What is the correct LOD when palpating thoracic vertebral rotation?

The correct line of drive (LOD) when palpating for thoracic vertebral rotation is from posterior to anterior (P-A) and inferior to superior (I-S). This technique allows the practitioner to assess the rotation of the thoracic vertebrae effectively.

When palpating the thoracic spine, using a P-A approach provides direct access to the vertebral bodies and allows the practitioner to feel the subtle movements and rotations that occur at each segment. The addition of the I-S component helps to distinguish rotational movement by stabilizing the vertebrae in the vertical axis while assessing their rotational aspect. This combined LOD effectively engages both the structural and functional elements of the vertebrae during palpation.

Thoracic spine rotation involves a complex interaction of vertebral bodies, facet joints, and surrounding soft tissues, making it critical to use a comprehensive approach to capture these nuances during examination. Thus, understanding and applying the appropriate LOD when palpating in this region enhances diagnostic skill and contributes to better clinical outcomes.
