If you’ve been diagnosed with a repetitive strain injury, most chiropractors, physiotherapists and doctors will offer treatments that can reduce the pain and in some cases treat the disorder. But sometimes treatments are long and extensive and in the meanwhile it can be painful to carry out your work. In such cases, it may be a good idea to consider the office tools you have at your disposal. You may need help when setting up your workstation and choosing the products that can help you relieve the parts of your body that have suffered strain injuries.

Doing special exercises can be a good way to both relax and strengthen your muscles. The specific exercises will vary, depending on the muscles that have suffered strain injuries. Most physiotherapists will know a variety of exercises that might benefit you.

It might be challenging to design your home office in an ergonomically correct way, but there are some good guidelines for what you can do.

  • Pay attention to how long you stay in the same position
  • Change your position during the day (switch chairs or tables, use another mouse)
  • Take breaks away from the computer. E.g. walk around or sit on the couch during phone calls.


Work tools

Mice and keyboards have been shown to be among the leading causes of pain and strain injuries for office workers. So even though you may not have experienced discomfort from doing repetitive work, an ergonomic mouse helps prevent strain injuries and tension that can cause problems over time.

RollerMouse is a centred mouse developed in collaboration with ergonomic experts with the ambition to allow you to work in the best possible way for your body. With the RollerMouse placed in a centred position in front of the keyboard, you’re automatically placed in an ergonomic working position. This prevents the kind of over-stretching and twisting that you know from working with a traditional mouse. When using a RollerMouse, you’re using a tool that allows you to use both hands in a neutral and relaxed position close to your body. You avoid the unnatural grip on the mouse and instead you divide the strain evenly between your hands.

Even if you work with a traditional one-handed mouse, there are things you can do to minimize the risk of strain injuries. To avoid strain and discomfort, it’s important that your mouse fits your hand perfectly and provides optimal support and comfort. Your grip should be relaxed, so that you don’t bend your fingers too much, as this can excessively strain your hand and wrist, which in turn can cause mouse injuries. Especially with a one-handed mouse, where you use the same hand for doing all the mouse work, it’s important that your mouse fits your well and offers some sort of variation.
