What is “Ergonomics”?
Ergonomics is the scientific study of human work.
Ergonomic principals adapt work to a specific person by designing tasks & tools or equipment to fit the individual to prevent injuries to the musculoskeletal system. acmephysiotherapy.webs.com
An “MSD” is an illness or injury that affects one or more parts of the musculoskeletal system
Bones Muscles Tendons Ligaments Cartilage Nerves Blood vessels
Other common terms for “MSDs”are: Cumulative trauma disorder (CTD’s) Repetitive strain injures (RSI’s) Repetitive motion injuries (RMI’s)When not diagnosed and treated these can cause
inconvenience permanent pain and disability.
What are the risks of ignoring ergonomic principles?

What are MSD’S?
MSD’s are injuries caused by sustained exposure to stressors or repetitive motion ,may affect muscles, tendons, ligaments, bones, circulation, or nerves for example- working long hours on computer.
Some are:Back painNeck painCarpel tunnel syndromeTrigger fingerTennis elbow
Back pain
Most common work-related injuries Two types of situations cause back pain while on the job:•Non-accidental injury-•Pain result of normal activities and requirements of the task. Poor body mechanics (such as slouching in an office chair)
Major contributors to these injuries.
• prolonged activity, • repetitive motions• fatigue This may occur from sitting in an office
chair or standing for too long in one position
Accidental injury results-
when an unexpected event triggers injury during the task. A load that slips or shifts as it is being lifted slip fall hitting one’s head on a cabinet door accidents can jolt the neck, back and other
joints with resulting muscle strain or tearing of soft tissue in the back.
ARE MSD’S PREVENTABLE?
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.
Exercise plays a large role in preventing MSD’s.

BACK PAIN PREVENTION
• Review your Work Area
•Ergonomic Rule #1
Work Comfortably!If most of your work is done in an office continue If most of your work is done outside of an office continue
Minimize Minimize Awkward Awkward PosturesPostures
Use “Neutral Posture” at the Computer & Other Use “Neutral Posture” at the Computer & Other EquipmentEquipment
Next
Neutral posture: • Back supported by the chair back• Ears, Shoulders, Elbows, Hips vertically aligned• Elbows, hips, knees bent at near-right angles (90o – 105o)• Feet flat on the floor or footrest
The basic neutral position should be utilized a majority of the time .

STRETCHES & BREAKSSolutions
Static positions are your enemy!
Whenever you think of it, change position
Small frequent stretches go a long way in preventing MSD’s.
Office Ergonomics- The right equipment, the right place
Use a good CHAIR
Front edge of seat pan curves down
Five feet for base-most stable
Height adjustable On rollers
Seat pan adjustable horizontally and tilts
Backrest is provides good lower back support
Arms adjustable

MOUSE POSITION
NO!
Mouse should be close to the keyboard and the same height or slightly higher

AVOID LONG DURATION OF SAME TASK

Our bodies are designed to do work. But the result on the body of doing a repetitive task for 2 hours verses 6
hours straight is very different.
Solutions
Forward tilt posture: Raise the chair height a few inches and tilt the front downward slightly (8o - 10o)
Back ReliefBack Relief
Opens hip angle allowing legs to support some weight.
Not recommended if you have knee or foot problems.
May be used occasionally throughout the day by most people; but is not recommended for long periods at a time. Next
Reclining posture: Lean back 10o - 20o into the chair's backrest and put your feet out in front of you.
Lower Body ReliefLower Body Relief
Opens hip and knee angles to help relax back muscles and promotes blood circulation. Leaning back too far can result in an awkward neck posture.
May be used occasionally throughout the day by most people; but not recommended for long periods at a time.
Next
Adjust your chair to achieve a neutral position – keep trying, it is an ongoing process!
Fix (or have fixed) a malfunctioning chair Use a lumbar cushion for additional support or if chair lacks adequate
back support or seat is too deep Pad armrests that are hard or that have square edges Remove armrests if they contribute to awkward postures Use a foot rest or keyboard platform to help achieve neutral position if
necessary
Minimize Awkward Minimize Awkward Body PositionBody Position

Adjust Your Chair
Full-time users: Use separate keyboard and mouse Position screen for optimal viewing
Occasional users: Position laptop for neutral wrist position Angle screen to minimize bending at the back & neck Modify your position regularly, especially if feeling discomfort Limit time spent on a laptop computer if you can’t relieve awkward
postures

Who can go to physiotherapist?
1.Individuals with pain receive physio to improve function and structural correction.
2.Individuals without any dysfunction receive physio to improve health and wellness and to prevent impairments.
Questions?Questions?
Am I at risk for a MSD?
Do you
…perform frequent repetitive motions?…bend at the waist or twist when lifting objects?…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.acmephysiotherapy.webs.com
