Aclr performance during novel angle-matching task and dual-task

Despite the growing amount of literature suggesting a greater reliance on visual information and cognitive processing following an anterior cruciate ligament reconstruction (ACLR), no known study has investigated the interplay between cognition and visual feedback in an ACLR population. The purpose of this study was to determine 1) how performance is affected when visual feedback is removed, and 2) how manipulation of visual feedback and cognitive difficulty affects dual-task performance. Healthy controls (CON) and ACLR individuals performed a cognitive and angle-matching task separately and concurrently as a dual-task. ACLR individuals performed similarly to CON during single- and dual-tasks, regardless of visual feedback or cognitive difficulty. ACLR individuals were able to maintain motor performance in the absence of visual feedback, potentially by using other feedback mechanisms to perform the task equally well, thereby allowing more cognitive resources to be allocated to completion of the cognitive task.
