AutoMouseClicker will automatically click the mouse for you, you can set it to click only after you move the mouse and to wait a certain amount of time.  This helps lessen the strain on your injuries. The less clicking the better. Best of all, it is free.

Of course, the best bet is to try to minimize use of your computer! That works the best.

The Dragon NaturallySpeaking 10 Preferred is a low cost voice recognition software that I use. I started using it at version 6 and have found that it has improved substantially. It includes a high-quality headset.

The speed and accuracy is pretty good and I like the voice web navigation it offers. It is not perfect but less typing = more healing. It is hard to use in an open office environment though.
