Backache in the office?

One in four European workers is forced to deal with back pain (source of the European Foundation for the Improvement of Living and Working Conditions). Back pain in the vast majority of cases affects the cervical and lumbar area (most exposed to stresses) and in a lesser way the dorsal area.In general Causes and origins of the maldischiena are topics that may affect different medical disciplines as an example and not exhaustive orthopedics, neurology, physiotherapy, surgery, psychiatry areas where it is good to turn to treat back pain.

Prevent back pain in the office

Very often those who live seated for work are struck by back pain, the pain can 'arise from both a bad posture and an inappropriate session, which can' generate itself harmful postural attitudes.The daily protracted of these postural attitudes together with the the static nature of the sitting position results in a progressive loss of the elasticity of the ligaments and intervertebral discs and a loss of power and tone of the muscles. With the passage of time, ligaments and discs can no longer adequately cushion the stresses of daily life. Intervertebral spaces are reduced, pressure on the disc is increased and pains and discomfort begin to appear, which are the premise of inflammation that leads to acute and sub-acute lumbago and to lumbosacralgia.

How to sit

Head: Do not extend the neck and head forward, position the seat in relation to the work surface in such a way as to allow alignment between head and neck.

Shoulders: Relaxed shoulders with elbows on the armrests or at the desk. The use of armrests allows adequate support to the upper back and shoulders, so as to reduce fatigue. In case of work in the video terminal The forearm and the wrist must remain in line while working on the keyboard; therefore, the forearms must be slightly higher than the keyboard. sit at the desk so that your forearms are parallel to the work surface: if your elbows are not at right angles, adjust your chair height.

Back: the back must rest on the back such that the spine is well aligned and the curves of the spine must preserve the physiological widths. The back must be supported by the backrest. In particular the sacrum must be supported by the back and the lumbar lordosis well maintained.

Legs: In sitting position the inclination between thigh and leg should approximately form an angle of 90 ° (If the session is too high the hips will be higher than the knees pushing the lumbar stretch forward) check if you can easily slide your fingers under the thigh following the edge of the chair: if it is too tight, it is necessary to support the feet with an adjustable footrest. Feet: well supported on the ground.

Most of the seats do not allow you to sit properly, the professional ergonomic seats.

Main distinctive features for professional ergonomic office chairs-

 Adjustable Height - Height adjustment by gas elevation. The seat height range is usually between 42 and 56 cm, so as to satisfy the anthropomorphic characteristics of the 90 percentile of the population. In the interval described most of the users are able to position the feet well on the ground with the thighs and the horizontal arms, parallel to the work surface. Seat width and depth -The measurement range in relation to the seat width suitable to sufficiently support the majority of users is between 42 and 52 cm. approx. The depth of the seat should be such that the user, by sticking his / her back to the back, will find himself with a free space between the back of his knees and the seat of about 5 10 cm. Forwards or backwards the seat angle should be adjustable. Lumbar support - Adjustable both in height and depth to ensure maximum support for the dorsal curve in the lumbar region. Backrest - It should be anatomically adequate to support the natural curve of the spine, if it is monoblock with the seat must be equipped with a system of blocking the oscillation in more positions and backstroke of the back (antishock). In models with backrest separated from the seat the possibility of adjusting both the height and the inclination of the backrest is of considerable importance. Cuffs - The aid of the armrests to allow correct posture of the upper limbs in working position is expressed by the 3D armrests with height, depth and inclination of the same.Mechanics: Synchronized movement of the seat and back help to maintain the right tilt ratio between the trunk and the sacral base in a sitting position.
