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? MSD MusculoSkeletal Disorders acmephysiotherapy.webs.com

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 pain Neck pain Carpel tunnel syndrome Trigger finger Tennis 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. acmephysiotherapy.webs.com

BACK PAIN PREVENTION Review your Work Area Ergonomic Rule #1 Work Comfortably! If most of your work is done in an office continueIf most of your work is done outside of an office continue

Minimize Awkward Postures Use “Neutral Posture” at the Computer & Other Equipment Next

Neutral posture: Back supported by the chair back Ears, Shoulders, Elbows, Hips vertically aligned Elbows, hips, knees bent at near-right angles (90 o – 105 o ) Feet flat on the floor or footrest The basic neutral position should be utilized a majority of the time. BASIC NEUTRAL Next

STRETCHES & BREAKS Solutions 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 acmephysiotherapy.webs.com

Desks Work Surface Depth Location of Frequently Used Devices Should be Located in Repetitive Access Zone Recommended Zones for Workplace Components acmephysiotherapy.webs.com

Office Ergonomics - The right equipment, the right place MOUSE POSITION NO! Mouse should be close to the keyboard and the same height or slightly higher Locate the mouse to avoid reaching acmephysiotherapy.webs.com

AVOID LONG DURATION OF SAME TASK acmephysiotherapy.webs.com 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 (8 o - 10 o ) Back 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 10 o - 20 o into the chair's backrest and put your feet out in front of you. Lower 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 Body Position Next 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 Laptop Computers Next Good ergonomic postures are difficult with a laptop
