To make a comprehensive analysis with a variety of diagnostic maneuvers is conducive to the correct diagnosis and classification of BPPV.
Based on the standard spatial coordinate-based semicircular canal model for theoretical observation on diagnostic maneuvers for benign paroxysmal positional vertigo (BPPV) to analyze the meaning and key point of each step of the maneuver.
This study started by building a standard model of semicircular canal with space orientation by segmentation of the inner ear done with the 3D Slicer software based on MRI scans, then gives a demonstration and observation of BPPV diagnostic maneuvers by using the model.
The supine roll maneuver is mainly for diagnosis of lateral semicircular canal BPPV. The Modified Dix-Hallpike maneuver is more specific for the diagnosis of posterior semicircular canal BPPV. The side-lying bow maneuver designed here is theoretically suitable for diagnosis of anterior semicircular canal BPPV.
采用多种诊断手法进行综合分析，有助于良性阵发性位置性眩晕（BPPV）的正确诊断与分型。
基于标准的基于空间坐标的半规管模型，对良性阵发性位置性眩晕（BPPV）的诊断手法进行理论观察，以分析手法各步骤的意义及要点。
本研究首先通过基于MRI扫描利用3D Slicer软件对内耳进行分割，构建具有空间定位的半规管标准模型，然后利用该模型对BPPV诊断手法进行演示与观察。
仰卧翻滚试验主要用于诊断水平半规管BPPV。改良Dix-Hallpike试验对后半规管BPPV的诊断更具特异性。此处设计的侧卧鞠躬试验理论上适用于前半规管BPPV的诊断。
