This study aimed to compare the effects of proprioceptive and core training on pain, function, and performance among athletes diagnosed with sacroiliac joint (SIJ) dysfunction. Thirty athletes aged 20–30 years were randomly assigned to two equal groups: Group A (Proprioceptive Training) and Group B (Core Training). Both interventions were conducted three times per week for six weeks. Outcome measures included pain intensity using the Visual Analogue Scale (VAS), functional disability via the Oswestry Disability Index (ODI), range of motion (ROM), balance through the Y-Balance Test, and athletic performance using an Agility T-test. Results demonstrated significant improvements (p < 0.05) in both groups post-intervention, but Group A exhibited greater gains in pain reduction, ROM, and performance measures. These findings suggest that proprioceptive training is superior to isolated core exercises in optimizing function and performance in athletes with SIJ dysfunction.
