The LOD for a single hand adjustment is at which location?

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

Answer: (A)

Line of Drive is the path the thrust should travel in a one‑hand adjustment, and you want that line to align with the limb’s axis for a precise, controlled delivery. The elbow makes the best contact point because it sits at a stable pivot that lets your forearm act as a solid lever, guiding the thrust straight along the limb toward the target joint. This setup gives you better leverage, control, and accuracy while minimizing unwanted torque on your body. The other landmarks don’t provide the same leverage or alignment. The episternal notch is just a chest landmark and isn’t aligned with a limb joint. The wrist is too distal and would reduce control and stability, and the shoulder would misalign the line of drive, making the thrust harder to direct precisely.
