摘要: [摘要]
目的  观察转椅旋转试验对急性周围性眩晕患者前庭眼动功能的评价作用。
方法  选择急性周围性眩晕患者146例,分为双向旋转异常组18例、向左旋转异常组67例、向右旋转异常组61例,另选择健康体检者30例。在半暗室环境中,应用视频眼震图检测仪观察转椅旋转急停试验检测指标增益、时间常数、增益不对称比、时间常数不对称比的变化情况。
结果  向左旋转时,向左旋转异常组和双向旋转异常组的增益和时间常数低于对照组,向右旋转异常组的时间常数低于对照组(P<0.01);向右旋转时,向右旋转异常组和双向旋转异常组增益和时间常数低于对照组(P<0.01)。向左旋转异常组向左旋转时增益和时间常数低于向右旋转时(P<0.01);向右旋转异常组向右旋转时增益低于向左旋转时(P<0.01)。向左旋转异常组和向右旋转异常组的增益不对称比和时间常数不对称比明显高于对照组(P<0.01)。Logistic回归分析,结果显示,转椅右转增益、转椅增益不对称比是周围性眩晕的影响因素(P<0.05)。
结论  转椅旋转试验能够对急性周围性眩晕患者的前庭功能状态作出客观评价,可以提供前庭系统受损后的动态变化特征。

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.
