Prolonged Active Ergonomic Sitting: Change your posture
In his book on lower back disorders, Professor McGill recommends using an ergonomic chair, pointing out that such a chair must be used properly. Changing posture as frequently as every ten minutes, allows the tissue loads to migrate, thereby minimising the risk of any single tissue`s accumulating micro-trauma. Even if you don’t get up from your chair, moving position or even just fidgeting can help.
