Amplitude and frequency of nystagmus

seems to be directly related to the severity of the vestibular problem.  The higher the frequency and amplitude of nystagmus, the more dizzy my clients seem to be.  Following repeated repositioning attempts, I recently observed severe nystagmus improve to, what seemed to be, 1/10th then 1/20th of a turn of torsion.  This was asymptomatic, however, I still believe it represented the problem still being present (at a much lesser degree).  Sometimes, it seems like the eyes are "loading."   Nystagmus does not occur, but the slow phase seems to begin.
