Which statement about centralization is true?

Which statement about centralization is true?

• A. It refers to pain moving distally
• B. It refers to pain moving unpredictably
• C. It refers to any improvement in symptoms
• D. It refers to pain moving toward the spine with repeated movements

Answer: (D)

Centralization describes the process where pain that initially radiates away from the spine moves toward the spine (toward the center) with repeated movements or specific positions. This directional shift toward the spine is a positive sign that the mechanical issue driving the symptoms is responding to the loading or centralizing maneuvers. The statement that best captures this is pain moving toward the spine with repeated movements. Moving the pain distally would be peripheralization, not centralization. Pain that moves unpredictably isn’t the defining feature, and an overall improvement in symptoms doesn’t specify the direction of movement toward the spine, which is what centralization is about.
