[Saccadic sinusoidal tracking test].

This paper introduces a new method of ENG-Saccadic sinusoidal tracking test (SSTT). In 4 of the 55 cases with peripheral vestibular lesions, the results were abnormal. But among 50 cases with central lesions, 40 cases were abnormal. In 50 control cases, no abnormalities were found. The results showed that SSTT might be of great value in differential diagnosis of central Lesions.
