Abstract
OBJECTIVE
To describe the pattern of dynamic posturography or its role in diagnosis in patients with cerebellar ataxia with neuropathy and vestibular arreflexia syndrome (CANVAS).
MATERIALS AND METHODS
We present and describe posturographic data of four patients diagnosed with the CANVAS syndrome in a tertiary hospital.
RESULTS
In all patients, the average balance score was diminished. Two patients presented a pattern of visual dependence. The other two showed misuse of three posturography sensory information (visual, vestibular and propioceptive information), specially null use of vestibular information, deterioration of somatosensory input, and poor use of strategies, particularly in conditions 5 and 6.
CONCLUSIONS
If there is misuse of somatosensory information in sensory organization test (SOT) in a patient with bilateral vestibular deficit, a possibility of CANVAS should be considered. The SOT provides valuable information, because it evaluates sensory inputs influence the maintenance of balance.
