The objective of the present study is to analyze the quantitative vestibulo-ocular responses in a group of patients with benign paroxysmal positional vertigo (BPPV) canalolithiasis and compare these data with the data of the tridimensional biomechanical model. This study was conducted on 70 patients that presented idiopathic posterior semicircular canal canalolithiasis. The diagnosis was obtained by Dix-Hallpike maneuvers recorded by videonystagmograph. The present study demonstrates that there is a significant correlation between the intensity of the nystagmus and its latency in cases of BPPV-idiopathic posterior semicircular canal canalolithiasis type. These findings are in agreement with those obtained in a tridimensional biomechanical model and are not related to the patients' age.
本研究的目的是分析一组良性阵发性位置性眩晕(BPPV)管结石症患者的定量前庭眼反射,并将这些数据与三维生物力学模型的数据进行比较。本研究针对70例特发性后半规管管结石症患者开展。诊断通过视频眼震图记录的Dix-Hallpike试验获得。本研究表明,在BPPV-特发性后半规管管结石症类型的病例中,眼震强度与其潜伏期之间存在显著相关性。这些发现与三维生物力学模型中获得的结果一致,且与患者年龄无关。
