Functional knee braces are often used by athletes following an injury to their anterior cruciate ligament (ACL). However, few athletes are given information as to whether the knee brace will hinder their ability. The purpose of this study was to examine the effects of a functional derotational knee brace on the single leg hop for distance, timed hop, and overall stability index of athletes. Twelve healthy knees were tested with and with out an off-the-shelf DonJoy Legend knee brace. A matched T-test showed a significant difference between the single leg hop (T = 2.71, p<.05) and timed hop (T=3.23, p<.05) while wearing the knee brace. There was no significance found when examining the stability index while wearing the brace. It was concluded that the functional knee brace decreased the distance of a single leg hop and increased the time it took to perform a timed hop.
