Which statement identifies the CP for thoracic extension as being the pad of the 3rd digit?

• A. Pad of 3rd digit (#5)
• B. Pad of 2nd digit (#6)
• C. Pad of 4th digit
• D. Pad of the thumb

Answer: (A)

In this palpation approach, choosing the right contact point is what lets you feel the vertebral segmental motion clearly during thoracic extension. The pad of the middle finger provides a broad, stable, and sensitive contact that sits well along the spinous processes, allowing you to sense subtle movements and end-feel as the patient extends. It offers a good balance of surface area and control, so you can detect exactly how each thoracic segment responds. The thumb pad tends to be bulkier and may shift contact or obscure fine sensations; the pads of the index or ring fingers have a smaller contact area and can be harder to maintain consistent pressure along the curved midline; the pinky-side contact is less practical for midline thoracic palpation. For reliable assessment of thoracic extension, the pad of the middle finger is the best choice.
