What is Ergonomics?
ERGO=“work”
NOMICS= “rules” or “laws”
 Ergonomics literally means “the
laws of work”

SO EXACTLY WHAT IS
ERGONOMICS?
It is study of people efficiency at their working
environment.
It is one of the definition of Ergonomics.
It is understandable that there are different
definitions because ergonomics is all about
differences

DIFFERENCES
 This are differences in
size, shape, strength and
ability of individual
workers.
This differences call for
different designs in
equipment , furniture,
Workstations and routines.

ERGONOMICS
 Ergonomics is used
in a workplace to
help prevent
repetitive and
cumulative injuries.

3 Main Ergonomic Principles:
1. Work activities should permit worker to adopt
several different healthy and safe postures.
2. Muscle forces should be done by the largest
appropriate muscle groups available
3. Work activities s/b performed with joints at
about mid-point of their ROM (esp. head,trunk,
UE)

FACTS
The average person working at a keyboard can
perform 50,000 to 200,000 keystrokes a day
Overexertion & falls are the most common
cause of workplace injury
An average of 125,000 back injuries due to
improper lifting each year.
Muscles overuse results in tiny tears in the
muscles and scarring; these contribute to
inflammation and muscle stiffness

Ergonomic Factors
Two Categories of Ergonomic Factors
1. Environmental
 Hearing
 Vision
General comfort and health
2. Physical

Environmental Factors
 Some examples of ergonomic environmental problems
are:
 Sick Building Syndrome
 Excessive noise
 Improper lighting
 Temperature extremes

Physical Stressors
Physical stressors place pressure or stress on parts
of the body:
 Joints, muscles, nerves, tendons, bones
Sometimes these injuries are referred to as
“Cumulative Trauma Disorders” (CTDs) or
“Repetitive Strain Injuries” (RSIs)

Types of Injuries
• Muscle pain
• Joint pain
• Swelling
• Numbness
• Restricted motion
• Repetitive stress injury
• Repetitive motion
injury
• Cumulative trauma
disorder
• Musculoskeletal
disorder

ERGONOMIC STRESS AREAS
Hip
Knee

Target Regions
• Back
• Upper extremities
• Lower extremities

Types of Problems or Mismatches
 Physical Size
 Endurance
 Strength
 Manipulative
 Environmental
 Cognitive

Physical Size
 Clearance
 Reach
 Equipment Size
 Personal Protective
Equipment (PPE)

Cognitive
 Machine Pacing
 Shift Work
 Morale
 Psychosocial

Musculoskeletal Disorders:
Signs and Symptoms
Decreased grip
and/or pinch
strength
Swelling
Fatigue
Loss of function
Numbness
Burning sensation
Tingling
Pain
Cramping
Stiffness

An ounce of Prevention is worth a
pound of cure !

What to do ??
a) Warm up & stretch before activities that
are repetitive, static or prolonged
b) Take frequent breaks from ANY sustained
posture every 20-30 minutes
c) Respect pain positions or stop painful
activity
d) Recognize early signs of inflammatory
process

Posture check
Increased stress, decreased circulation…

Posture
Think of posture in terms of joint position
Static and awkward postures lead to:
 Decreased movement
 Decreased circulation
 Increased stress and fatigue

Maintain Neutral Posture
a) Maintain erect position of back
& neck without shoulders relaxed
b) Position equipment & work directly in
front of and close to your major tasks
c) Avoid static positions for prolonged
time; muscles fatigue---MOVE to
circulation!

Modify Tasks
a) Alternate activities frequently; rotate
heavy &/or repetitive tasks without
lighter less repetitive ones.
b) If stress become worse REASSESS task
setup & look for alternative methods
c) Avoid repetitive or prolonged grip
activities
