Abstract: ［Abstract］Objective〖HTSS〗To evaluate vestibular ocular motility in patients with acute peripheral vertigo by observation of swivel rotation test.
〖WTHZ〗Methods〖HTSS〗A total of 146 patients with acute peripheral dizziness were selected, and divided into following groups:18 cases with bidirectional rotation abnormality group, 67 cases with left rotation abnormality group, 61 cases with right rotation abnormality group, and 30 healthy checkers were selected. Video nystagmogram detector was used to observe the changes of index, gain, time constant, gain asymmetry ratio and asymmetry ratio of time constant in patients' swivel emergency stop test in the semi-darkroom environment.
〖WTHZ〗Results〖HTSS〗When rotating to the left, the gain and time constant of the leftward rotation abnormal group and the bi-directional rotation abnormal group were lower than those of the control, the time constant of the rightward rotation abnormal group was lower than that of the control group（P＜0.01）. When rotating to the right, the gain and time constant of the rightward rotation abnormal group and the bi-directional rotation abnormal group were lower than those of the control group（P＜0.01）. When rotating to the left, the gain and time constant of the leftward rotation abnormal group  were lower than that rotating to the right（P＜0.01）. When rotating to the right, the gain and time constant of the rightward rotation abnormal group  were lower than that rotating to the left（P＜0.01）.The gain asymmetry ratio and time constant asymmetry ratio of the left-rotation abnormal group and the right-rotation abnormal group were significantly higher than that of the control group（P＜0.01）.The results of Logistic regression analysis showed that the right turn gain of swivel chair and the asymmetrical gain ratio of swivel chair were the influencing factors of peripheral vertigo（P＜0.01）.
〖WTHZ〗Conclusion〖HTSS〗The swivel chair rotation test can objectively evaluate the vestibular function of patients with acute peripheral vertigo and provide the dynamic change characteristics of the vestibular system after damage.
