I e-wrote to the esteemed Charles Tauber of Toronto “If there is a bang about 6″ long with its raised end ridges rolling in two routed grooves I think, pending your advice, the platform could be something like 12″ long and 10″ wide with the two grooves six inches apart and two inches in from the 12″ edges. I think the grooves could be 11″ long. If not grooves maybesomething like box where a tool like a bang rolls between two walls ”
I mentioned to him that I am not sure if the ridges and grooves are best as v-shapes or square. Likewise, I am not sure about o-rings or just wood. In his reply he favors the two-sided box. I am guessing sufferers are barefoot or have a sock on but not a shoe. The challenge is to massage the foot equally without having the platform move around. I’d be trying to measure downward pressure along the grooves (pr the platform) with sensors.
My take at the moment is that tai chi bar is not very closely related to tai chi ruler. If one wants to say that much of tai chi bang is working on wrists and hands then I would say not much of a resemblance there either. There’s just no leverage applied to the ankle, for example.
I am still not persuaded that the tai chi bar in any of its variants is actually doing much, but some people swear by it, so I am staying the course. Readers may be amused to hear the variants include golf balls and baseballs as well as hard plastic dog bones. One comment I got a lot of was people needing to ‘massage’ their feet in the morning. I am not sure what was going on with sleeping but the claims are they were not really able to walk if they got straight up. So, the regimen is wake up, sit up on the edge of the bed, move one foot at a time over the tai chi bar or equivalent, then stand with support and move one foot at a time over the tai chi bar. Then they are ready to take on the day.
I was somewhat surprised to hear that this was not just seniors but people in their late 40s and even some teenagers. They are also reporting what is supposed to be positive flexing of the knees. If these folks had been serious cyclists or a marathon runners I could understand the impact of years of training in feet and knees. But everyone (so far) is very close to typical.
