Image A - example of poor posture:
- Feet in a wrong position - heels together, toes apart, which is shown by the yellow lines converging behind
- Blue points - ankle, knee, iliac, bottom and top sternum. All of these need to be on the green line
- Shortening in the lower back (red curve). Another giveaway is the abdomen protruding forward
- Sternum is inclined backwards at the top, commonly referred to as "unduly lifted chest". We would like vertical sternum placed on the green plumb line.
- The mechanism of the arm is pulled far too back, shoulders raised and shoulder blades visibly protruding at the back
- Visible shortening of the cervical spine (top red curve)
Image B - considerably better posture (although not yet perfect)
- Feet placed more appropriately
- Blue points - considerably closer to the green plumb line
- Ankles and knees extended
- Curve in the lower back considerably flattened
- Mechanism of the arms shifted to the front, shoulders lowered
- Shoulder blades protracted forward
- Cervical spine lengthened
