What should be compared when palpating the ribcage during a front view assessment?

When palpating the ribcage during a front view assessment, the most relevant comparison is between the ribcage and the ASIS (anterior superior iliac spine). This comparison is key because it helps to assess the alignment and symmetry of the upper body in relation to the pelvis. The ASIS serves as a stable landmark that can provide valuable insight into postural deviations or alignment issues.

By evaluating the ribcage against the ASIS, you can determine if there are any discrepancies that might indicate issues such as rotation or lateral shifts. This relationship is important for understanding how the upper body and lower body mechanics work together and how they may affect movement and overall posture.

Other comparisons, while they may be relevant in different contexts, do not provide the same level of insight for a front view assessment. For example, comparing the ribcage to the sternum focuses on the thoracic region but does not take into account the pelvic alignment. Similarly, assessing the top of the iliac crest in relation to rib angle looks at horizontal alignment rather than the critical vertical relationship between the ribcage and pelvis.
