By using the Contraves computerized rotary chair system, trapezoid rotation (TR) test and sinusoidal harmonic acceleration (SHA) test were performed on each subject on the same day. The results in 25 normal volunteers and 145 patients with peripheral vestibular disorders were as follows: 1) As regards directional preponderance, the results of two rotation tests agreed in 75.9% of all patients, but a discrepancy was found in the rest. Abnormality was detected by TR test in 57.2% of all patients, and, less frequently, in 45.5% by SHA test. 2) In normal subjects, the maximum slow phase velocity of nystagmus provoked by TR test was greater than that of nystagmus provoked by SHA test using angular acceleration of a magnitude comparable to that in TR test. 3) As to the detection of abnormal VOR gain, the results of two rotation tests agreed in 100% of patients with bilateral vestibular disorders. However, in patients with unilateral vestibular disorders, the detection rate was higher for SHA test than that for TR test.
