Iliotibial band syndrome (ITBS) is a common clinical presentation in runners. There are several hypotheses to explain this condition including faulty control of the hip joint in the frontal plane during the stance phase of running. It is postulated that improving activity in the gluteus medius muscle may assist in produc-ing more appropriate stabilization and therefore reduce the stress on the Iliotibial band (ITB). This single case study provides an interesting clinical scenario where a single-subject with ITBS was measured for hip kinematics during running, before and after a trial period of classic gluteus medius exercises. The biomechanical data show an initial (pre-intervention) increase in adduction position during the stance phase of running on the affected side (in contrast to the unaffected side). This was measured using a Moven motion analysis suit. After the trial intervention period, the relative position of the affected hip had reduced in adduction at both heel strike and at 30° knee flexion. This study provides support for the theory that hip control in the frontal plane may be a contributing factor in ITBS. Clinicians are encouraged to monitor hip control as well as ITBS symptoms when they utilise this gluteus medius protocol. Further research to establish whether change in pelvic control results in decrease in ITBS symptoms is warranted.
