How can I prevent health problems from repeating the same movement over and over

If it is safe, switch hands or body positions as you work. Try to work in a way that bends the joint less and puts less pressure on it.
Try to exercise the joint every hour, by moving it through all of the motions it can make. This will stretch and strengthen the tendons and muscles. If exercise causes pain, move the joint slowly and gently.
