They say it’s common knowledge nowadays that “sitting is the new smoking.”
If you need to sit for your occupation, even 50% of the time you can idealize the setup to prevent the risk of injuries.
Ergonomics is the study of people in their working environment. More specifically, an ergonomist plans and modifies or recommends the work to fit the worker, not the other way around. For example, ensuring the computer screen is at an ideal height, the chair is properly fitting, and the key keyboard tray ideal position, etc. The goal is to eliminate discomfort and risk of injury in the workplace.
If your work involves sitting at a desk, discomfort doesn’t have to be part of the job. You may be able to avoid some of the health problems associated with seated work, such as neck and back pain and sore wrists and shoulders, by using proper office ergonomics. Chair height, equipment spacing, and desk posture all make a difference.
We share the photo below with our patients to demonstrate the ideal workplace setup if their employer does not have access to an ergonomist to do this for them.
This ideal office setup will reduce stress on your body, protect your joints and help you stay comfortable as you work:
Optimizing Chair Setup For Better Posture
Choose a chair that supports your spine. Adjust the height of the chair so that your feet rest flatly on the floor or use a footrest so your thighs are parallel to the floor. If the chair has armrests, position them so your arms sit gently on the armrests with your elbows close to your body and your shoulders relaxed.
Desk Configurations For Increased Comfort
Under the desk, make sure there’s enough room for your legs and feet. Don’t store items under your desk, as that can shrink the amount of available space and make it hard to sit correctly. If the desk is too low and the desk height can’t be changed, put sturdy boards or blocks under the desk legs to raise it. If the desk is too high and can’t be changed, raise your chair. Use a footrest to support your feet if necessary. If you don’t have a footrest, try using a small stool or a stack of sturdy books. If your desk has a hard edge that’s not rounded, pad the edge or use a wrist rest. This protects your wrists from a problem called contact stress that can happen because of extended contact with a hard edge.
Keyboard And Mouse Positioning
Put your computer keyboard in front of you so your wrists and forearms are in line and your shoulders are relaxed. If you use a mouse or another type of pointer connected to a computer, place it within easy reach, on the same surface as your keyboard. While you are typing, using a computer touchpad, or using a mouse or pointer, keep your wrists straight (ie. The hand should be resting on the mouse and only moving side to side—so don’t have your hand at a level higher than your wrist). Keep your upper arms close to your body, and your hands at or slightly below the level of your elbows. If possible, set the sensitivity of the mouse or pointer so you can use a light touch on it.
Computer Monitor Arrangement
Place the computer monitor straight in front of you, directly behind your keyboard, about an arm’s length away from your face. The monitor should be no closer to you than 20 inches (about 50 centimetres) and no further away than 40 inches (about 100 centimetres). The top of the screen should be at or slightly below eye level. If you wear bifocals, lower the monitor an additional 1 to 2 inches (about 2 to 5 centimetres) for more comfortable viewing.
Ergonomic Considerations For Laptop Users
Using a laptop computer may lead to discomfort because of the low screen height and cramped keyboard and touchpad. If you use a laptop at your desk, consider getting an external keyboard and mouse, along with a laptop stand to more closely mimic a desktop computer setup.
Management Of Frequently Used Objects
Keep objects you use often—such as the phone, stapler or printed materials—close to your body to minimize reaching. Stand up to get anything that you can’t comfortably reach while sitting.
Telephone
If you spend a lot of time on the phone, or if you often type or write while you’re using the phone, put the phone on speaker or use a headset. Do not cradle the phone between your head and neck.
Remember, no matter how well your workspace is set up for proper ergonomics, sitting in the same position for hours at a time isn’t good for your body. Get up and walk around as often as you can throughout the workday. Ideally hourly. If possible, do some work standing up. While you’re seated, stretch your hands, fingers and arms from time to time. Shifting your position, standing up and moving will ease the strain on your body and help you stay pain and injury-free!
