Biomechanical Investigation of Symptomatic FAI and Two Groups of Asymptomatic Controls

Every subject in this study will undergo a radiographic analysis of the hip and spine using a low-dose, full-body biplanar X-ray acquisition (in standing, sitting and squatting position, EOS imaging).

"A hip-specific 3D motion analysis will be performed. The 3D motion protocol will be divided into 2 main sections.~First section: Consist of movements categorized within the activities of daily living (walking at self-selected speed, uphill walking, standardized deep squat and non-standardized deep squat)~Second section: Consists of movements that are categorized within athletic training and have been specifically chosen to induce large hip ranges of motion (Sumo squats, dead lifts, forward lunges, running uphill and downhill)~Each movements will be repeated 6 times. Three times with the dominant foot/opposite leg on the force plate to collect kinetic data. All data will be captured using two 10-15 camera 3D motion capture systems and one capturing an instrumented treadmill (M-gait)"
