Ergonomics is the discipline concerned with designing according to the needs of a person. There are custom made products that have the intention to help a user with comfort and easy usage of a mouse, laptop, keyboard, chair, or anything else in this nature, which helps avoid repetitive strain injury, also known as RSI. If repetitive strain injury is not addressed immediately, RSI can lead to serious injuries such as paralysis of the hand, chronic aching, arthritis, tendon and nerve damage, and other problems with the joints, cartilage, spine, and ligaments. A workstation that is not set up properly can lead to musculoskeletal disorders (MSD) and could lead to rotator cuff syndrome or carpal tunnel syndrome. MSD doesn't always come from bad posture, or a desk, it can also come from repetitive motions and awkward positions. Signs of carpal tunnel syndrome are usually having difficulty making a fist, weakness in body parts, having a hard time using hands, pain, soreness, swelling, and cold hands. So what can a person do to help prevent these sorts of problems?
It's important to think smart when it comes to designing your own workspace. Users with longer limbs could experience higher risks by having congested workspace. Make sure you have enough room. Also remember that standard desk sizes aren't always suitable for every person. If the desk is used by a group of people, then look to see if it can be adjusted. Make sure to organize the desktop in order to access items on your desk without any strain. Be sure to have the frequently used objects closer to avoid having to stretch to grab an item. If your feet don't rest on the floor comfortably, be sure to adjust your seat. If your feet still don't rest on the floor comfortably, be sure to get a footrest. It is also advised to use a document holder if you're constantly referring to documents while typing. This will prevent you from constantly having to move your head to look at the paper, and then moving your head to look at the computer.
Make sure that your monitor isn't too close or too far from you. This increases the chance of you sitting in an awkward position. Leaning forward to see the computer will put strain on your torso and will also strain the eyes. Make sure your monitor is clean to also prevent eyestrain and make sure the brightness of the monitor is at a comfortable level for you. Make sure the monitor is at a distance of 18-30 inches from you, and also make sure that it's at a 90-degree angle.
Not having enough lighting at your desk can also cause visual problems. The signs of visual discomfort are burning eyes, itching, eyestrain, and blurry vision. If you have a glare on your monitor, be sure to adjust the lights. Avoid any intense lighting at the workplace. If there isn't enough lighting at your desk, it is advised to get a desk lamp.
For serious ergonomic problems, it is always advised to speak to a professional Ergonomist.
