Iliotibial band syndrome (ITBS) is a condition frequently treated in physiotherapy. The pathophysiology underlying this syndrome is still poorly understood. Ultrasound makes it possible to evaluate the morphology and to quantify, with sonoelastography (SWE), the stiffness of the iliotibial band (ITB). The objective is to determine the feasibility of a cross-sectional study aimed at evaluating the morphometry and stiffness of the ITB in runners with and without a diagnosis of ITBS. Socio-demographic and clinical data will be collected and ultrasound measurements (thickness and stiffness) of the iliotibial band will be performed in supine with the knee positioned at 2 different angles (0° and 30° flexion). Variables such as the recruitment rate/month, the inclusion/exclusion rate, the acceptability of the procedure will be used to characterize the feasibility. The relationship between ultrasound measurements and clinical outcomes will be explored. The results obtained will document feasibility issues and provide preliminary results will lay the groundwork for a large scale study.
