A system and method for providing therapy and assessment utilizing vibrotactile feedback is disclosed and claimed. Such treatment is useful for the treatment of disequilibrium and balance disorders. The system and method uses sensors such as force plates, inertial sensors, and three dimensional cameras to provide a subject with vibrotactile feedback in response to an attempt by the subject to perform predetermined motions. 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 of a functional gait task as a disruptive input. Variance and rate of change of variance between measured and expected parameters are determined and used as a tool for assessment, and may also be used for providing real-time vibrotactile training. Such assessment and therapy is useful in the treatment of Traumatic Brain Injury (TBI).
