OBJECTIVE: Spontaneous nystagmus is typical sign in vestibular neuronitis. However, the clinical significance of spontaneous nystagmus frequency remains unclear. The aim of this study is to analyze the spontaneous nystagmus frequency in patients with vestibular neuronitis.
METHODS
Twenty-five patients with vestibular neuronitis were included. Patients were divided good (≥20%) and poor (<20%) group according to change of spontanous nystagmus frequency. Frequency and velocity of spontaneous nystagmus were analyzed by using video-nystagmography. Caloric test and slow harmonic acceleration test were also performed.
RESULTS
There was a positive linear correlation between frequency and velocity in initial and follow test (R2=0.51, 0.43, p<0.01, p<0.01). Also, there was a strong positive linear correlation betweeng change of frequency and change of velocity (R2=0.64, p<0.01). The phase lead of slow harmonic acceleration test of good group was smaller compared with poor group, and this was statistically significant in 0.04 Hz.
CONCLUSION
We suggested that frequency of spontaneous nystagmus may be a useful clinical factor in vestibular neuronitis.
