Figure 1

Example of vestibular hypofunction seen across all frequencies for Case 1. A sinusoidal rotation at 0.04 Hz, 60 deg/s by rotational chair testing. The smooth sinusoid is the chair/head rotation at 0.04 Hz, and the scatter line represents the slow phases of compensatory nystagmus in response to the sinusoidal head (and chair) rotations. The abscissa is time measured in seconds. LB, left beating nystagmus; RB, right beating nystagmus. Performed using Micromedical Technologies (Chatham, IL, USA).
