Which postural landmarks are used to assess the pelvis from a posterior view?

To assess the pelvis from a posterior view, the correct landmarks to focus on are the Posterior Superior Iliac Spines (PSIS) and the gluteal fold. The PSIS are bony protrusions located at the back of the pelvis, which provide a reliable indicator of pelvic alignment. Observing the position and levelness of the PSIS in relation to the gluteal fold allows for an assessment of pelvic tilt and overall postural alignment.

The gluteal fold represents the boundary where the buttocks meet the thighs, serving as a practical reference point to evaluate symmetry and potential imbalances in the pelvis. By measuring these landmarks in a posterior view, practitioners can determine whether the pelvis is in a neutral position or if there is an anterior or posterior tilt.

Other options present landmarks that are less relevant for assessing the pelvis specifically from a posterior perspective. The levelness of the ears primarily relates to head and neck alignment rather than pelvic positioning. Similarly, the patella and popliteal fossa are associated with the knee and lower leg, which do not directly contribute to evaluating pelvic alignment. Therefore, the combination of the PSIS and gluteal fold is most appropriate and relevant for accurate assessment of pelvic posture from the posterior
