The effect of prophylactic knee bracing on performance: balance, proprioception, coordination, and muscular power.

摘要: Prophylactic knee braces are largely used in the prevention of ligament injuries, but their effectiveness on performance still controversial. The aim this study was to determine which brace most effective functional performance. Twenty-four healthy subjects (14 men and 10 women), between age 18 22 with no prior history lower limb injury use, voluntarily participated study. Five different prophylactic were used. test protocol consisted dynamic balance, jumping performance, proprioception, coordination, maximal force. Balance assessed by Y balance test; vertical jump one-leg hop tests; force, coordination using squat testing. Proprioceptive performed system machine that participants instructed keep crosshair line, even after visual aid had disappeared. without a 5 (DonJoy-USA) evaluated five therapists.
