Background and Objectives Even patients with compensated peripheral vestibular dysfunction may report a sense of disequilibrium during daily activities, which often fail conventional vestibular function tests as attentional demand required for postural control may increase in these patients. The study aims to assess the feasibility of dual task test using concurrent cognitive tasks in a modified clinical test of sensory interaction on balance (mCTSIB) to measure increased attentional demand for posture control. Subjects and Method Nineteen patients suspected with chronic dizziness were recruited by history reviews and physical examinations. Data for center of pressure (COP) variability and mean velocity during mCTSIB on a force long plate were analyzed, and time taken to react to the auditory stimuli were used to measure the attentional demand required for adequate postural control during platform perturbation. Results The mean COP range and velocity during mCTSIB were comparable between single and dual task conditions in patients with dizziness. Reaction time (RT) to auditory stimulus of 1 kHz pure tone in patients with chronic dizziness was also comparable to normal subjects. Interestingly, there was a tendency for increased RT in patients with documented caloric weakness, suggesting that attentional demand is increased in these patients. Conclusion RT of dual task tests using auditory stimuli during mCTSIB may provide additional information about increased attentional demand for postural control in patients with vestibular dysfunction.
