This study investigates if signal complexity is a useful measure to delineate between patients diagnosed with athletic groin pain (AGP) and uninjured controls. The 3D biomechanics of 65 AGP patients and 50 uninjured controls were examined during a lateral hurdle hop exercise. The complexity of hip moments was examined using quadratic sample entropy and statistically tested using independent t-tests. The results from this study demonstrated that the AGP group had significantly less complexity in hip moments in comparison to the uninjured control group with effect size ranging from 0.53 - 0.96. These findings would suggest that signal complexity of hip moments may be a useful measure to distinguish between those with and without AGP.
