[Electronystagmographic characteristics of peripheral vestibular asymmetries in compensation development stage II]

Spontaneous and reflex nystagmus of 10 patients with peripheral lesions of the vestibular system at one of the stages of vestibular dysfunction compensation development were examined. Spontaneous nystagmus (recovery) toward the sound side and asymmetry of reflex nystagmus in the form of DP toward the affected side were revealed. The period of disease characterized by the development of spontaneous and reflex nystagmus is termed compensation development stage II. This stage develops when central and peripheral compensation of vestibular dysfunction is realized simultaneously. Analysis of compensation development stage II helps to identify the compensation lesion level, side and degree of lesion of peripheral vestibular structures.
