## Abstract

Project Summary
 Each year, as many as 250,000 individuals tear their anterior cruciate ligament (ACL) in the United
States, with over 75% undergoing an ACL reconstruction (ACLR). Despite completion of formal rehabilitation, a
significant portion of young individuals demonstrate persistent functional deficits at the time of return to pre-
injury sports participation and up to 30% of young, active individuals sustain a second ACL injury within months
of returning to sports participation. Traditional biomechanical methodologies assess individual components of
the movement system. However, the application of nonlinear methodology may uncover the underlying
mechanisms between the components of movement faults in a way that has the potential to uncover new
information about how the entire movement system interacts with its environment. There are many implications
for nonlinear methodology in rehabilitation research. As physical therapists, we are movement experts and
tailor our treatments to improve and enhance our patients’ abilities to move effectively. It is possible that the
ability to responsively tailor movement to the demands of the context in which they are imbedded may prevent
injury, whether that be an athlete sustaining a second ACL injury or an elderly individual sustaining a fracture
due to a fall. The innovative research described in this proposal has the potential to advance current
knowledge in ACL research and inform clinical care for athletes returning to sports after an ACL injury as well
as in other clinical populations. My goals for the training period include refining skills in rigorous research study
design, applications of nonlinear methodology and systems science theory, leadership and research
dissemination and professional development.
 The proposed research will take place at Ohio State University at the Martha Morehouse Pavillion and
the Jameson Crane Sports Medicine Institute. Both the Sports and Tactical Athlete Injury Resiliency Science
Laboratory in the Martha Morehouse Pavillion and the Jameson Crane Sports Medicine Institute have
dedicated faculty and staff members to ensure accurate and streamlined data acquisition with dedicated time
for student research with a multidisciplinary environment housing surgical suites, physician/surgeon’s offices, a
physical therapy clinic, surgical skills laboratory, and dedicated research office space with data analysis
software to provide a productive environment for analysis, interpretation and manuscript development. The
environment affords many collaborative interactions and ample resources to complete all data collections
outlined in this fellowship application. My sponsorship team consists of four university faculty members (3 at
Ohio State University and one at the University of Cincinnati). My sponsors have diverse areas of expertise
that are directly in line with their defined areas of contribution to the research and specific roles and
responsibilities over the course of th...
