睡眠评分和 PSQI 子维度评分存在显着差异，包括睡眠潜伏期和持续时间、主观睡眠质量、习惯性睡眠效率、睡眠障碍和日间功能障碍。研究发现干预组患者和对照组患者的评分存在显着差异。接受干预的患者得分显着较低 (<.001)。研究表明，PMRE 有利于改善睡眠质量较差的接受化疗的癌症患者的睡眠质量。肿瘤科护士可以考虑使用 PMRE 来改善接受化疗的癌症患者的睡眠质量。
