Ergonomics Assignment

(esp. of workplace design) Intended to provide optimum comfort and to avoid stress or injury. er·go·nom·ic /rgnämik/Adjective Ergonomics (or human factors) is the scientific discipline concerned with the understanding of the interactions among humans and other elements of a system, and the profession that applies theoretical principles, data and methods to design in order to optimize human well being and overall system performance.

Practitioners of ergonomics, ergonomists, contribute to the planning, design and evaluation of tasks, jobs, products, organizations, environments and systems in order to make them compatible with the needs, abilities and limitations of people. How to Achieve an Ergonomic Workplace You start, change the height of your seat until feet are planted on the ground. The angle of your knees should always be 90 degrees or greater. The back of the chair should be completely strait (90 degrees) or slightly obtuse. Your elbows should also be at 90 degrees, causing your wrist to be strait. Remember to always support the small of your back. Most modern office chairs have a 'bulge' to give lumber support to your lower back, but it needs to be in the right place. You may have to raise or lower the back of the chair. Remember to take 10-15 minute breaks every hour. Stretch. Siting in a rigid position for a long span of time is not at all good for your muscles. Take some time to do non routine activities. Such as leaving to copying something, or checking the fax machine. This will help minimizes and relieve work stress. Keeping your back strait, and your shoulders relaxed but not slouched will prevent muscle strain. Because room lights can leave a glare on computer screens, which causes eye fatigue, you should limit the amount of unneeded room light. But, because insignificant light is also bad for your eyes, small lamps concentrated on your working desk are a great idea. The monitor should always be at least 20 inches from your face. . . . . http://www.ergonomics-info.com/ergonomic-exercises.html These are some great stretches to use while working on a computer. Repetitive strain injuries (RSIs) are "injuries of the musculoskeletal and nervous systems that may be caused by repetitive tasks, forceful exertions, vibrations, mechanical compression (pressing against hard surfaces), or sustained or awkward positions". RSI is also known as cumulative trauma disorders, repetitive stress injuries, repetitive motion injuries or disorders, musculoskeletal disorders, and [occupational] overuse syndromes. Repetitive strain injury (RSI) is a syndrome incorporating several discrete conditions associated with activity-related arm pain such as edema, tendinitis, carpal tunnel syndrome, cubital tunnel syndrome, thoracic outlet syndrome, stenosing tenosynovitis, intersection syndrome, golfer's elbow or medial epicondylitis, tennis elbow or lateral epicondylitis, radial tunnel syndrome, and focal dystonia.

Why Do We Need It? Without Ergonomics you could potentially inflict on yourself a Repetitive strain injury.
What's that you say? Fancy Definition Non-Fancy Definition This basically means, getting an injury from doing an action over and over again in a not very efficient or healthy position. These injuries can lead to permanent problems (Wikipedia) I MR. TOTH
