What does the term 'centralization of pain' imply?

The term 'centralization of pain' refers to the phenomenon whereby pain that is typically located in the limbs or peripheral areas begins to reduce in intensity and is perceived more centrally, often in the spinal region. This can signify a shift in the source or perception of pain as it becomes more focused and localized, moving toward the spine rather than being experienced in the more distant regions of the body.

In the context of rehabilitation and physical therapy, centralization can be a positive sign indicating that the treatment strategy is effective and that the underlying issue may be resolving. Professionals often monitor how pain progresses in response to therapeutic interventions, where an improvement manifested as centralization suggests a favorable direction in the recovery process.
