I think you're talking about the DynaFlex, which helped me quite a bit:

Also the powerWeb and the wrist roller:

Also, computer time means the smallest mouse i can find with decent action (Logitech, no model number I can find), and switching between Apple and Matias keyboards (short-travel and long, respectively) and carefully setting the tilt angle of the keyboard and height under heels of my hands (rolled up towel)
