Clinical trials

The goal of this clinical trial is to find out whether exercise, motor imagery training, and pain neuroscience education can help reduce menstrual pain and improve well-being in young women with primary dysmenorrhea. The study will also look at how these approaches affect menstrual symptoms, movement control, and cognitive flexibility. The main questions it aims to answer are: * Does adding motor imagery or pain neuroscience education to an exercise program reduce pain and menstrual symptoms more than exercise alone? * Do these approaches improve movement control, thinking flexibility, and knowledge about pain? Researchers will compare three groups: * Exercise only * Exercise plus motor imagery training * Exercise plus pain neuroscience education Participants will: * Attend supervised exercise sessions twice a week for 8 weeks * Practice either motor imagery or receive short pain neuroscience education, depending on their group * Complete questionnaires and tests before and after the program, during the first three days of menstruation
