Abstract

Context: Poor quadriceps force control has been observed after anterior cruciate ligament (ACL) reconstruction but has not been examined after ACL injury. Whether adaptations within the central nervous system are contributing to these impairments is unknown. Objective: To examine quadriceps force control in individuals who had sustained a recent ACL injury and determine the associations between cortical excitability and quadriceps force control in these individuals. Design: Cross-sectional study. Setting: Research laboratory. Patients or Other Participants: Eighteen individuals with a recent unilateral ACL injury (6 women, 12 men; age ¼ 29.6 6 8.4 years, height ¼ 1.74 6 0.07 m, mass ¼ 76.0 6..
