Abstract
Hip osteoarthritis (OA) is a leading cause of pain and disability worldwide and is more prevalent among former elite athletes, particularly those who participated in high-impact sports during adolescence. Femoroacetabular impingement syndrome (FAIS), a common cause of hip and groin pain in young, physically active adults, is increasingly recognized as an important precursor to early-onset hip OA. Participation in high-impact youth sports, particularly soccer, has been strongly associated with the development of cam morphology, a bony deformity of the femoral head–neck junction, and subsequent symptomatic cam FAIS. However, the sport-specific hip kinematics and movement exposures thought to contribute to this condition remain poorly understood. While repetitive exposure to combined hip flexion, adduction, and internal rotation is thought to contribute to symptomatic cam FAIS, no validated tools currently exist to quantify the magnitude and frequency of exposure to these provocative hip positions during ecologically valid sport participation. This thesis addressed this gap through two complementary objectives. First, a wearable inertial measurement unit (IMU) system was validated against a gold-standard optical motion capture (OMC) system for quantifying three-dimensional hip kinematics during 35 soccer-specific movements performed by 20 elite adult soccer players (10 male, 10 female). Hip kinematics were compared using range of motion, root mean square error, Bland–Altman analysis, and the coefficient of multiple correlation. Second, five supervised machine-learning classifiers were developed and evaluated to automatically identify 20 soccer-specific movements from IMU-derived signals. . The findings demonstrate the feasibility of combining wearable IMUs with machine learning to provide valid, in-field estimates of sagittal and frontal plane hip joint angles and to distinguish a comprehensive range of soccer-specific movements associated with hip positions implicated in symptomatic cam FAIS.
