2. DEFINITON OF POSTURE
The word "posture" comes from the Latin verb
"ponere" which is defined as "to put or place."
The general concept of human posture refers to "the
carriage of the body as a whole, the attitude of the
body, or the position of the limbs (the arms and legs).
Sometimes these injuries are referred to as
“Cumulative Trauma Disorders” (CTDs), “Repetitive
Strain Injuries” (RSIs) or Musculo Skeletal
Disorders(MSDs).
3. ERGONOMICS
Ergonomics literally means “the laws of work”.
OSHA defines ergonomics as the science of “designing
the job to fit the worker, instead of forcing the worker
to fit the job.”
4. AM I AT RISK FOR A MSD
Do you????
Perform frequent repetitive motions?
Bend at the waist or twist when lifting objects?
Lift push or pull objects throughout the day?
Sometimes use the wrong tool for the job?
Grasp tools with your fingers?
Forget to take breaks while working?
Feel like you are under stress?
Have to stretch to reach your work?
Forget to adjust your work area to fit your task?
The more you answered “yes”, the greater your
risk
5. RISK FACTORS THAT LEAD TO MSD
Awkward posture
Static loading or sustained exertion
Contact stress
Force
Vibration
Repetition of same motion for several hours/day
Length of tasks without breaks
Insufficient rest time
Psychosocial stress
6. SOCIAL AFFECT
Decrease Health & Quality of life
Loss of self worth and fear of future
Psychosocial consequences, e.g.,
anxiety, stress & depression
Decrease Community involvement
Decrease Recreational activities
7. ECONOMIC AFFECT
Lost wages
Absenteeism (Mean 18 days)
Medical costs ($ 7000-30,000 per
person)
Recruiting and training new staff
Retraining injured workers
Decrease Productivity & quality
Compensation
8. SYMPTOMS OF MSDS
Discomfort Numbness
LossTingling
of strength
Pain
Swelling
Reduced range of motion
Fatigue
Stiffness
Aching
9. WHAT ARE THE BENEFITS OF ERGONOMICS?
Reduction of work-related injuries
Increased worker productivity
Increased work quality
Reduced absenteeism
Increased morale
Ergonomics provides a win-win
situation….on and off the job
10. PREVENTIONS
They are preventable and reversible if identified
early.
The treatment depends on the stage of MSD.
If the condition cannot be reversed, treatment
can turn into a pain management situation.
The individual plays a large role in
preventing MSD’s.
17. Action to Take
• Check the distance of the monitor (22-26”).• Check the side-to-side position of the monito
Correct head and neck position
18. Lower
Back
Incorrect lower back position
When you sit down the inward curve in your lower back flattens,
this places pressure in the spine.
19. Actions to Take
• Get a footrest if you need one .
• If you need more support in the small of your back,
try using a lumbar support.
Correct lower back
position
20. Legs and Knees
Incorrect leg and knee position
What can happen
Pressure can build up under thighs and behind knees if your chair in not
adjusted properly.
22. EXERCISES FOR THE OFFICE
• One of the biggest injury risk factors is static posture
• Try to spend at least 5 minutes every hour away from your computer
• Remember to ONLY stretch to the point of mild tension
• Try to incorporate the stretches into your daily routine
Hand Exercises
Tightly clench your hand into a fist and release, fanning out the fingers. Repeat 3 times
23. CERVICAL STRETCH
Seated position
1 hand on contralateral
upper trapezius
1 hand on temporal/occipital
lobe
Gently apply pressure to
laterally flex & flexion
24. CERVICAL ROTATION STRETCH
Seated position
1 hand on contralateral
upper trapezius
1 hand on mandible
Gently apply pressure
to rotate head
25. CHIN TUCKS
If you are having neck pain or headaches, try tucking your chin
back as far as it will go, keeping your eyes parallel to the floor.
Do 10 repetitions slowly, without holding the stretch, every 2 hours
if you are having neck pain.
26. Poor posture
Normal load on weak or
unprepared back
Fatigue
Improper posture/ chronic
malpositioning
Lack of exercise, poor
physical conditioning
Weight control problems
27. USE CORRECT POSTURE!
Most common cause of low back pain is poor posture.
Find your correct standing posture by squeezing your
buttocks, pulling your “pits to your hips”, and
tucking in your chin.
Maintain correct seated posture using a lumbar roll.
Take frequent standing breaks top bend backward
5-6 repetitions, every hour if you have low back pain.
28. USE CORRECT POSTURE (CONT.)
If you have pain while sleeping, try using pillows
for support and a roll around your waist.
30. GETTING OUT OF BED
When getting in and out of
bed, always roll through
your side with knees
together. Use your arms
to push yourself up or
lower your self down as
your legs swing off/on the
bed.
32. LOW BACK EXTENSION
EXERCISES
Prone, or lying on your stomach on the floor or bed, is the best position
in which to do extension exercises. If you have no place to lie down (ie
– you are out shopping), then do the exercise standing.
33. LOW BACK FLEXION EXERCISES
Bring your knees to your chest slowly, then lower your feet back
down to the ground. Do 10 repetitions pulling your knees a little
further towards your chest with each repetition.
If you are under the age of 65, try back extension exercises first.
If this aggravates your condition, then do a trial of flexion
exercises.

38. ALTERNATE PRONE LEG
EXTENSION
Alternate prone leg extension
Aerobic conditioning
39. BREAKS IDEAS
Eye breaks - blink to moisten eyes every 5-10 minutes.
Every 15 minutes or so look away from the screen to
distant part of room.
Micro-breaks - between burst of activity rest the hands,
neck and shoulders in a relaxed straight posture.
Rest breaks - every 30-60 minutes take a brief 5-minute
break and engage in another activity.
Exercise breaks - every 1-2 hours do gentle stretching
exercises
40. STRETCHES & BREAKS
Static positions are your enemy!
Whenever you think of it, change position
Small frequent stretches go a long way in
preventing MSD’s.
