Effect of ankle braces on frontal plane knee angle and moment and vertical jump performance

Usage of prophylactic ankle braces have been shown to reduce risk of injury while performing various jumping tasks, however the magnitude of the force acting on the knee has not been quantified. This study examined sagittal and frontal plane knee angle and moment at peak ground reaction force (vGRF) while performing braced maximal effort countermovement jumps. Lack of significant findings indicated that there is not a difference in jump performance as frontal plane knee angle, moment and movement patterns were similar in both males and females with braces.
