Jim Caldwell asked about biofeedback & PD. My family physician referred me to a RN in my HMO for biofeedback last year. I was (and still do) having some problems with cold stiff hands, especially while working. I found that if I can sit quietly for about 10 minutes, I can use biofeedback techniques to relax muscles in my upper body, which leads to my hands warming up. This works fine when I'm sitting quietly at home and need to relax my muscles. However, it's another story when I'm at work and have several things going on at once. The RN who taught me to use biofeedback is also involved in sports medicine. She suggested that I use visualization techniques when I'm active. She suggested that I consider my individual and group T'ai Chi workouts as "practice" and try to visualize the mental/body state I experience then when I'm working. My work would be considered the "game." I've had mixed results with this. But I'm still "practicing" and trying to improve my "game." She also from the beginning told me PD is caused by a chemical deficiency in the brain and her techniques only supplement the medication. However her review of my medical records and her discussions with my family physician and with my neurologist did lead to some changes in my medications. Charley Countryman (46/6) [log in to unmask]
