Primary dysmenorrhea, commonly known as menstrual cramps, is a prevalent gynecological issue that impacts many women in their childbearing age. It manifests as reoccurring, cramp-like lower abdominal pain, usually commencing right prior to or during the menstrual period. These painful sensations can be severe, extending to the lower back and upper thighs can greatly disrupt a woman's daily life and overall well-being. The optimal exercise approach is needed for individuals seeking relief from primary dysmenorrhea, allowing healthcare providers and women themselves to make informed decisions regarding their treatment options. Though many forms of exercise interventions exist in the treatment of primary dysmenorrhea,this study aimsto compare two forms of intervention namely pilates and gym ball exercises on pain and menstrual distress among women with Primary Dysmenorrhea. This experimental comparative study was carried out with 30 young female participants over a 12-week period. Participant recruitment was done through a simple random sampling method. The criteria of inclusion encompassed young females aged 17-25 years, those in good health, and those experiencing primary dysmenorrhea. Exclusion criteria included secondary dysmenorrhea, medication use, polycystic ovarian syndrome, bleeding disorders, positive pregnancy tests, breastfeeding, and other medical conditions. Group A received Pilates exercises, while Group B underwent Gym ball exercises. The assessment of both groups' menstrual distress levels was conducted using the Moos Menstrual Distress Questionnaire (MDQ) and pain scores using the Visual Analog Scale (VAS). In the statistical analysis, Group A (Pilates Exercises) showed a significantly lower mean value (2.60) on the VAS compared to Group B (Swiss Ball Exercises) (5.46), with both groups experiencing a notable reduction in post-test scores (p ≤ 0.001). Additionally, on the MOOS MDQ score, Group A (Pilates Exercises) achieved a lower mean value (79.33) compared to Group B (Swiss Ball Exercises) (103.26), with both groups demonstrating a significant decrease in post-test scores (p ≤ 0.001). In conclusion, this study underscores the significance of exercise therapy, particularly Pilates exercises, as a holistic approach to addressing primary dysmenorrhea, improving physical well-being, and enhancing the overall quality of life.
