The effect of auditory cues during running on impact forces of people with reconstructed anterior cruciate ligament

Anterior cruciate ligament (ACL) injury is one of the most frequent sports medicine injuries and characterized by reduced muscle strength, joint instability, and proprioceptive deficits. The long-term effects of these symptoms are excessive impact forces that are associated with knee osteoarthritis. The overall goal of the present project was to assess the efficacy of a real-time auditory feedback paradigm for reducing the magnitude of ground reaction (impact) forces in people with ACL reconstruction (ACLR). Our findings show that there was a decrease in impact forces due to feedback, but there was not a main effect of groups or interaction.
