The Biodex Balance System SD is a sophisticated measuring and training device for static and dynamic balance testing and training.  The system measures vertical ground reaction forces produced by an athlete’s center of pressure.  The mCTSIB performed on the Balance System SD is designed to systematically test the sensory selection process by compromising available somatosensory, visual, and vestibular senses while measuring an athlete’s ability to minimize postural sway. The test provides a generalized assessment of how well an athlete can integrate various senses with respect to balance, and compensate when one or more of those senses are compromised.
