Hi there, I think this question has been asked of another but no reply so here goes - What are the 5 areas of static posture, and what would be considered 'ideal' in these areas?

Static Postures

Static postures (or "static loading") refer to physical exertion in which the same posture or position is held throughout the exertion. These types of exertions put increased loads or forces on the muscles and tendons, which contributes to fatigue. This occurs because not moving impedes the flow of blood that is needed to bring nutrients to the muscles and to carry away the waste products of muscle metabolism. Examples of static postures include gripping tools that cannot be put down, holding the arms out or up to perform tasks, or standing in one place for prolonged periods.

The effects on the body from doing tasks that require long reaches are exacerbated where the reaches must be maintained for more than a very few seconds. Holding extreme postures places very high static loads on the body, resulting in rapid fatigue. Not only do the static postures add to the muscular effort required to do the task, but the lack of motion impedes the blood flow that is necessary for tissue recovery.

The constricted blood flow reduces the supply of nutrients to the muscles and the removal of acids and other waste products away from the tissues. Reduced blood flow also slows down delivery of oxygen to the muscles.

The longer or more frequently static loading occurs, the greater the risk of injury due to overuse of muscles, joints and other tissues.

* Doing extensive repair work when the automobile is overhead on a vehicle lift
* Holding out the arm to use a mouse that is on a surface more than 15 inches from the body because the keyboard tray is not big enough to hold the mouse

Ergonomic equipment eliminates these stressful postures.
