The impulsive test in man.
The impulsive test is brief and comfortable to the patient. The SVM is the best discriminator of the variables examined. By using percent differences between CW and CCW responses in the same subject at the same stimulus magnitude, we can define a range for the normal population and indicate patients outside that normal range. The impulsive test gives directional information in patients with unilateral lesions. In patients with severe bilateral loss of vestibular function, measurable responses are still obtainable; while in patients with primary cerebellar disease, responses are increased. The test may also be useful in giving anatomic information about posterior fossa lesions.
