The meaning and concept of correct posture: Correct posture means the balancing of body in an accurate and proper manner while sitting, standing, reading, writing or during any other action of body. The human body always have a constant battle against the force of gravity. Even while we are asleep, we change our position a number of times to avoid discomfort. This discomfort is largely caused by pressure on the soft tissues between the bony structures and the supporting parts.
