Lower Extremity Symmetry and Normative Values During Functional Performance Tests in Entry-Level U.S. Marines
Our study provides stakeholders (e.g., military personnel, clinicians, researchers, etc.) normative ranges of LSI performance values during a bodyweight bilateral squat, vertical jump, and IMTP tasks in a large healthy active duty population. Sex does not appear to influence LSI performance; however, limb dominance may influence loading patterns during these specific functional tasks. Given the similarities between the squat and vertical jump performance, future work should be conducted to determine if stakeholders should eliminate one of these tasks from the testing battery to mitigate the temporal burden required when completing functional task assessments in healthy active individuals.
