Which postural landmarks are used to assess the pelvis from the back?

The correct answer focuses on the PSIS (Posterior Superior Iliac Spine) and the gluteal fold as key postural landmarks for assessing the pelvis from a posterior view.

The PSIS is a bony prominence on the posterior aspect of the pelvis, easily palpated and used by practitioners to determine pelvic alignment. Its position can indicate whether the pelvis is tilted, rotated, or misaligned. The gluteal fold, which is the junction where the buttocks meet the thigh, serves as an important reference point for assessing the overall position of the pelvis in relation to the legs. By measuring the distance and alignment between the PSIS and the gluteal fold, practitioners can evaluate various postural aspects of the pelvis, such as whether it is level or if there are any asymmetries that could suggest muscular imbalances or postural issues.

This approach is essential for understanding how the pelvis interacts with the rest of the body during movement, particularly in modalities like Pilates, where pelvis positioning plays a critical role in performance and injury prevention.
