Which statement correctly identifies the CP for thoracic extension?

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

Answer: (C)

The strongest contact point for sensing thoracic extension is the pad of the middle finger on the lower (inferior) hand. This surface gives a precise, stable, and sensitive contact to feel the spinous processes as the thoracic spine extends. The middle finger pad is large enough to maintain good contact and small enough to detect subtle changes in bony alignment and tissue depth, while being comfortable to hold steady through the movement. Using the thumb or other digits tends to place pressure differently or reduce tactile discrimination, making it harder to accurately follow the spine. So, the middle finger pad on the lower hand is the best CP for assessing thoracic extension.
