Is it ok to use vibration with individuals who have a history of seizures?

The question of whether or not vibration causes or is connected to seizures resurfaces from time to time.  We believe it originated sometime back in the 60s or 70s with no information or study available that we can find to back up the question.  We’ve asked many  neurologists over the years, and they are always surprised by the question and see no correlation.  However, our guideline has ALWAYS been to check with the individual's physician and neurologist if there are any concerns.  Each individual is wired differently, and the extra precaution never hurts.
