Effectiveness of Progressive Muscle Relaxation Therapy on Quality of Sleep among Patients Admitted in Medical Ward of a Selected Hospital in Mangalore
To evaluate the effectiveness of progressive muscle relaxation (PMR) on quality of sleep of hospitalized medical patients of a selected hospital in Mangalore.
Randomized control trial was used to test the effectiveness of Jacobson's Progressive Muscle Relaxation Technique on quality of sleep (QOS) among 60 medical patients. The experimental group was subjected to the intervention (PMR) for 30 minutes daily for a period of 5 days. Both the groups (Experimental and Control) were observed with pretest and post test. The conceptual framework for the study was based on Systems Model developed from the General Systems Theory. Demographic proforma, Modified Pittsburgh sleep quality index and 3 point rating scale on assessing factors affecting Quality of sleep were used to collect data from the sample.
Nearly half of the subjects 28(46.6%) were above 41 years, both male and female constituted equal proportion 30 (50%) of the sample. All the respondents were literates (60%).Among the subject's majority 26 (43.3%) were Hindus, 40 (66.7%) had monthly income of <5000 rupees, majority belonged to nuclear family 53 (88.3%). Highest percentage of the subjects 23 (38.3%) were house wife and daily wage earners. More than half of the respondents 40 (66.7%).were diagnosed with renal, cardiac and other medical problems. None of them were practicing any form of alternative therapies, 31 (51.6%) of the sample were neither alcoholics nor smokers. The QOS was assessed in 84 patients admitted in medical ward out of which 60 (71.4%) had poor QOS and 24 (28.6%) had good QOS. The mean pre test score of QOS in the experimental (30) and control group (30) were 16.667 and 16.70 respectively. Psychological factors (74.137%) affected QOS more than the environmental factors (65.989%). Repeated measures ANOVA revealed a significant difference in the QOS from Day 1 to Day 5(. F cal=378.38>F tab (1, 4) = 7.71, p<0.005). The Bonferri multiple comparison test revealed a signifi cant improvement in the QOS from day 2 onwards. The calculated t-value of QOS was 17.892, was more than the table value t tab (58) = 2.00, p<0.05. Hence, the study revealed a significant improvement in the QOS in the experimental group after PMR. No significant association was found between QOS and selected demographic variables.
Sleep complaints are common during hospitalization and include delayed sleep onset, frequent awakening, restlessness and daytime sleepiness.Sleep is essential for health and quality of life. Practice of progressive muscle relaxation increases quality of sleep. The present study revealed that 5 days of progressive muscle relaxation therapy was very effective for medical patients with poor quality of sleep. Thus nurses have to be trained in providing cost effective, non pharmacological therapies like PMR to enhance the comfort of the client.
