Finding The Right Position

This is a very idyllic picture by a great painter who would have been a certified disaster as a physiotherapist. His lovely model at the breakfast table makes all the mistakes possible: her body is distorted, she is leaning forward, straining her neck, shoulders and arms, and so on. Hopefully there is nothing of special interest in her newspaper this morning.
This artist painted his hard-working brothers, standing and sitting at a writing desk and table, respectively. For the sake of their backs one must hope that they changed position from time to time.

For screen work you may use the classic position with everything at right angles: neck, thigh, elbows and legs, and with your feet planted solidly on the floor. The chair must be adjusted so that it will support the natural S-shape of your spine.

The reading and writing position is a variation of the classic position. It's best for your back if the seat of your chair can follow your movement forward so that there will be no pressure on the thighs and the arteries under them. A slanting tabletop will both offer better support and a better visual angle. Use your imagination - move about on your chair. Find other ways of sitting. No position is good enough to be the one and only.

Both back and seat can tilt on modern chairs. It's good for the back if you sometimes lean back and rest in this position - but not for too long on account of your neck muscles.
