The invention relates to a system and method for measuring the biomechanical state of a subject using various sensors simultaneously with providing the subject with visual exercises for rehabilitation and assessment of disequilibrium, balance and motion disorders. The biomechanical state of a subject is measured during the subject's performance of a predetermined task. Such measurements are useful for the assessment of disequilibrium, balance and motion disorders and are also useful for the determination of therapeutic application of vibrotactile, auditory, or visual feedback to a subject during the subject's attempt to perform a predetermined task. An intelligent controller compares the subject's biomechanical state to a predetermined parameter to determine a variance. If the variance exceeds a threshold, feedback in the form of visual feedback, vibrotactile feedback or auditory feedback may be provided to the subject as a therapeutic means for enabling the subject to compensate for disorder effects.
