头脉冲抑制试验

Suppression head impulse paradigm

摘要:

头脉冲抑制试验（suppression head impulse paradigm，SHIMP）是在头脉冲试验（head impulse paradigm, HIMP）或者视频头脉冲试验（video head impulse test，vHIT）基础上发展而来的一种新型检查技术。SHIMP和HIMP都是通过计算前庭眼动反射增益（vestibuloocular reflex gain，VOR gain）及校正性扫视（corrective saccades）来评估半规管功能的检查方法。VOR增益在两种检查中测定方法相似，扫视却相互补充：在HIMP中，代偿性扫视显示了前庭功能的损失，而在SHIMP中，反代偿性扫视显示了前庭功能的保留。本文就SHIMP的检测方法、原理及研究进展等进行综述。

Abstract:

Abstract:The suppression head impulse paradigm (SHIMP) is a new vestibular test protocol on the basis of head impulse paradigm (HIMP) or video head impulse test (vHIT). Both examinations evaluate semicircular canal functions according to VOR (vestibuleocular reex) gain and corrective saccades. The measurements and significance of VOR gain are the same in both examinations, while the corrective saccades are complementary: in HIMP test, compensatory saccades indicate vestibular loss, whereas in SHIMP test, anticompensatory saccades indicate vestibular function residual. In this article, the origin, development and the current research status of SHIMP are reviewed.
