Bauerfeind's GenuTrain S Pro offers active support with adjustable hinges for lateral stabilization. The anatomically shaped hinges can be adapted for better overall fit. They can be restricted to 30 degree, 60 degree or 90 degree flexion and 20 degree extension. Improved proprioceptive stimulation through compression provides improved awareness and stability. The design of patellar ring allows for intermittent compression during movement, enhancing the pain relieving effects of the support. The improved compression of the Train Knit helps to reduce swelling and improve healing.
