Prevent CANS

Tips on CANS-prevention

If you work a lot in front of the computer it's important to be aware of and prevent pain in arms, neck and schoulders (CANS, also know as RSI or KANS in Dutch). Here we provide you with some top tips.

For the prevention of CANS/RSI a well adjusted workspace is key. Not everything is possible in your home situation, but try to adjust your workstation according to these three steps: chair, desk & computer. Make sure you at least raise your screen (use a laptop stand or even just some books) and use a separate keyboard. And of course, find a relaxed posture and alternate computer work with other work!

What do you need

  • Laptop (or desktop with screen)
  • Keyboard and mouse
  • Something to raise your screen with and maybe something to rais your desk with
  • a desk and an adjustable chair, or even just any chair for the time being 

Adjust workstation

  1. Adjust your chair
    1. Adjust the chair to the correct height. While standing the seat should be at the bottom of your kneecap.
    2. Adjust the seat allowing some space between the seat and your legs, a knuckle is more or less okay.
    3. Adjust the backrest so it provides support
    4. Adjust arm rest to support the arms. De arms should be relaxed and just supported in a 90 degrees angle.
  2. Adjust your desk
    1. Adjust the desk to the same height of the arm rest OR if not possible adjust the chair to the height of the table and use a footstool for support.
  3. Adjust your computer or laptop
    1. Adjust the top of the screen to eye level and an arms length away in case your able to type blind. In other cases place the screen slightly lower.
    2. The keyboard goes in front of your body, centrally placed and about 10cm away from your body. The mouse goes closely next to it.
  1. Don't work in front of the computer all the time
    1. The most important tip to prevent CANS is to take breaks regular. Set a timer for 30 minutes to remind you to take a break.

      Extra tip: don't use your smartphone during breaks!
    2. The pause software Wellnomics Workpace (WUR licence) or Workrave (Open Source) helps you to take micro breaks and longer breaks
    3. No need to sit inside all day. Take a walk, allow your eyes to rest and your body to relax.
    4. Don't keep drinks and snacks near your desk. It's better to take a short break and a small walk to the kitchen to refill. And use a smaller cup for your drinks ;)
