shoulder/neck pain?
YES / NO
2. While typing, do you have any pain in forearms/wrists/hands?
YES / NO
3. While sitting for a long period of time, do you have any pain in your
legs and/or feet?
YES / NO
4. Do you have symptoms of eye strain like a burning sensation in the
eyes, blurred vision, irritated eyes, or headache?
YES / NO
6. Is your work environment frequently too cold or too hot?
YES / NO
7. Do you work for hours without taking task breaks?
YES / NO
8. Do you work for hours without performing stretching exercises?
YES / NO
If you answered yes to any of the above questions,
please continue with the checklist.
HEAD/NECK
1. Is your head facing straight and eyes looking forward at your
work?
YES / NO
Your head should be straight and your eyes looking
forward when using your monitor. You should not have to turn your head
frequently for long periods to do any of your work.
2. Do you lean into the screen with your head and neck, i.e. are your ears
forward of your shoulders while working?
YES / NO
If your head is always leaned forward this causes the muscles of the
neck and upper back to work overtime and can cause upper back pain, neck pain
and headaches.
3. Are you able to reach the objects at your workstation
(keyboard, mouse, phone) without reaching (keeping your arms and elbows
forward of your body without support), especially where the reaching
is held for long durations?
YES / NO
Keep objects you use frequently within easy reach (about
12 inches). Reaching forward without support makes the neck and upper back
muscles work overtime and can cause upper back pain, neck pain and
headaches.
EYES/OFFICE LIGHTING
1. Is the top/middle of your monitor screen at eye level?
YES / NO
The monitor should be at a height that does not make you tilt
your head up or down. You should be able to adjust the height,
fore/aft distance, tilt and rotation of the monitor.
2. Is your monitor directly in front of you (not off to one side)?
Is the depth of the worksurface appropriate; can the
monitor (flat screens are certainly a big help) and keyboard be placed directly
in front of you and not off to the side, i.e. work orientation parallel to
the plane of your upper body?
YES / NO
Your monitor should be directly in front of you so you do not
have to twist your body or turn/tilt your head. It should be
as far away as can be clearly read.
3. Do you use a document holder? Are you looking back and forth
from the monitor to a document that is placed flat on your desk?
YES / NO
A document holder prevents a head down position which
puts much stress on the muscles of the neck. The height, distance and
angle of the holder should be adjustable.
4. Do you have glare on your screen?
YES / NO
Reduce light from outside or overhead; indirect light rather than
overhead flourescent bulbs is better. Louvers or diffusers on overhead
lights can be a big help. An anti-glare screen for the monitor
helps as well. A matte finish on your work surface can help
prevent glare. Windows/doors should ideally be at right angles
to your monitor.
5. Do windows have curtains, drapes or blinds to block light
where glare from that source is a problem?
YES / NO
Being able to adjust the outside light levels is a must. Outside light
changes in position and intensity throughout the day.
6. Do you wear bifocals?
YES / NO
If you wear bifocals, you may need to lower
your monitor. Monitor platforms may be used to adjust screen
height. Combination type lens may be very helpful. Speak to your
optometrist about this.
7. Do you wear contacts?
YES / NO
Use rewetting drops while you are working at the computer.
8. Do you include stretching and eye exercises during your
work day?
YES / NO
Use the "20/20 rule" --- every twenty minutes, look
twenty feet away for twenty seconds. Move head and body
periodically for comfort.
FOREARMS/WRISTS/HANDS
1. Does your chair have arm rests?
YES / NO
Arm rests, when used, should comfortably support the forearms
but should not interfere with arm motion.
Armrest padding and adjustable height and lateral positions are helpful.
2. Do you have a wrist rest?
YES / NO
A padded wrist rest may help support the wrists/palms during rest
periods.
3. Are your elbows bent at a 90 degree angle? Are your
forearms about parallel with the floor?
YES / NO
You should be able to sit up straight, with your shoulders
relaxed and arms and elbows along the side of your body and bend your elbows to
90 degrees and keep you forearms parallel with the floor.
4. Is your desk height comfortable?
YES / NO
Your chair with armrests should be able to roll close enough to
the desk to allow proper body positioning. Desk height should be 29" - 30"
(keyboard tray should be about 3" lower).
