1 Before you use it
What it is
Twenty-five items in Part A covering symptoms associated with central sensitisation — fatigue, unrefreshing sleep, widespread pain, concentration, sensitivity to light and noise, and more. Part B asks about previously diagnosed conditions.
When to reach for it
Persistent, widespread or disproportionate presentations where the symptom picture doesn't fit the tissue.
2 Giving it
Scoring
Part A: 25 items, 0–4 each, totalling 0–100. Higher means more symptoms. Part B is a checklist, not scored.
What it doesn’t measure
Confirm a pain mechanism, or diagnose anything. It flags a symptom cluster worth exploring.
3 Reading the score
Interpreting it
**A cut-point around 40 is commonly cited.
Be careful with the language. The instrument measures a symptom cluster; it does not confirm a mechanism, and telling a patient they have "central sensitisation" on the basis of a questionnaire score is a bigger claim than the score supports.
Is the change real?
Student trap. Turning a score into a diagnosis in front of the patient. It's a symptom questionnaire, not a mechanism test.

This is a learning tool. It does not diagnose patients and does not replace your clinical educator.
