What are the risks of ignoring ergonomic principles? An MSD is an illness or injury that affects one or more parts of the musculoskeletal system Bones MSD 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. MusculoSkeletal Disorders
SYMPTOMS of MSDs DiscomfortNumbness Tingling Loss of strength Swelling Reduced range of motion Fatigue Pain Stiffness Aching

Office Ergonomics- The right equipment, the right place Use a good CHAIR Backrest is provides good lower back support Arms adjustable Front edge of seat pan curves down Height adjustable On rollers Seat pan adjustable horizontally and tilts Five feet for base-most stable
Office Ergonomics- The right equipment, the right place KEYBOARD STYLES A variety of styles are available. Choose one that is comfortable for you.
Keyboard holders should Office Ergonomics- The right equipment, the right place KEYBOARD HOLDER Tilt Provide wrist rests (rest palms not wrist) Provide space for a mouse
Office Ergonomics- The right equipment, the right place MOUSE HOLDERS Mouse trays or mouse holders can bring a mouse to a better position
Office Ergonomics- The right equipment, the right place MOUSE STYLES Choose a style comfortable for your hand and fingers
Office Ergonomics- The right equipment, the right place Everyone needs a relaxed, neutral position DO WHAT S COMFORTABLE FOR YOUR BODY! Monitor at or below eye level Wrists straight Back supported Forearms and thighs parallel to the floor Forearms supported Feet flat on the floor
Mouse should be close to the keyboard and the same height or NO! slightly higher Locate the mouse to avoid reaching Office Ergonomics- The right equipment, the right place MOUSE POSITION
Office Ergonomics- The right equipment, the right place Phone PLACEMENT Should be different for right and left handers You should not have to twist and reach across your body every time you answer the phone. Many people need to spend a lot of time on the phone, and must often do other tasks at the same time This creates a lot of stress for neck and shoulder muscles Consider a head set if you spend a lot of time on the phone, especially if you do other tasks at the same time
