Abstract:

Objective To analyze the characteristics of videonystagmography(VNG) parameters of vestibular central and peripheral vertigo patients. Methods Data on clinical manifestations and parameters of VNG were collected from 69 cases of vestibular central vertigo and 108 cases of vestibular peripheral vertigo, and then these data were analyzed and compared respectively. Results Compared with patients with vestibular peripheral vertigo, those with vestibular central vertigo were more common in male(P<0.001), older(P=0.009), shorter in course(P<0.001). The symptoms of diplopia(P<0.001), hemianesthesia weakness(P<0.001), slurred speech(P<0.001) were more often in patients with vestibular central vertigo. And cochlear symptoms(P=0.021) were more frequent in patients with vestibular peripheral vertigo. The duration of vertigo attack of vestibular central vertigo was longer(P<0.001). The onset of vestibular central vertigo was more related to body position(P<0.001). As compared with patients with vestibular peripheral vertigo, those with vestibular central vertigo demonstrated more abnormal in eye tracking test(40.6% vs 0.9%, P<0.001), calibration test(13.0% vs 0.0%, P<0.001), optokinetic test(10.1% vs 0.0%, P=0.003), gaze test(10.1% vs 0.0%, P=0.003), spontaneous nystagmus(8.7% vs 0.0%, P=0.007) or positional nystagmus(8.7% vs 0.0%, P=0.007). And positive positioning test was more common in patients with vestibular peripheral vertigo(14.5% vs 74.1%, P<0.001). Conclusion The features of VNG parameters are objective responses of nystagmus in vestibular vertigo patients. Combined with clinical features, they could help us distinguish vestibular central and peripheral vertigo.
