Clinical significance of type 5 patterns in platform posturography.
Several abnormal patterns have been identified on the sensory portion of the computerized dynamic posturography test. The vestibular deficit pattern, also known as the "5-6" pattern, is frequently seen in patients with either uncompensated unilateral vestibular lesions, severe bilateral peripheral vestibular loss, or dysfunction involving the vestibular pathways in the brain stem and/or cerebellum. In both sensory conditions 5 and 6, the patient's balance/equilibrium is determined primarily by the vestibular system. A subgroup of the vestibular deficit pattern has been identified, in which only sensory condition 5 is abnormal. This article presents findings in several cases identified with the 5 pattern. Implications for diagnosis and for monitoring the recovery phase after treatment are discussed.
