Self-Assessment
Guide for Computer Users
With this checklist, the more "YES" answers there are, the better.
This is particularly important for intensive computer users (more than
5 hours per day at the computer) as well as moderate computer users (3-5
hours per day at the computer). This checklist
is also available in "pdf format" here.
| |
YES |
NO |
| Are the shoulders relaxed, elbows close to the
sides (i.e. arms are not reaching), forearms roughly horizontal and wrists
straight while using the keyboard?
If no, adjust the chair height and/or keyboard height.
|
|
|
| Is there some space in front
of the keyboard to allow the user to rest the wrists when not actively
keyboarding?
If no, try to provide about 2-3
inches of space for the wrists and palms to rest on when not actively keyboarding.
Also, ensure that the wrists and palms are not resting on sharp edges or
similar pressure points.
|
|
|
| Do the wrists remain "free"
and not resting on the desk surface or wrist rest while actively keyboarding?
If no, try to avoid "planting"
the wrists and palms on surfaces such as the desk or a wrist rest since
this tends to cause deviation of the wrists. Use those surfaces when not
actively keyboarding.

|
When seated, is the lower
back well supported and remain in contact with the backrest of the chair
while performing computer work?
If no, consider the following:
-
adjust the backrest of the chair (i.e.
adjust height, move backrest forward horizontally, adjust tilt)
-
try a pillow or strap-on back support
to ensure that the back is in contact with the backrest
-
try a footrest to assist with sitting
posture
|
|
|
| While sitting, are the knees
bent (about 90o) and the thighs roughly horizontal?
If no, adjust height of chair
accordingly.
|
|
|
| When seated, is there a space
about the width of a clenched fist between the back of the knee and the
front of the chair?
If no, move the backrest forward
horizontally or try adding a pillow or strap-on back support to help "shorten"
the length of the seat pan.
|
|
|
| When seated, can the feet
rest comfortably on the floor?
If no, the keyboard height may
need to be lowered or a footrest may be required.
|
|
|
| While seated at the workstation,
are the ears, shoulders and hips lined up vertically?
If no, make necessary adjustments
to the chair height, the angle of the backrest, keyboard height, viewing
distance and/or the height of the computer monitor.
|
|
|
| Is the mouse or other pointing
device located close to, and at about the same height as, the keyboard?
If no, bring the mouse device
closer to the keyboard, at about the same height. The upper arm should
be close to the body and the elbow should be bent (about 90o)
and close to the sides. The wrist should be relatively straight, not deviated
to the left or right or up or down.
|
|
|
Is a document holder available
for frequently used documents or reference materials?
If no, use a document holder
that is positioned to either side of the monitor or, if the workstation
permits it, prop the documents "in-line", between the monitor and keyboard.
|
|
|
| Are frequently used items
such as files, telephone, etc. placed within easy reach (i.e. avoiding
frequent above shoulder reaches or frequent twists or turns of the spine). |
|
|
| Does the user take frequent
vision breaks for refreshing the eyes?
If no, and the user often experiences
dry, itchy, irritated, tired eyes and/or headaches and eyestrain, remember
that for every 30 minutes of intensive computer users, rest the eyes by
glancing away from the monitor and focussing on a distant object for about
15 seconds before resuming work on the computer.
|
|
|
| Does the user take physical
breaks and move about frequently during the day (such as stretching exercises
performed at the desk, moving or walking about to perform different tasks,
changing sitting postures, etc.)
If no, remember that for every
hour of intensive computer use, try to take about 5 minutes away from the
computer to stretch, perform a different task, etc.Humans cannot remain
in one position for hours on end without feeling aches and pains.
|
|
|
| Is the top of the computer
screen at about eye level or slightly lower?
If no, and neck/shoulder discomfort
is a problem, adjust the height of the monitor accordingly (ensure that
the monitor is on a stable surface)
|
|
|
Are the characters on the
monitor easy to read?
If no, and eyestrain/headaches
are a problem, consider the following:
-
adjust the contrast/brightness levels
on the monitor
-
check distance from the monitor (should
be about arm's length)
-
check for sources of direct or reflected
glare
-
check the level of overall illumination
in the area
-
adjust font size, screen colours
