Ergonomics Ergonomic
Ergonomics (or human factors) is the scientific
discipline concerned with the understanding
of interactions among humans and other
elements of a system, in order to optimize
human well-being and overall system
performance.

Divisions of Ergonomics
Physical
Physical ergonomics is concerned with human
anatomical, anthropometric, physiological
and biomechanical characteristics as they
relate to physical activity.
(Relevant topics include working postures,
materials handling, repetitive movements,
work related musculoskeletal disorders,
workplace layout, safety and health.)

Cognitive
Cognitive ergonomics is concerned withmental processes, such as perception,memory, reasoning, and motor response, asthey affect interactions among humans and
other elements of a system. (Relevant topicsinclude mental workload, decision-making,skilled performance, human-computerinteraction, human reliability, work stress andtraining as these may relate to human-systemdesign.)

A musculoskeletal disorder is a condition
where a part of musculoskeletal system is
injured overtime.
The disorder occurs when the body part is
called on to work harder, stretch farther,
impact more directly or otherwise functionat a greater level then it is prepared for.
The immediate impact may be minute, but
when it occurs repeatedly the constanttrauma cause damage.
