“If you have a job without aggravations, you don’t have a job.” So
said the American publisher, Malcolm S. Forbes. While it may be true
that all jobs come with aggravations, no job has to come with the
physical pain associated with repetitive stress injuries.
Repetitive stress injuries are part of a category of occupational
injuries that occur when the human body performs the same physical
task over and over. There’s a whole alphabet of acronyms that are
used somewhat interchangeably to categorize these injuries:
· MSD (Musculoskeletal Disorders )
· UEMSD (Upper Extremity Musculoskeletal Disorder)
· RMI (Repetitive Motion Injury )
· RSI (Repetitive Stress Injury)
· CTD (Cumulative Trauma Disorder )
· WRULD (Work Related Upper Limb Disorders)
· OOS (Occupational Overuse Syndrome)
The bottom line on all of these is that the soft tissues of the body
can only take so much in terms of continuous irritation to one area.
Although workers on all kinds of jobs can suffer from RSI, people
who use computers are especially prone to them. So it’s important
for those folks to know how they can stay healthy and pain free as
they use technology on the job.
People may focus on the hand when it comes to preventing RSI, but
every part of the body needs to be properly positioned. Starting
with the feet. Dangling feet put a strain on the legs, neck, and
back. Many people can’t rest their feet on the floor once their
chairs are adjusted for keyboard use. The simple addition of a
footrest is all it takes to relieve muscle tension. Footrests
specifically designed for this purpose come in different heights.
They have gripper feet, and a nonslip surface. So even if a person
is, shall we say, a little vertically challenged, they can still sit
comfortably.
Your mother was always telling you to sit up straight, right? Well,
she knew what she was talking about. Poor posture in front of the
computer makes for big problems farther down the road. You can look
forward to pinched nerves, muscle spasms, and arthritis if you don’t
straighten up. If the spine is aligned properly, the muscles have a
chance to do their jobs efficiently. The muscles working in harmony
mean none are overused while some are underused. The most common
posture no-no? Slouching.
It’s no secret people carry tension in their shoulders. When you’re
working at your computer, are you holding your shoulders up by your
ears? If so, take a breath and let them relax. Your arms should hang
by your side, not too outstretched. If necessary, add an arm support
to your desk or chair. Ideally, your elbows should have about a 90
degree angle to them. And your work surface shouldn’t be too high.
An inch or two below your elbows is best.
Nobody likes to sit in the first row at the movies. It’s too
uncomfortable, craning your neck to see the screen. Check to see if
you sit that way when you look at your monitor. The monitor should
be positioned so that you look down slightly at it. And to make sure
your neck is in the best position, the focal point on your screen
should be somewhere between 1 degree and 60 degrees below
horizontal. By the way, don’t forget to blink!
Malcolm Forbes may have had plenty of aggravations over the span of
his career, but it’s certain he didn’t count RSI among them. If you
incorporate these simple ergonomic principles into your computer
use, neither will you.
