This study investigated DT interference during gait in a middle-aged group of subjects with dizziness and unsteadiness after unilateral vestibular neuronitis and in a healthy control group. Methods Fourteen individuals with subacute unilateral vestibular impairment after neuronitis and seventeen healthy subjects performed gait and cognitive tasks in single and DT conditions. A statistical gait analysis system was used and spatio-temporal parameters were considered. The cognitive task consisting of backward counting by three was tape recorded and the number of right figures was then calculated. Results Both patients and controls showed a more conservative gait during DT and between groups significant differences were not found. A significant decrease in cognitive performance during DT was found only in the vestibular group. Conclusions Results suggest that less attentional resources are available during gait in vestibular patients compared to controls and that a priority is given in keeping up the motor task to the detriment of a decrease of the cognitive performance during DT. Background Vestibular information is important during gait together with vision and somatosensory input 1 . In fact galvanic vestibular stimulation experimentally producing functional imbalance between the two vestibular apparatus causes in healthy subjects gait deviation to the anodal side 2 . Moreover gait unsteadiness is a common complaint after vestibular neuritis
