Sponsor's own description

Femoroacetabular impingement is an orthopedic condition that is primarily characterized by the presence of anatomic bony abnormalities in the femoral head and/or the acetabulum resulting in an abnormal contact between the two during hip motion, especially in positions of increased hip flexion and rotation, ultimately leading to hip pain.

The main study was initiated with the goal of exploring the etiology of FAI in a multidimensional and novel way that addresses the major gaps in literature. Within the main study a 3D motion capture protocol has been designed in line with the latest literature recommendations, which called for more hip ROM specific movements and athlete oriented 3D motion capture protocols that incorporate the spinopelvic complex. While the protocol surely contains movements that have been previously validated and published such as squats and lunges, a unique addition of high velocity soccer kicks and hop- lunges have been included.

Such additions elevate the relevancy of the 3D motion analysis protocol, however they also pose questions on how reliable and accurate these additions are. This is especially important a 3D motion analysis has a very subjective component, which is the placement of the skin markers by the clinician. Errors or alteration to markers placement between different sessions or different subjects have been shown to significantly affect the quality of data. Furthermore, not all physical movement can be properly documented using motion analysis. The velocity at which the movement is preformed combined with how complex it is can affect the quality of data collected by the motion analysis system. Also another important component is the uniqueness of the population recruited for the main study. Most studies with highly dynamic motion protocols have been validated and published on adult populations. Thus the investigators cannot use their findings liberally to compare with the adolescent protocol, as differences in patterns of motion between adults and adolescence have been documented. Indeed, a need to test the reliability of the investigators' protocol among their own study groups is highly imperative.
