What is the correct line of drive (LOD) while palpating an anterior glide on the ilium?

The correct line of drive (LOD) for palpating an anterior glide on the ilium is achieved by using a posterior-anterior (P-A), medial-lateral (M-L), and inferior-superior (I-S) motion. This combination of directions aligns with the anatomical orientation and function of the ilium in relation to the sacrum.

When palpating for an anterior glide, it is essential to apply pressure in a manner that facilitates movement of the ilium toward the anterior plane. The P-A aspect refers to applying pressure from the back of the ilium towards the front. The M-L component allows for movement toward the midline of the body, assisting in the alignment and assessment of the ilial position. Lastly, the I-S direction stabilizes the lower portion while allowing for effective movement.

This combination is vital for accurately assessing the mobility of the ilium and understanding how it interacts with the sacrum within the pelvic girdle, especially during motions that involve the lower limbs and core stability functions.
