Keyboard & Mouse Set Up Tips
You've never worked like this before. With COVID-19, many of us have unexpectedly found ourselves working remotely full-time and needing to set-up new, functional workstations at home. This abrupt change in how you and I work can be
frustrating, let alone downright physically uncomfortable.

| Creating an Ergonomically-Sound Home Workstation |
Used to your familiar desk at the office, you are likely wondering how you can adapt and recreate that comfortable, ergonomic workspace at home. If you once worked at the office with a desktop computer with a huge monitor and keyboard, but now you're expected to produce the same work on your home computer desktop -- Or, even more challenging, using a laptop without that mouse you liked using at work -- you know what I am talking
about.
No wonder so many remote workers, including work at home moms and dads, are now experiencing unprecedented wrist pain, back strain and more fatigue lately that's affecting your overall wellness, family dynamics, not to mention seriously impacting your work productivity.
My goal is to help you set yourself up for success by showing you how to properly and comfortably use your
mouse and keyboard. So, in this post, I'll focus on how to properly position
your upper body relative to the keyboard and mouse as well as how to stretch
and work comfortably, even if you cannot achieve perfect ergonomics.
The Problems With Keyboard & Mouse Use
The keyboard and mouse can be your greatest source of pain. Why? Most of the time, these computer input devices are positioned too high. When both are elevated, you need to awkwardly reach up away from your body, placing increased stress on your shoulders. Additionally, when reaching for an improperly positioned keyboard and mouse, it causes you to bend forward at the wrist, placing increased stress on your tendons and nerves.

Limit Awkward Reaching/Bending at Your Computer
To align your body better and lower the position of the keyboard and mouse in relation to your wrists and shoulders, try one of these simple strategies
1) Lower the keyboard and mouse with a keyboard tray or move to a lower desk
2) Leave the keyboard and mouse as is, but raise your seat higher
Raising your chair or
lowering your mouse and keyboard will allow you to work in that comfortable
neutral posture: shoulders relaxed, elbows at your side at a 90-110
degree angle, with palms, wrists, and forearms aligned. If you always aim to achieve this neutral
posture whenever you are working with a keyboard and mouse you will be amazed at the difference it can make.
Solution 1: Lowering your Keyboard and Mouse
One of the best ways to work without reaching is to use a sit-stand desk. Some sit-stand desks like the IMovr Lander Desk allow you to lower the desk precisely to that ideal keyboard and mouse height.
If you do not have a desk of the proper height or don't want to invest in a good sit-stand desk, consider purchasing a keyboard tray. Though not for everyone, a keyboard tray will allow you to lower your keyboard and mouse so that you do not have to awkwardly reach up.
Ideally, I would recommend installing a fully adjustable keyboard tray like the Workrite Keyboard Trays to your existing desk. In situations where a full-on keyboard tray cannot be permanently attached -- because you work at the kitchen or dining room table, let's say --the Stand Up Desk Store Large Clamp On Keyboard Tray, which is portable and can be connected onto or removed from your work surface edge, is also an alternative that can work well.
However, before purchasing a keyboard tray of either type, be sure to check your desk’s shape (straight edges are fine, but circular desks won’t work). Also look for under desk obstacles (such as metal underneath) and measure desk thickness to ensure that the clamps properly attach, resulting in a stable and appropriate fit. Compare your existing desk surface details against the product’s specifications to find the right keyboard tray, assuring trouble-free installation when you attach your new keyboard tray under your desktop.
Solution 2: Raising Your Seat Height
Another solution is to simply to raise your seat. This is easily done if you have an adjustable chair. All you have to do is raise up
the seat height so that when you're sitting at your desk, your elbows are at your side and at a 90-110 degree
angle when working with the mouse and keyboard.
If you find that after raising the seat, your feet are dangling at
this elevated seat height, try using a ream of paper or a footrest to support
your feet in this more elevated position. If you aren't able to get the seat that high
or do not have an adjustable chair, try to sit on a pillow or seat cushion to
achieve the ergonomically-proper 90-110 degree elbow angle.
Other Recommendations for Comfort While Working
- Keep your elbow at your side (you may need to scoot yourself closer to the desk for this)
- Work toward always keeping your body properly aligned whether standing or sitting at your desk
- Alternate positions throughout the day to limit joint and muscle static postures and stress, standing for no more than 20 minutes every one to two hours
- Stand at the kitchen counter every hour for about 20 minutes if using a laptop computer
- Try taking phone calls standing up or walking while talking on your cell phone
- Stretch Wrists and Shoulders Often You definitely want to stretch your wrist and shoulders often during the day, too
Wrist Exercises
Below are two
effective wrist stretches that might help for those who, despite your best efforts, still notice you are awkwardly reaching up for
their keyboard and mouse and bending the wrist forward. Please note that if either of these stretches
causes you pain or discomfort, please stop the stretch and seek professional advice.
Wrist Extension #1 (for right and left wrist)
- Keep your wrist aligned with your forearm
- Look at the palm of your hand and slowly bring the palm back by extending wrist
- Bring your thumb back with your index finger gently and hold 5 seconds
- Repeat 3-5 times for the right and left wrist as tolerated and without pain
Wrist Extension #2 (for right and left wrist)
- Hold your hand out and keep palm up
- Bring your palm back gently
- Press back against palm with other hand, gently and mildly, hold for 5 seconds
- Repeat 3-5 times for the right and left wrist as tolerated and without pain
Conclusion
People often raise their hands and shoulders up to use the keyboard
and mouse without realizing it. This often results in unnecessary shoulder and wrist strain caused by the wrist being awkwardly bent
forward and the shoulders raised away from your body. In this story, several viable solutions have been provided to help with
this problem: stretching, alternating postures, raising the seat height or
using a keyboard tray or sit-stand desk.
These suggestions, when practiced consistently, can help maintain that comfortable neutral posture to aim for,
keeping your shoulders relaxed and wrist aligned with your palm and forearm.
