Preeclampsia is a progressive disorder affecting multiple systems, which is distinguished by the
sudden appearance of high blood pressure and protein in the urine or other significant end-organ
dysfunction. Progressive muscle relaxation techniques is a useful technique to minimize stress, anxiety
and blood pressure among pregnant women with preeclampsia. The aim of this research was to evaluate
the effect of progressive muscle relaxation techniques on physiological parameters, psychological
factors and sleep quality among pregnant women with preeclampsia. Design: A quasi experimental
design (Two-Groups, Pre-test / Post-test). Setting: The research was conducted at obstetrics &
gynecological outpatient clinic in Benha university hospital. Sample: A purposive sample of 60
pregnant women with mild preeclampsia. Data collection tools: Five tools were used: A structured
interviewing questionnaire, Self-rating anxiety scale, Cohen perceived stress scale and Pittsburgh sleep
quality index. Results: The total score of knowledge and sleep quality in the study group showed
significant improvement post-intervention and two weeks post- intervention compared to pre
intervention while in the control group, there was minimal improvement. Also, the physiological
parameters, total level of anxiety and total level of stress were significantly decreased in the study group
post-intervention and two weeks post- intervention compared to control group. Conclusion: The
progressive muscle relaxation technique was effective and have a significant improvement of
knowledge, physiological parameters and psychological factors and sleep quality among women with
mild pregnancy induced hypertension. Recommendation: Pregnant women with hypertension should
be provided with relaxation techniques in antenatal care to improve knowledge, physiological
parameters and reduce blood pressure and stress level.
