Quantitative Assessment of Head Impulse Test Using Stewart Platform

The Head impulse Test (HIT) has been widely used in the assessment of patients with vestibular deficits. However, the objectively quantified head impulse device has not been used in HIT yet. This study evaluates the Stewart platform through two test impulse commands that satisfied the angular velocity criteria of horizontal head impulse motion and measure the angular velocity response of platform by using IMU. The results showed the proposed Stewart platform satisfies the minimum peak velocity criteria (50 °/s) of manual head impulse motion. The evaluations prove that the 6-DOF Stewart platform has the potential to be an objective head impulse device in HIT.
