A system and associated method for computerized rotational head impulse test (crHIT) to assess the semicircular canals of the human vestibular system clinically in patients with balance disorders. The system utilizes a rotary chair combined with a head mounted VOG system with head tracking sensors. The crHIT protocol uses the same physiologic principles as the known video head impulse test (vHIT). The crHIT utilizes whole-body rotation via the chair to yield a persistent controlled, repeatable, comfortable, reliable stimulus can be delivered while recording eye movements with video-oculogaphy.

Method for head impulse test

Apparatus and method for computerized rotational head impulse test

An apparatus for monitoring eye movement in a patient, includes a frame structured to be worn on the head of the patient. An infrared illumination device structured to illuminate an eye of the patient is supported by the frame. A camera structured to capture images of the eye when illuminated by the infrared illumination device is also supported by the frame. A number of sensors structured to generate data relating to one or more characteristics of the user or environment is further supported by the frame. The apparatus also includes a data storage device associated with the frame for recording the images and the data relating to one or more characteristics of the user or environment along with time information associated therewith. The apparatus is structured to generally not obstruct the patient's view of their surroundings.
