Body Postures and Work Station- Ergonomics

Introduction:

What is Ergonomics?

* 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.

* Ergonomics is an ongoing process, not a “quick fix.” Over time, changes in equipment, software, and work procedures can either enhance or undermine the ergonomics of the work environment.  Continued awareness and cooperation among responsible groups are essential to an effective ergonomics program.  It is a continuous process that must anticipate and adapt to changes in work processes and technology.

Why do we study Ergonomics in Work?

* When ergonomic principles are applied in a work environment, many workplace injuries are avoided.

* Work performance can be improved.

* Costs for medication of injuries are reduced.

Body Postures and Work Stations:

A. Body Postures:

What is posture?

Posture is a static state - 'A position of the body' or 'An attitude' (dictionary.com), 'Posture is arrested movement' (Bobath). By itself it's a word which is often qualified - defensive, poor, bad, aggressive, and happy - and is often used in related ways, with overtones of opinion towards something, sometimes with a meaning of falsehood.

What distinguishes it from 'position' is the inclusion of a mental ingredient, particularly mood or emotion; ie., posture is a 'position with attitude', so to speak. We always have a posture of some kind or another, even if the mental intention behind it is subconscious. And, of course, it is well documented that body language plays a large part in communication.

The following are some of the tasks that are prone to Ergonomic Risk- Factors:

* Awkward Postures:

Awkward postures are body positions that are uncomfortable, or put the body parts in use in a mechanical disadvantage.  Muscles and...
