I was at a Living Well With PD Conference put on by the National Parkinson Foundation. It was very informative. The speaker I was most impressed with was Gary Sobol. He Talked about An Effective PD Exercise Strategy, There Are No Shortcuts. This man was diagnosed with PD in 2008. He was to the point that he needed help with most activities of daily living, (ADL). He researched the benefits of exercise, then designed and created a exercise program for people with Parkinson. I was very impressed with the scope of His exercises. He covers it all. Voice, balance, cognition, flexibility. I wish there was a class close to us. That man worked hard to reclaim his life and now he is helping others to reclaim theirs. This is his website.
