Aim & Objectives: The aim & objective of the study is to find out the Effect of William’s Flexion Exercises and Isometric Exercises on pain among college students with Primary Dysmenorrhea.

Methodology: A Pre-test and Post-test Quasi Experimental study design was used. A Convenient Sampling Method was used to recruit patients (N=20) diagnosed with Primary dysmenorrhea and they were randomized into two groups. The Group A was treated with William’s Flexion Exercises and the Group B was treated with Isometric Exercises for the period of 6 weeks. The treatment outcome was assessed by using Numeric Pain Rating Scale (NPRS). Both Paired & Unpaired‘t’ test was used to show the treatment effectiveness.

Result: After 6 weeks of training period the William’s Flexion Exercises scored significantly higher than the Isometric Exercises for pain using Numerical Pain Rating Scale (NPRS).

Conclusion: There is a significantly reduction in Pain intensity after the treatment session William’s Flexion Exercises group registered a significant improvement when compared to Isometric Exercises on relieving pain.
