Hello Rick
The Bean chair appears to be a variation on the exercise balls that are all the rage now ... with an advantage: the bean chair is stable in one dimension, unlike the spherical ball which is of coarse completely unstable.
The instability of the ball is why doing an exercise, say, pushups with your feet on the ball, is more effective than regular pushups: you're using additional muscles to maintain balance in addition to the usual muscles used in the usual form of the exercise. But this instability of the ball, and perhaps with the Bean chair, makes exercising with them a risky business for those recovering from lower back disorders ... at least initially, until a lot of one's flexibility and strength has been regained. It would seem that the Bean chair would be less risky, being more stable than a ball ... but I'd be cautious using one. Dr Stuart McGill experimented with the effectiveness of the ball and found them a superior exercise aid ... but gave the same cautionary warning to those of us with lower back disorders. Basically the same reason (risk outweighs benefit) that riding a motorbike is not wise, for a while, anyway, until your back is rebuilt. Thanks, Rick, for the web address.
Ken had an inversion table and found using his to provide some pain relief, short and long term. Several of his posts discuss his experiences with one. I regularly hang by the hands from a chinup bar, legs not touching ground, and find it gives a very relaxing stretch ... which I guess you might say is inverted inversion.
Dean recommended a book on the mind/body connection with healing. Can't recall the title, but it's in one of his posts. (can't find that post

anyone remember the book's title/author? I'd like to read it now) Dr. Pinker's book is not directly related to that topic. What I found interesting about his writing, which is unusually readable and humorous for a scientist, is that brain science is discovering that our so-called 'negative' emotions like anger, depression, fear, confusion, that we feel in times of crisis and change, can actually help us adapt to that change and heal. There's more to it than that, but some brain scientists are challenging some long held beliefs about our emotions.
A friend recovered from lymphoma cancer using nutritional therapy. She's a very strong-willed lady ... which gets back to the mind/body connection. The same treatments that worked for her, are ineffective for others. Makes you wonder ... a lot.
Dean's article on muscle memory is buried way down the blog column on the home page. Scroll past the articles on Dr. Barrett, stroke, and knuckle cracking.
It's easy to understand why the Social Security folks have to make it difficult to receive benefits; insurance fraud is no small problem. You just wish those who deserve the benefits didn't have to suffer from the rules designed to prevent fraud by lowlife.
