Working on a computer for long periods of time can cause pain, soreness, and even injuries that will put you out of work. With this article, you will gain knowledge of proper ergonomics and links to sites that will help you stay healthy!
Technology certainly has its benefits, and it gives freelance writers more
opportunity and better efficiency. Clients can be found all over the world.
Communication is easy and convenient with email. The Internet is great for
finding the latest research. Parents can stay home with their kids and work
without commuting.
Unfortunately, with the benefits there comes a price. That price is aches
and pains. You may suffer with sore hands, back, neck, shoulders, and even
knees. You may take more aspirin than you would like, or even spend money on
new office furniture in an attempt to soothe your aches. However, many factors
may contribute to the pain, including poor posture, poor ergonomics, and/or
remaining sedentary. Repetitive tasks are one of the more popular things that
can cause some work-related injuries. This risk of injury is reduced by
ergonomics.
What is ergonomics?
According to an article in IFMA Journal, ergonomics matches the task,
tool and environment to fit the needs of people. It is a goal is to better fit
the worker and environment to achieve a healthy and productive workplace. There
needs to be a certainty with the design of office furniture specific to the
person and their capabilities.
Example of poor ergonomics –
According to Mary Ellen Modica, PT, MHS, a Physical
Therapist for 22 years who Specializes in treating orthopedic patients and
workers injured on the job:
A computer workstation for a short person would not be set up the same as a
station for someone 6 ft. tall. The short person would be looking up and
elevating their shoulders and flexing wrists to adapt. The tall person in a
"short persons" workstation would be flexing there neck, rounding
their shoulders. As you see, posture is poor in either scenario.
Injuries from Poor Ergonomics
The most common injuries are known as cumulative trauma disorders (CTDS) or
repetitive strain injuries (RSIs). They occur when the worker makes repeated
movements. It involves damage to the tendons, tendon sheaths or nerves of the
hands, wrists, elbows, shoulders, neck and/or back. The most common disorders
include carpal tunnel syndrome, tendonitis and tenosynovitis. The cause is
force, repetition and posture. The most common ailments for computer users are
low back pain, eye fatigue and muscle soreness.
The Occupational Safety and Health Administration (OSHA) lists ergonomics as
a key factor in preventing these injuries in the workplace.
Proper Posture
American Society of Hand Therapists (ASHT) member, Susan Johnson Melat's.
Susan is a Certified Hand Therapist (CHT) as well as an Occupational Therapist
(OTR) and Certified Vocational Evaluator (CVE). These are some of Susan’s tips
to adjust your working area for better health:
When working on a computer more than 2 hours per day follow these guidelines
to stay healthy:
Keep the keyboard and mouse
at the same level and at elbow height.
Adjust your chair height
first to allow your feet to be flat on the floor, lumbar support in low
back, armrests supporting arms, pan seat tilted forward and ear in line
with shoulder and hip.
Now adjust your keyboard tray
to elbow height. If on fixed surface, raise or lower chair to get the
keyboard and mouse at elbow height.
Position monitor so the top
of the screen is at eye level. A little lower if bifocal user.
Place documents on document
holder next to monitor and same height.
Place phone to non-dominant
side. Headset if on phone more than 2 hours per day.
Do not reach for mouse or
input device. Elbows should be at a 90 degree angle. Keep wrists straight.
Extra Tips for Creating a Healthy Workspace:
From Mary Ellen Modica, PT, MHS, and a Physical Therapist for 22 years:
The workstation must be customized for the individual. The chair should be
adjustable with 5 casters, upholstery and a water fall edge so there is no leg
pressure. It should be adjustable for height and seat angle. The chair is
adjusted so that the elbows are flexed to 90° and the wrists are in neutral.
Wrists should rest on a keyboard wrist rest and a mouse pad should be used to
decrease any pressure on the wrists. The top of the monitor should be at eye
level. There are risers available at office supply stores, but the hard drive
or even telephone books can be used to achieve the correct height. Feet should
rest on the floor. If this is not possible after adjusting the chair, a
footrest can be used.

Take Breaks!
You should be taking frequent breaks throughout your day. If you work an
eight hour shift with one lunch break, you should also take at least two extra
five to ten minute breaks to stretch.
Neck: bend your neck to the side to relieve shoulder
pressure and neck pressure.
Wrists: Flex and extend your wrists and hands with gentle pressure to
help relieve wrist strain.
Fingers: Open your fingers as wide as you can and hold for five
seconds. Then make fists and tighten as hard as you can. Hold for five seconds.
Eyes: Blink your eyes. Close them for a minute or so. Computer
screens can strain your eyes.
Body: Get up and walk around! Stretch your arms up as high as you
can, like you would upon wakening. Do some stretches that make you feel better.
Breath: Take a breather. When we work on computers, we tend to breath
short breaths. Take a few minutes to take long, slow, relaxing deep breaths.
This can help rejuvenate you and your body will certainly appreciate it.
Note: If you are experienced any long-term pain, strain, or soreness, you
should see your medical professional or physical therapist as soon as possible.
The National Institutes of Health (NIH) recommends the following stretches
for people who work on computer workstations:
There are many ways to stay healthy while working on a computer for long
periods of time. Ergonomics and taking breaks will help reduce your chances of
getting carpal tunnel syndrome, tendonitis and tenosynovitis, as well as damage
to your tendons, tendon sheaths or nerves of the hands, wrists, elbows,
shoulders, neck and/or back
