Martina, Dad went through the traditional speech therapy for low voice (he can barely speak above a whisper) about a year ago. It was very difficult for him, since he was told only to use what words were necessary. For example, instead of saying "Could you please bring me my glasses?" he was taught to say only "Glasses, please." My father is a very intelligent man, which is usually signified in the length of utterance (at least this is what I've been taught through my training as a teacher of students with multiple disabilities-including speech/language disabilities). So, owing to this, it was very difficult for him to remember that he had to use only a few words to convey the same message! He also had to emphasize the vowel sounds with each utterance, and also had to concentrate on his posture: keeping his head up when speaking, keeping his back straight so he could get enough air when speaking, etc. This is really difficult for a person with Parkinson's! Through this list, Dad heard of a procedure that is currently being performed only in Los Angeles, CA at the UCLA Neck and Throat Clinic. Dr. Berke is going to give Dad the first in a series of bovine collagen injections that will tighten his vocal cords (the vocal cords in PWPs tend to remain apart, rather than come together) this Friday (Sept. 5). Depending on how long it takes for his body to absorb the collagen, Dad will have to return to UCLA four months after the initial injection, then every 6 months thereafter. We are hoping that someone here in Ohio will take an interest in learning the technique Dr. Berke uses, so that Dad won't have to do so much travelling! There are people here in Ohio who give the injections, however, no one here givesas been of some help to you! Trish
