The LOD for a double hand adjustment is at the episternal notch.

The LOD for a double hand adjustment is at the episternal notch.

• A. Shoulder
• B. Elbow
• C. Episternal notch
• D. Thorax

Answer: (C)

The line of drive is defined by a precise, palpable landmark that guides the thrust. For a double-handed adjustment, using the episternal notch as the LOD provides a stable, midline reference at the top of the sternum. Directing the thrust toward this notch helps align the vector with the spine, targeting the upper thoracic region and keeping the force directed along the body's axis rather than outward toward the shoulder or across the chest. The shoulder and elbow describe how you contact or leverage, but they don't specify the directional target, and the thorax is too broad a term to define a specific line of drive. So the episternal notch serves as the correct LOD for this technique.
