@wsh66 Stephen, my Tai Chi Chuan master always taught us to be seated if we could not stand the entire 40 minute routine. I have visualized Tai Chi routines while undergoing medical procedures, which has done wonders for keeping calm! Always have been curious of there would be a way to watch my brainwaves while doing that in a medical setting.

"Controlling depression and stress are essential to pain management. How much pain we have is a physical metric. How we experience that pain is a psychological metric." Well said, Stephen
