The goal of this Clinical Trial Study is to evaluate the clinical effectiveness of Radial Electrocorporeal Shockwave Therapy (rESWT) combined with exercise in individuals with iliotibial band syndrome (ITBS).The main question it aims to answer is : Does the addition of rESWT to standard ITBS exercise program reduce pain intensity and pain pressure threshold while improving lower extremity function and hip muscle strength in Individuals with Iliotibial Band syndrome (ITBS). Participants will be divided into two groups to be compared : The ShamTherapy Group (Control Group) that will receive the standard ITBS exercise program in addition to Sham rESWT, while the experimental group will receive the standard ITBS exercise program in addition to Radial Extracorporeal Shockwave Therapy.

The Iliotibial Band Syndrome is a frequently occurring overuse condition among runners and active individuals that often leads to persistent lateral knee pain and reduced function. Although exercise, particularly hip abductor strengthening, is considered effective, the optimal rehabilitation approach remains unclear. Recent evidence suggests that combining Radial Extracorporeal Shockwave Therapy with exercise may improve pain and function more than exercise alone.Therefore, evaluating whether the combination of rESWT and exercise is more effective than exercise alone is clinically relevant.
