Background:Fatigue and sleep disorders are experienced by most patients with Multiple Sclerosis (MS). Since these problems can interfere with a patient's daily functioning, this research examined the effects of Progressive Muscle Relaxation Technique (PMRT) on fatigue and sleep quality in patients with MS.

Methods:This quasi-experimental study adopted a pretest-posttest single group design. A total of 67 individuals with MS received a PMRT intervention for seven weeks. A demographic questionnaire, a PMRT form, the Fatigue Severity Scale (FSS), and the Pittsburgh Sleep Quality Index were used to collect data. Descriptive statistics, Wilcoxon test, and Spearman’s correlation analysis were used to analyze the data.

Result:The mean FSS scores were 5.25± 0.13 before the intervention 4.37 ± 0.13 after the intervention. Moreover, the mean sleep quality scores decreased from 8.34± 0.446 in pretest to 5.18± 0.345 in posttest (P < 0.001).

Conclusion:This study supported the beneficial effects of PMRT on reducing fatigue and improving sleep quality in patients with MS.