5. Is your keyboard at a comfortable height and angle?
YES / NO
Hands should be in a straight line with the forearms, wrist and
hands not flexed down towards the palm and not extended up,
nor bent towards the little finger, nor bent towards the thumb.
6. Is the shape and button activation of the mouse comfortable and
easy to operate for the person?
YES / NO
For an interesting mouse see
Zero Tension Mouse
7. Is your mouse placed next to the keyboard?
YES / NO
You should be able to reach and operate the mouse without
extended, long duration, or repetitive reaching and with the
shoulders, arms and wrists in a neutral posture.
Keep the mouse as close as possible to you.
THIGHS/LEGS/FEET
1. Are your hips and back resting comfortably against the back
of the chair?
YES / NO
Do not sit on the edge of your chair and lean forward. Your
ears/shoulders/hips should be in a vertical line. The forward posture
can cause headaches, neck pain and back pain.
2. Are your feet flat on the floor?
YES / NO
Your feet should comfortably rest flat on the floor.
3. Do you have a foot rest?
YES / NO
A foot rest may help increase circulation in legs, relieve
stress on back and keep legs at a comfortable angle. A height
and tilt adjustment is recommended.
4. Are your thighs parallel to the floor?
YES / NO
The knees can be kept level, slightly higher, or slightly lower than
the hips. Different tasks (writing vs. keyboard entry) can require
different positions. Try each position and see which works best.
5. Do you experience any uncomfortable pressure points,
obstructions, or other interferences in the lower extremities (hips, thighs,
legs, feet)?
YES / NO
You should have 2" of space between the front edge of chair to
back of knees.
6. Is the area under the desk large enough to accommodate the
thighs and any accessories, such as footrests and arm rests?
YES / NO
The desk should be high enough to allow sufficient thigh clearance.
CHAIR DESIGN FEATURES
1. Is the chair height adjustable, such that you are
able to set it at an individually comfortable height in relation
to the required work activities?
YES / NO
Sitting up straignt is a must!
2. Can you easily adjust the seat back height to provide mid
lumbar support (lower back region- small of your back)?
YES / NO
The seat back must be adjustable to the lumbar support hits the small
of the back, not the mid back or buttocks.
3. Is the seat bottom (what you sit on) of appropriate size, such
that it is deep and wide enough to comfortably accommodate the specific person?
YES / NO
You should have 2" of space between the front edge of chair to
back of knees. The seat back may adjust forward and back. The bottom
should not be too wide or too narrow.
4. Is the seat bottom comfortable and is the front well rounded
("waterfall" front edge), such that you do not experience
excess pressure on the under side of the leg due to the forward
edge?
YES / NO
A sharp edge will put pressure on the back of the thighs and
decrease circulation to the legs and feet.
5. Can you easily adjust the angle of the seat bottom so that it can
slope downward (keeping knees below hip level) or upward (keeping
knees above hip level)?
YES / NO
The knees can be kept level, slightly higher, or slightly lower than
the hips. Different tasks (writing vs. keyboard entry) can require
different positions. Try each position and see which works best.
FATIGUE CONTROL
1. Are you allowed to take rest pauses or breaks from
tasks that require long duration or repetitive postures, forces,
keying or mousing activities?
YES / NO
Breaks should be taken at least every 60 minutes. Get up from your chair
and perform a few exercises.
For exercises to do during your workday see
RSI Exercises and
Workplace Exercises
WORKPLACE ENVIRONMENT
Temperature
1. Are you comfortable with the ambient temperatures?
YES / NO
Keep a sweater handy if the temperature is too cool.
2. Are you comfortable with the temperatures of
any equipment or surfaces you must contact?
If this is an issue, it must be corrected.
YES / NO
Vibration
1. Do you experience any uncomfortable equipment
vibration (e.g. wobble from an unstable keyboard tray)?
YES / NO
Make sure all surfaces are flat and any wobble in chair, worksurface or
keyboard is removed. Vibration cause significant discomfort over
time.
Noise
1. Are sound levels at comfortable levels (equipment noise), allowing
conversation and other communications without significant effort?
YES / NO
Diminish equipment noise by making sure all surfaces are stable

shocks?
YES / NO
Report this at once.
Psycho-Social Issues
Psycho-social issue are important. Having good communication
with your supervisors and staff is very important to decreasing
stress in the workplace. Providing and receiving proper training on all
types of equipment and software is critical as well.
