Abstract
The peripheral effects of severe musculoskeletal injury are a well-studied phenomenon, but less well studied are the neural deficits. Past research has demonstrated that such severe injuries, specifically torn and reconstructed anterior cruciate ligament (ACL), may increase cognitive burden due to lack of afferent feedback from damaged nerves. This has previously shown to lead to delayed voluntary reactions in the lower extremities, but global neural changes are currently unknown. The goal of the conducted research was to determine whether neuromuscular deficits due to ACL injury and reconstruction in one limb influences motor behavior on a global level. Simple reaction time, choice reaction time, and go-no-go (e.g., response inhibition) tests were performed in the upper limbs using a basic computer with keyboard task. These tests were designed to detect these deficits in individuals with and without ACL injury and reconstruction. Since our preliminary data is not currently powered to detect differences in outcomes (i.e., p-value; 0.05), below we present preliminary data was analyzed using Repeated Measures ANOVAs.Individuals that had a prior ACL injury and reconstruction (n=5) were compared to healthy controls (CON; n=14). Preliminary evidence illustrates that individuals with prior ACL injury and reconstruction had. No differences were observed simple reaction time, choice reaction time, or go-no-go.While additional research is needed to determine potential global impairment created by ACL injury, preliminary results demonstrate there may be no difference in group. Lack of significance leads to the potential that ACL injury is not caused by an inherent delay in global reactions, but ACL injury may induce limb specific delay and thereby increase incidence of re-injury upon return to sport. Yet, further analysis is necessary. Funding: Research was supported by Utah State University Office of Research Undergraduate Research and Creative Opportunity (K. Reel, 2021).
