Ergonomics is crucial for preventing injuries and illnesses related to overexertion or repetitive motion, costing billions annually. Learn about Musculoskeletal Disorders (MSDs), risk factors, signals, and ways to control and reduce risks in order to promote a healthier work environment.

Ergonomics • Ergonomics recognized as major factor in work place health • One-third of injuries/illnesses stem from over exertion and/or repetitive motion • Cost-$20 billion
Ergonomics • Improving the fit between the body and an activity • Adapting the environment & using techniques to prevent injuries • ID/reduce risk of MSD’s
Musculoskeletal Disorders (MSD’s) • Associated with repetitive strain or damage to muscles, tendons, nerves, and joints • Signals: • Discomfort, swelling, aching, tingling, numbness • Signals come & go, may become constant. • Most frequently affect back & wrists • Left untreated, may limit joint’s motion
Personal Risk Factors • Associated with ADL • Overweight • Under fit • Previous injuries • More than one risk factor • More often exposed>risk of an MSD
Work Related Risk Factors • Posture • Slouch, twist, reach too far • Repetition • Using same muscles repeatedly • Environment • Vibration, temperature, lighting • Force • Forceful exertion, grip, pull, push, lift • Duration • The longer the duration, the higher the risk • Recovery • Moving body in same way for a long time
Controlling the Risk • Id & assess risk • How much contact • Reduce risk • Plan on working toward reducing risk factors • Monitor & communicate
Reducing the Risk • Take responsibility for reducing risk • Apply ergonomic principles both at work and at home • Correct posture problems • Stay near neutral position • Simple adjustments to work area
