<![CDATA[Background: Pregnancy is a natural process that brings physical and psychological discomfort to pregnant women. One of the most common discomforts in the third trimester is lower back pain, which occurs due to increased production of the hormone relaxin, causing the pelvic bone joints to stretch and facilitate childbirth. Petrissage massage combined with lavender aromatherapy was administered to third-trimester pregnant women as a therapy to reduce this pain. Objective: This study aimed to determine the effect of a combination of petrissage massage and lavender aromatherapy on lower back pain in third-trimester pregnant women. Method: This quantitative study used a pre-experimental one-group pretest-posttest design without a control group, involving 15 samples of third-trimester pregnant women. The independent variable was the administration of petrissage massage and lavender aromatherapy, while the dependent variable was back pain. Pain was measured before and after the intervention using the Numeric Rating Scale (NRS). Result: The Wilcoxon test yielded a p value of 0.000, indicating that the combination of petrissage massage and lavender aromatherapy reduced lower back pain in third-trimester pregnant women. Conclusion: There is a significant effect of combined petrissage massage and lavender aromatherapy on lower back pain in third-trimester pregnant women; pregnant women can apply this combination as a nonpharmacological approach to reduce lower back pain.]]>
