Introduction: Hypertension disorders are common in pregnancy and are major cause of maternity and neonatal mortality and morbidity. Although these disorders are accompanied by many difficulties in pregnancy, but not found effective therapy for those. There are hypothesises about role of stress in creation of hypertension disorders in pregnancy. From stress reduction programs such as muscle relaxation, Can used in care of essential hypertension. This study was done with purpose of determination of effectiveness Muscle relaxation on blood pressure in pregnancy.

Methods: This clinical trial was done in Mashhad community health cares in 2010. Pregnant women with systolic blood pressure≥ 135 mmHg or diastolic blood pressure≥ 85 mmHg, with simple method of sampling, entered in the study. Patients were divided in case and control groups randomly. Each group included 20 patients. In intervention group, muscle relaxation according to the Jacobson's technique, was performed one session in week personally, and in other days of week done with compact disk guidance, for 4 weeks. Blood pressure was controlled before and after the intervention in personal session in case group and before and after 15 minutes wait without special intervention in control group. Data was analyzed with SPSS software (version 11/5).

Results: Muscle relaxation significantly decreased systolic (p=0.001) and diastolic (p=0.001) blood pressure after 4 weeks of intervention in compare with control group.

Conclusion: According to the results, muscle relaxation can consider in decrease of systolic and diastolic blood pressure and care of gestational hypertension.
