Abstract

Background: Preeclampsia (PE), as the most common major pregnancy disorder, has serious maternal, fetal and neonatal complications, and outcomes. The present study was designed to determine the effectiveness of Jacobson's progressive muscle relaxation technique on maternal, fetal, and neonatal outcomes in women with non-severe preeclampsia (PE).

Methods: This is a randomized clinical trial conducted from March 21, 2021 to July 22, 2021 in the Kamali referral center in Karaj, Iran. A total of 88 eligible participants were assigned to intervention and control groups (44 in each group) via blocked randomization. The intervention group (6 groups of 6 participants and one group of 8 participants) received Jacobson's progressive muscle relaxation technique in addition to receiving routine care, twice a week for 6 weeks (4 face-to-face sessions and 8 online sessions). The control group only received routine perinatal care. A checklist collected data before and after the intervention. Data were analyzed in SPSS software v.23. To analyze the obtained data, independent t-test, Paired t-test, Mann-Whitney, Chi-square, and Fisher test were used.

Results: The results showed a statistically significant difference between intervention and control groups in terms of Systolic Blood pressure (SBP) (P < 0.001), Diastolic Blood pressure (DBP) (P < 0.001), 24-hour urine protein level (proteinuria) (P < 0.001). and Fasting Blood Sugar (FBS) (P < 0.001), birth Weight (BW) (P = 0.01), baseline Fetal heart rate (BFHR) (P < 0.001) and Number fetal movements based on non-stress test (NFMsN), during 20 min (P < 0.001) after intervention (P < 0.001).Also In the intervention group, the results showed a statistically significant difference in Amniotic Fluid Index (AFI) (P = 0.01), SBP(P < 0.001), DBP(P < 0.001), proteinuria (P < 0.001), FBS(P < 0.001), BFHR based on non-stress test (NST) (P < 0.001), and NFMsN during 20 min (P < 0.001) in the intervention group before and after the intervention. There was no statistically significant difference in the control group.

Conclusion: This study's results showed the effectiveness of progressive muscle relaxation technique on the improvement of SBP, DBP, proteinuria, FBS, FHR and NFMsN during 20 min based on NST and BW in women with non-severe PE. Therefore, it is recommended to perform this technique in health centers.
