My husband had DBS surgery in June 2009 for slow rigidity. He has had numerous programming sessions and still isn't doing as well as we had expected. I know the device is working but it is very sporadic. He can be on for 15 minutes and then off...then on for 5 minutes and then off. Sometimes he will be on for an hour for but then off for 4 hours. We think there may be something wrong with the battery, however they keep telling us it is working fine. He takes a 25/100 sinemet every two hours. Has anyone else that has had DBS surgery had this problem? We are going back to Mayo this week for yet another programming session.

Any help would be appreciated.
