How the Scales are Structured

example score

72/100

Central Sensitization Scale (CSS)

Measures the severity of self-reported symptoms associated with central sensitization (heightened nervous system reactivity).

Low–Moderate

High

Very High

0 – 49: Low–Moderate | 50 – 59: High | 60 – 100: Very High

A score of 72 falls in the Very High range, indicating a pronounced level of symptoms commonly associated with central sensitization.

DATA-BASED USER COHORTS

Who Usually Takes This Test?

People with chronic widespread pain

41%OF USERS

Those with long-lasting, body-wide pain (often with fatigue and sleep issues) use it to see whether an overactive nervous system may be amplifying symptoms.

Migraine and headache sufferers

34%OF USERS

People with frequent migraines or persistent headaches take it to check if heightened sensitivity to light, sound, or touch may be driving their pain pattern.

Unexplained sensitivity after injury

25%OF USERS

Those whose pain feels out of proportion or lingers after an injury or surgery use it to understand possible pain sensitization and guide next steps in care.

WHAT THE TEST MEASURES

About This Assessment

Central Sensitization Inventory (CSI-R) Test - Symptoms and Signs

somatics

This self-report measure is used to screen for symptoms commonly associated with central sensitization and related patterns of heightened central nervous system responsivity. The Central Sensitization Inventory (CSI-R) was developed to support efficient clinical characterization of symptom burden in patients presenting with chronic or complex pain complaints.

The instrument contains 25 items and typically takes about 5 minutes to complete. Items assess the frequency or severity of somatic and sensory symptoms that may be consistent with central sensitization; results are intended to inform clinical formulation and guide follow-up assessment rather than serve as a standalone diagnosis. The Central Sensitization Inventory (CSI-R) is commonly referenced in the pain and behavioral health literature (Sullivan & Turk) and can be integrated with history, examination findings, and other validated measures.
