I recently worked with another individual who had pseudo-spontaneous nystagmus. Spontaneous nystagmus test with fixation blocked revealed a second degree left beat nystagmus. Vibration increased the spontaneous nystagmus in the same direction. Flexing the head 30 degrees abated the nystagmus and flexing 60 degrees created a very slow right beat nystagmus. It turned out to be left lateral canal cupulolithiasis that converted to canalithiasis fairly easily. On the same day following the treatment, the spontaneous nystagmus/second degree nystagmus was gone and vibration did not provoke the left beat nystagmus again.
