The aim of this study was to determine whether there is more deterioration in
walking under dual-task conditions in patients with bilateral vestibular loss
(BVL) than in healthy subjects, as opposed to the findings after unilateral loss.
For this purpose, 12 patients with BLV and 12 healthy control subjects performed
3 tasks: walking along a 10-m walkway, counting backwards by two, and both tasks
simultaneously. Patients did not differ from controls in their walking speed in
the single task condition, or in their cognitive performance in both the single
and dual-task conditions. However, walking performance was more affected in
patients than in controls under dual-task conditions, as shown by slower gait
speed in the dual-task, higher reduction in gait speed from single to dual-task,
and lower global dual-score. These findings provide evidence for greater
attentional interference between walking and counting in patients with BVL.
