WPI · Widespread Pain Index

1 Before you use it

What it is

Count of body regions with pain in the last week, out of 19. Part of the fibromyalgia diagnostic criteria, used together with the Symptom Severity Scale.

When to reach for it

When widespread pain is part of the picture and you are building a case for medical review.

It also usefully documents distribution over time, which a single body chart doesn't.

Scoring

One point per painful region, 0–19. Use the defined region map, not a free-form body chart.

What it doesn’t measure

Diagnose fibromyalgia, and it says nothing about severity or impact.

3 Reading the score

Interpreting it

Interpreted only in combination with the Symptom Severity Scale, as part of a diagnostic criteria set applied by a medical practitioner. No verified thresholds are carried in our library and none are printed here.

A physiotherapist's role is recognition and referral, not diagnosis.

Is the change real?

No verified MCID or MDC is carried in our library for this measure, so the number on its own cannot tell you a change is real. Compare it to this patient's own baseline and say what changed functionally.

Student trap. Counting regions off your own body chart. The 19 regions are defined — use the map.
