Difference Effectiveness of Progressive Muscle Relaxation Therapy and Endorphin Massage Therapy towards Reducing Menstrual Pain Intensity in Adolescents

Background: Problems that arise during menstruation include pain before or during menstruation. Progressive Muscle Relaxation (PMR) techniques and Endorphin Massage (EM) therapy have been shown to be effective in controlling menstrual pain. The purpose of this study was to determine the difference in the effectiveness of pain intensity carried out by PMR therapy and EM therapy. Methods: Quasi-experimental research design with a two-group pretest and posttest design approach. Respondents were selected using a purposive sampling technique with inclusion and exclusion criteria. Students who experienced dysmenorrhea and do not have a genetic abnormality become the inclusion criteria of this study. Respondents who met the criteria were 80 respondents. Respondents were randomized using computerized to divide them into two groups. 40 respondents received PMR intervention and another 40 respondents received EM intervention. Bivariate analysis using Wilcoxon Test.  Identification of respondents who fit the criteria, namely adolescents aged 13-14 years who experience menstrual pain, and do not have genetic abnormalities. Pain measurement with NRS (Numeric Rating Scale) and analyzed using Mann-Whitney Test. Results: PMR is more effective in lower intensity painful menstruation compared with EM proven that the average painful menstruation after PMR of 2.42 + 0.675, while the average painful menstruation after EM is 2.90 + 0955 with a difference of 4.8 points with a significant 0.000. Menstrual pain can be reduced by blocking nerve impulses from reaching the brain, among others, by providing PMR therapy to control tension and anxiety. Conclusion: PMR therapy is more effective for controlling menstrual pain. PMR therapy can be done alone by adolescents when menstrual pain appears.
