Objectives: Athletes commonly wear fitted silicone ankle sleeves (SAS) and lace-up ankle braces (LAB). There is limited data about their effect on neuromuscular control or athletic performance. Our goal is to evaluate their efficacy in a young, active population during athletic tasks using motion analysis. Methods: Ten subjects (5 males, 5 females) without prior musculoskeletal injury were recruited. They were asked to perform the Drop Vertical Jump test (DVJ), 45 degree bound, and cutting maneuvers under three conditions: No brace, SAS, LAB. DVJ was used as a surrogate for neuromuscular control, and the 45 degree bound and cutting for athletic performance. Tasks were performed in separate sessions to minimize effects of fatigue. Markerless motion-capture technology was used for data collection. For the DVJ, knee flexion, hip internal rotation, and dynamic valgus were measured during both contact and loading phases of landing. Ankle torque and range of motion were also evaluated. For the 45 degree bound, ankle torque was measured during the initial movement to the dominant knee. Performance time for the cutting with the dominant pivot foot was recorded. Statistics were calculated using a two-tailed Student's t-test with significance set at p=0.05. Results: When compared to controls for both the contact and loading phases of the DVJ, use of the SAS or LAB demonstrated significantly decreased hip internal rotation (67%, 15%, respectively), ankle torque (13%, 11% respectively), and ankle range of motion (p
