Balance platform: mathematical modeling for clinical evaluation

This study describes from a technological and mathematical point of view a systematic method for daily patient equilibrium evaluation during clinical work. We present the hardware commonly used for center-of-gravity determination and the basic tasks of the soft ware that runs in a personal computer, including an original procedure for rehabilitation measure. Using a simple approach, the method allows quantification of amelioration of the patient's condition and provides very useful (and, in practice, effective) distribution percent ages for visual, somatosensory, and vestibular contributions to stability or sensory equilibrium organization.
