Talking about CTS with a mouse, a really great way to alleviate it is to get a set
of foot pedals. One for the left & right mouse buttons. Now you can relax the palm
of your hand on your mouse and just move while using your feet to click & select.
Sorta like driving a car. Hehe :)

| I'm not using this particular model, but I regularly use 3 different
| trackballs
| on 3 systems. I do a lot of CAD work, which requires fine pointing, down to
| just about single pixels on a 1024 x 768 screen. If I use a mouse, I tend to
| get a "death grip" on the thing, so that it doesn't move the cursor when I
| click a button. This definitely causes sore muscles and triggers something
| that I self-diagnosed as CTS. It might not be, but it WAS painful and lasted
| for almost a week. The trackballs leave the cursor where you put it when you
| click buttons, and their general mode of use doesn't give you anything to
| get a grip on, so your hand stays more relaxed. With one particular
| trackball,
| I still had a little trouble, and cut a piece of soft foam to rest the heel of
| my
| hand on, and that works real well. I have worn out the button switches on
| that one, and had to replace them!
|
| So, at least for me, and the work I do, I find that a trackball is a BIG help
| in
| not causing ergonomic problems.
