Research Proposal Title:
In our everyday lives, we must adapt to different visual task constraints in our environment. When we approach a sign while walking and attempt to read the information of the sign, we modify the way we walk and often increase motion at the knee joint to enhance our ability to perform the visual task. Following ACL reconstruction, individuals rely more heavily on the hip and ankle, reducing the relative contributions from the reconstructed knee during locomotion. Altered knee joint loading puts these individuals at a greater risk for the development of knee joint osteoarthritis. How well can these individuals perform visual tasks during locomotion? Do visual tasks increase knee joint loading in these individuals? Understanding the effects of ACL reconstruction in more ecological settings has the potential to help improve rehabilitation strategies, knee joint health, and quality of life.
