Aim: The study aims to determine the effect of massage during pregnancy on women and their fetuses in a university hospital in Izmir, Turkey.

Method: The study was a randomized controlled experimental trial carried out with 20-35 years-old primipara pregnant women who came to obstetrics polyclinic of a university for evaluation of their first-trimester screen test's results, had no infertility story and were not at high risk (inclusion criteria). The participants were randomly allocated to the parallel comparison groups by a central office. The sample selection process in the study has been planned to be applied according to the CONSORT criteria (Moher et al. 2010) and the permutation method with blocked randomization has been done to the records assigned from the centre that the study was applied (Kanık, Tasdelen, and Erdogan 2011). In the process of collecting data, one blinding method has been applied, and it has only been applied to data analysis. Researchers aimed to reach 30 pregnant women at the start of the study. The completion decision of the data gathering process has been determined with power analysis that is carried out by the PASS program.

The study practices have been carried out after receiving ethics committee and institution approvals after the researcher completed the prenatal massage therapy training, and after taking the voluntary informed consent of the pregnant women. The practices have been carried out in the massage office that was formed within the scope of the study. Electronic fetal monitoring (EFM), BPP, vital signs, fetal heart rate (FHR) evaluation have been carried out for the pregnants whose routine gestational monitoring went on during their gestational week between the 30th and 34th in the control group, and Pregnant Description Form, VAS, Prenatal Attachment Inventory-PAI, Revised Prenatal Distress Questionnaire-PDQ have been applied. In the prenatal massage therapy group, between the 30th and 34th weeks, each week for five weeks, prenatal massage therapy including a 60 minutes deep tissue and Sweden massage methods had been applied once a week. Side-Lying Positioning System that is designed specifically for the pregnant has been used during the practices. In addition, the reason why the study group consisted of pregnant women in these weeks; Perinatology specialists recommend women to experience a deep and sustainable level of relaxation for 45-60 minutes before falling asleep, especially in the last 6-8 weeks of pregnancy, in preparation for labour (Osborne et al. 2021). In line with this suggestion, since the whole body massage has been performed in the research method, a 60-minute massage (30 minutes for each lateral position) has been applied.

Like before the prenatal massage therapy on the first date and after the prenatal massage therapy on the last date in the control group, all the forms and measurements have been applied. Pregnant women's VAS was measured before and after the prenatal massage therapy and the evaluation of the other measured data have been held between the 31st and 33rd gestational weeks. Also, Visual Analog Patient Satisfaction Scale-VAPSS has been measured after each prenatal massage therapy for finding satisfaction levels. In the process of the study, any significant side effect related to the practices hasn't occurred. The completion decision of the data gathering process has been determined with power analysis that was carried out by PASS program. The analysis of the study data has been carried out through SPSS 16 program.
