An elegant mechanical concept
Jean Dubousset’s model describes the area within which an individual can maintain upright posture with limited compensatory effort. Moving farther from that efficient zone can require more muscular and postural compensation.
From concept to measurement
Research groups have attempted to quantify the idea using centre-of-pressure data, motion analysis and muscle activity. This makes the concept experimentally testable rather than purely descriptive.
A useful distinction
Global posture is not just an image of alignment. It also concerns how much mechanical and neuromuscular effort is required to maintain that alignment.
