Types of Problems
Head and neckShoulders and Upper armsBacks - ~85% of people at one timeWrists and HandsOther issues not caused by, but
affected by work activities
11
Caveat Ergo
Other possible causes of problems:• Hobbies outside of work• Medical conditions (diabetes,
pregnancy)• Medications• Second/Third jobs• Age-related disorders
A pain in the wrist isn’t always Carpal Tunnel!
12
Solutions – Basic Principles
Design ergonomics into any jobPre-planning is the best course of
actionTHERE IS NO “ONE SIZE FITS ALL”It’s not just the furniture! Habits
must also change

Solutions
Environment affects behavior Movement is criticalMinimize extreme posturesAvoid contact stressTake breaks!

Solutions – Basic Principles
Minimize extreme postures≥ 90° angles in knees, hips, elbowsAvoid contact stressAdjust what you canImproviseTake breaks!

Solutions
16
Solutions
Chairs:• While standing, seat at knee level • Feet flat on floor (foot board)• Room between chair edge and knees• Backrest supports lower back curve• Shoulders upright, not hunched or low• Arms rest at sides, 90° angle at
elbows17
Solutions
Work Surface• Elbow height• Adequate leg room• Adjustable keyboard trays• Store supplies at work surface level (don’t bend)
18
SolutionsMonitor• Directly in front of you• Approximately arm’s length
away• No squinting required• Top of monitor even with
eyebrows
19
SolutionsKeyboard
• Directly in front of you (“J”)• Negative tilt• Do not use keyboard
“feet”• Neutral, straight wrists• Don’t rest on wrist rests
20
Solutions
Mousing• Hand in straight line with forearm• Do not bend wrist• Mouse should same height as and
directly adjacent to keyboard
21
Arranging Your Workstation
Accessories• Headset or shoulder rest• Document holder – adjacent to
monitor• Foot rest• Monitor Arm• Mice, Keyboards
Advice• Turn whole body, don’t twist• Breaks – 1 min./30 min. or 20/20/20 22
Solutions

Laptop Use
Same requirementsDocking StationsUse laptop as monitor (stand)Aux. keyboard and mouse
24
Standing vs. Sitting
Keyboard at elbow heightTop of monitor even with tops of
eyebrowsAnti-fatigue mat to stand onSolid foot rest?Alternate standing with sitting
25
Lighting the Way
Different tasks require different levels of light
“Old eyes” need more lightComputer glassesOne source of overhead lights Task lighting avoids glare, provides
additional light when/where needed
26
Solutions
Changing habits is also very important
PostureBreaks – stretches?Arrangement of work
stationFollowing suggestions
27
Remember that…The best solutions the
most expensiveGadgets, bells & whistles
can’t substitute for training and good practices
The best way to prevent problems is to design them out at the beginning
Be creative in finding solutions
28
A Word or Two about Backs
Remember what we said about 85% of the US population reporting back pain?
There are many causes; some preventable, some not
There are things you can do to prevent or limit back problems
Proper Lifting Techniques
Solutions
Carrying• Carry in the “Power Zone”• Redesign process to limit/eliminate need to
carry• Reduce bulk/weight of materials to be carried• Reduce distance
SolutionsPushing/Pulling
• Know the route• Push rather than pull• Minimize weight• Stay close to load, bend knees• Adjustable handles to keep grip within Power
Zone• Ensure good visibility• Avoid twisting/turning
Assistive Devices
These can be helpful, but must be combined with proper body positioning, etc.
