With an ergonomic mouse, not only can you reduce pain and the effects of any repetitive strain injuries, but you can also prevent them. Therefore, even if you have not yet experienced mouse-related pain, it’s a good idea to use an ergonomic mouse as you are less likely to incur serious injuries, such as carpal tunnel syndrome, trigger finger, tennis elbow and other conditions caused by repeatedly clicking a mouse and one-sided repetitive work. You can then avoid taking a lot of sick leave as well as the considerable expense of getting massages and visiting a physiotherapist.
