Widespread Pain Index

The Fibromyalgia Widespread Pain Index or WPI is a patient assessment that assesses how much of the body regularly causes pain. It was introduced by the American College of Rheumatology in the 2010 diagnostic criteria for fibromyalgia.

WPI and Tender points
The Widespread Pain Index replaces the older tender point scoring and does not rely on a trained clinician pressing on painful areas.

WPI scoring
The WPI score is between 0 and 19.
