<![CDATA[Sleep disturbance is a problem among patients with chronic kidney disease undergoing hemodialysis and may worsen fatigue, physical discomfort, daytime functioning, and quality of life. Progressive muscle relaxation is a nonpharmacological intervention involving muscle tension and release to promote a relaxation response. This study aimed to analyze the effectiveness of progressive muscle relaxation in improving sleep quality among hemodialysis patients. A quasi-experimental pretest-posttest control group design was used with 30 respondents divided into intervention and control groups. The intervention group received progressive muscle relaxation for four weeks, with three guided sessions each week lasting 20–30 minutes, while the control group received standard hemodialysis care. Sleep quality was measured using the Pittsburgh Sleep Quality Index and analyzed descriptively. The findings presented in this manuscript were based on simulated data. Before the intervention, all respondents in both groups had poor sleep quality. The mean PSQI score in the intervention group decreased from 13.1 to 7.4, whereas the control group changed from 12.9 to 12.3. Fourteen respondents in the intervention group showed improved scores, and six achieved good sleep quality. Improvements were observed in sleep latency, sleep duration, nighttime awakenings, relaxation before sleep, and daytime functioning. Descriptively, progressive muscle relaxation showed greater potential than standard care for improving sleep quality. This intervention may be considered a practical, safe, inexpensive, and teachable nursing measure, although studies with larger samples and inferential analyses remain necessary]]>
