Reading Practise
Read the passage below and answer 10 questions.
Many people are affected by discomfort or injury resulting from the use of equipment which is not suited or not
adjusted for our bodies. If you have ever experienced pain in your hands after a lengthy session of typing, or
have had back pain after sitting at a desk for a long time, you will be able to imagine how much a person’s
productivity would be affected if these minor pains became persistent injury. Discomfort in the hands, back,
shoulders, elbows, and neck can be caused by overuse or misuse of the machines and equipment we use
everyday, and it is because of this that students and office workers alike are now learning about and applying
the principles of ergonomics, the practice of arranging an environment to suit the person using it.
While based in science and engineering, ergonomics has XXXXXXXXX applications that anyone can use on their
working or studying environment. How you position and use your computer, for example, can make all the
difference. Pay attention first of all to the height of the monitor. Too low and you are constantly looking down;
too high and you are constantly straining your neck to look up. Try to adjust the height of your monitor so that
the first line of text is at eye-level. You can also reduce the risk of discomfort in your wrists and the tendons of
your hands by making sure you type so that your wrists are suspended in the air, not resting against the desk
top. By making sure the mouse is right next to the keyboard, you can avoid having to stretch to reach it, and
therefore avoid unnecessary stress on your shoulder, elbow and wrist.
How you sit is also of vital importance in avoiding injury and discomfort, a fact which has directed chair design in
recent year. Today, it is easy to find ergonomically designed chairs which promise to reduce stress on your
back and legs when sitting for long periods, but it is not always easy to decide which one is best for you. You’ll
want to make sure the chair is adjustable in height and has a back which is at a 90 to 110 degree angle to the
chair seat. Whether or not the chair has a reclining back or armrests is more a matter of personal preference
than ergonomics, and as with using a computer, the best way to avoid discomfort is to adjust the equipment to
suit your body; the chair should be not so high as to cause strain on your legs, but not so low as to make typing
uncomfortable.
The principles of ergonomics make good sense, but the suggestions made above will reduce but not eliminate
discomfort associated with long periods at a desk. The best advice for avoiding repetitive stress injury at work
or home is tried and true – take breaks. Make sure you rest periodically during your work period. Five or ten
minutes every hour should do it. Take a short walk, make a cup of tea, anything which interrupts the repetitive
motions required when working or studying at a desk. The human body is designed for action, not long periods
of inaction, so regardless of how comfortable your surrounding environment is, you will feel some discomfort if
you stay in one position too long.
