What must be compared when evaluating the pelvis alignment from the front view?

When evaluating pelvis alignment from the front view, comparing the anterior superior iliac spine (ASIS) palpation and iliac crest height is essential. The ASIS is a bony prominence on the front of the pelvis that helps practitioners assess pelvic tilt and alignment. By palpating both the ASIS and the iliac crest, which are the top edges of the pelvic bones, it becomes possible to identify any asymmetries or discrepancies between the sides of the pelvis. This evaluation is crucial because differences in height at the iliac crests or malpositioned ASIS can indicate issues such as pelvic obliquity or rotation, which may affect overall posture and biomechanics.

The focus on knee alignment and shoulder height is less relevant for assessing pelvic alignment, as these areas provide information about lower and upper body positioning instead. Similarly, foot posture and spinal curvature address different aspects of the body’s alignment, not specifically the position and alignment of the pelvis from the front perspective. Thus, the comparison of ASIS palpation and iliac crest height specifically targets the required assessment for evaluating pelvic alignment effectively.
