Take a full head-to-toe image of the person.
Anterior posture screening, from the front image:
- Lateral Head: The angle of the head off a plumb line through the person’s center point
- Acromions Horizontal Alignment: The difference of a line through the acromions (shoulder points) compared to a calculated horizontal level line through the person’s center point.
- Acromions-Sternum Angle: Angle between the jugular notch and the xiphoid appendix (sternum) and a line between the two acromions (shoulders).
- ASIS Horizontal Alignment: The angle between the two anterior superior iliac spine points (ASIS/pelvis line) compared to a calculated horizontal level line through the person’s center point.
- ASIS Leg Angle: An angle of a line through the trochanter (top of leg) and patella (knee) compared to the anterior superior iliac spine (ASIS/pelvis) line.
- Knee Lateral Angle: The angle between the upper leg (trochanter to petella) and the lower leg (tibial tuberosity to the lateral malleolus).
Lateral posture screening, from the side image:
- Forward Head: The angle of the head compared to the body torso (shoulder to hip).
- Forward Shoulder: The angle of the torso compared to the upper leg (trochanter to lateral femoral condyle).
- Forward Hip: The angle of the upper leg compared to the lower leg (lateral femoral condyle to ankle).
- Forward Knee: The angle of the lower leg off a calculated plumb line through the person’s center point.
- Pelvis-Leg Angle: The angle between the line of the anterior and posterior superior iliac spine points (ASIS to PSIS) compared to the lower leg (lateral femoral condyle to ankle).
- Knee Extension Angle: The angle of the upper leg compared to the lower leg (lateral femoral condyle to lateral malleolus).
