<I>Objective.</I> To investigate the effects of prophylactic knee bracing on proprioceptive performance among first division rugby union players during a 2-minute Wilknox Quad Time Logger balancing task. <br><I>Design.</I> Each subject performed a 2-minute balancing task on the Wilknox Quad Time Logger. Test order, left or right leg, and the sequence of brace or non-brace, were randomised. Subjects were placed on the balancing board and instructed to balance for 2 minutes. Subjects performed 6 trials. Two days elapsed between testing. Each testing day involved 2 trials, 1 trial with and 1 without the prophylactic knee brace. <br><I>Settings.</I> Testing took place at the biokinetics laboratory of the University of Zululand. <br><I>Subjects.</I> Thirty playing (not injured) male rugby players, aged 22 - 30 years, participating in the KwaZulu-Natal club championships (2000). <br><I>Outcome measure.</I> Performance was measured in terms of time that balance was lost in a dynamic balance test. Peak proprioception was the best balancing performance recorded, and average proprioception the average balancing performance for all trials. <br><I>Results.</I> The findings showed an improvement of 17.9% in average proprioception times and 19.1% in peak proprioception times with the application of a prophylactic knee brace (<I>p</I> < 0.01). Conclusion. Prophylactic knee bracing improved proprioception performance of playing (uninjured) rugby players, and therefore may be responsible for the improvement in knee injury statistics reported in some studies on knee bracing.
