It provides insight as to why models for ‘idealised posture’ (plumb line aligned, or kept straight using ‘straight back’ thinking, 90 degree thinking, middle-of-feet balance, etc) disrupt postural elevation. This is a highly controversial issue that Power Ergonomics addresses not least because it is easy to demonstrate that many people suffer from lower back pain and other musculoskeletal disorders BECAUSE they practice idealised postures. As such Power Ergonomics is the first approach to emphasise the need to consciously eliminate confounding thinking, i.e. applying models and ideas that disrupt elevation.
