PHYSICAL ACTIVITY AFTER ACL RECONSTRUCTION
Physical inactivity is the strongest predictor of morbidity and premature mortality among the American population. Significant musculoskeletal injury early in the life span can have negative effects on participation physical activity and engagement in sport. Our research is focused on assessing and addressing the effects of ACL reconstruction (ACLR) on objective and patient-reported measures of physical activity, and cardiovascular health among young and otherwise healthy individuals with the goal of promoting long-term health and wellbeing.

PERCEPTIONS RETURN TO ACTIVITY AFTER ACL RECONSTRUCTION
Patients struggle to return to pre-injury levels of activity following anterior cruciate ligament reconstruction (ACLR) for physical and psychosocial reasons. Our research focuses on the ability to integrate contextual evidence obtained directly from patients with the growing body of quantitative rehabilitation research in order to aid clinicians in taking an evidence-based approach to rehabilitation and return to sport.

NEUROMUSCULAR FUNCTION AFTER ACL RECONSTRUCTION
Identification of individuals at risk for poor outcomes following ACL reconstruction (ACLR) is an essential step in facilitating a timely, safe, and healthy return to physical activity. Our research focuses on identifying peripheral and central neuromuscular risk factors for compromised joint health and poor knee related outcomes following ACLR. Currently, the SIRL is utilizing a variety of techniques including assessment of muscle strength and function, direct and indirect assessment of muscle structure and function to pursue this area of research.

LOWER EXTREMITY BIOMECHANICS AFTER ACL RECONSTRUCTION
Cost effective and objective assessment of lower extremity function and physical activity characteristics represent a clear improvement over standard tools for clinical evaluation of injury risk factors as well as progression throughout clinical rehabilitation. Our current research focuses on the integration of commercially available video game technology and advanced machine learning modeling techniques to facilitate objective measurement of lower extremity function in the clinical environment and phsyical activity characteristics in the field.
