Sitting and standing are the most common work positions, which tend to be accompanied by emersion of various problems of the locomotive apparatus. But it is not only sitting and standing which lead to emersion of possible problems. Primarily the way how the particular person is sitting (or standing) and how much time he/she spends in this position.
While standing, majority of the bodyweight is put onto the lower extremities. In comparison with sitting, this position is unstable. The body center of gravity is high above the supporting area, which is relatively small. Work tasks performed while standing cannot be done in the ideal upright position, because the body center of gravity is shifted due to the work activity and in relation to its character. The common STAND while working can be then characterized as "weak or collapsed" body posture.
While sitting, the spine supports the entire upper body and majority of weight is transferred onto the ischial bone and hip joints. The lower extremities are only passively set on the floor and partially ensure the stability of the body. In most cases happens that the pelvis is tilted back (retroversion), through which the spine loses its natural curving. Kyphosis starts to settle in with a bad body posture and straining of the spine in its entire length. In addition, during "a standard sitting position", the upper body muscles do not work fully and thus the pressure on the vertebrae and the inter-vertebral discs increases. The common SITTING POSITION at work can be also characterized as "weak or collapsed" body posture.
Proper ergonomy of these positions is a solution. It should be done so there will be no straining of individual body parts. We speak about corrected / active sitting (standing) position and compensative movement regime.
Our practical seminars, consultations, rehabilitation methods and ergonometric tools comprehensively address this issue!
