Piriformis and Gluteal Muscle Thickness in Patients With Unilateral Greater Trochanteric Pain Syndrome

This study aims to evaluate muscle thickness in patients with unilateral Greater Trochanteric Pain Syndrome using ultrasonography and to compare these findings with healthy individuals. The primary objective is to determine whether piriformis muscle thickness differs between patients and controls. Secondary objectives include assessing gluteus medius and gluteus maximus muscle thickness, side-to-side differences in piriformis and gluteal muscle thickness, and the presence of Deep Gluteal Syndrome.
