A system and method for providing therapy and assessment utilizing vibrotactile feedback is disclosed. Such treatment is useful for the assessment and treatment of disequilibrium, movement and balance disorders. The system and method measures a subject's performance of predetermined tasks with respect to expected parameters using sensors such as force plates, inertial sensors, and three dimensional cameras. Predetermined motions are motions such as stand, sit-to-stand, reach, bend, functional gait, functional gait plus headshake, and other functional tasks. Vibrotactile stimulation may be applied during the subject's performance as disruptive input. Variance and rate of change of variance between measured and expected parameters is used as a tool for assessment of said subject, and is also used for providing real-time vibrotactile training to said subject. The invention is useful in the treatment of Traumatic Brain Injury (TBI), neurologic disorders causing disequilibrium and balance disorders, and the like.
