WELCOME TO COMPUTER ERGONOMICS TRAINING WHY ARE WE HERE? Annual injuries • 1,800,000 workers injured • 600,000 require time off work TRAINING OBJECTIVES • • • • Identify optimal body position Identify workstation adjustments Demonstrate exercises Understand roles and responsibilities ERGONOMICS IT’S GREEK TO ME! ERGONOMICS IT’S GREEK TO ME! ERGOS = WORK NOMOS = NATURAL LAWS ERGONOMICS • The study of the relationship of the individual, the material, the equipment and the environment • Addresses human performance and well being in relation to the job or activity.

Comfort Increase productivity Increase quality Avoid injury RULES OF BODY MECHANICS • Use each joint to its best mechanical advantage. • Avoid static or sustained positions. • Use your body symmetrically. • Keep extremities close to vertical axis of body. • Avoid tight grasp. • Use stronger/larger joints when possible. • Respect pain! NEUTRAL POSTURES • mid-range • strength • comfort RISK FACTORS • • • • • • • Static posture Awkward posture Repetition Force Pressure (physical contact) Vibration Temperature extremes PHYSIOLOGY OF DISCOMFORT • Discomfort • Fatigue • Lack of stamina IMPAIRED CIRCULATION • • • • • • • Static muscles - particularly under load Awkward postures Physical contact Vibration Temperature extremes Poor physical condition Illness/Disease • Smoking • Exposure to certain chemicals/gasses • Lung obstruction • Anemia PHYSIOLOGY OF COMFORT • Healthy tissue • Oxygen and nutrition • Waste product removal CUMULATIVE TRAUMA DISORDERS NERVE TENDON Carpal Tunnel Syndrome Cubital Tunnel Syndrome Tendonitis Epicondylitis Golfer’s Elbow Tennis Elbow Tenosynovitis De Quervain’s Trigger Finger Rotator Cuff Tendonitis NEUROVASCULAR Thoracic Outlet Syndrome Raynaud’s Syndrome MUSCULOSKELETAL Bursitis Back strain/sprain Neck strain/sprain OTHER Ganglion Cyst SYMPTOMS • • • • • • • Discomfort Pain Tingling Numbness Swelling Weakness Loss of dexterity WORKSTATION EXERCISES BENEFITS OF EXERCISE • • • • • Improved circulation Improved flexibility Improved muscle strength and endurance Reduced muscle fatigue Reduced stress EXERCISE GUIDELINES • Breathe while exercising • Stretch gently • Pace yourself • Move slowly and smoothly • Exercise regularly • STOP if pain occurs ROLES & RESPONSIBILITIES • Everyone • Supervisor/manager • Ergonomic Coordinator BE SAFE WORK IN COMFORT
