Dear Ray Wow! What an interesting study. I have a good friend who has suffered from Parkinson's for ten years. He is Mr Teo Kim Hoe, who is the one and only Parkinson's in Malaysia who regularly practices "forced" exercise as reported in this study. He is a very strong believer in exercise as a way to control the progression of Parkinson's. You can view the video recording of Mr Teo doing cycling (spinning) and kickboxing in his blog (www.heroteo.com) or Malaysian Parkinson's website (www.lloydtan-trust.com). Actually, many Parkinson's patients do carry out exercises, but these are usually light (e.g. morning walk, Tai Chi, waidangong, etc). But Mr Teo is diferent from other Parkinson's patients because he really forces himself to the maximum. I have seen him doing the kickboxing exercise, which I think is a "heavyweight" exercise. No other Parkinson's patients in Malaysia does the kickboxing exercise. In fact, the reason I decided to do video recording of Mr Teo doing all these "forced" exercises is to give motivation to the Parkinson's patients - that they can still be physically active despite having the illness.
