Central Sensitization Inventory (CSI) Flow

Central Sensitization Inventory flow


The CSI,developed in 2012 [1], is a two-part questionnaire that contains a survey (Part A) that assesses the frequency of health-related symptoms associated with central sensitivity syndromes (CSS) and a brief survey (Part B) asking if patients have been diagnosed with specific disorders, including seven separate CSSs [2].

The Central Sensitization Inventory flow contains the Central Sensitization Inventory (CSI) questionnaire and associated calculation. After form submission, the Central Sensitization Inventory calculation is executed automatically. It's easy to extend this flow with conditional logic based on the interpretation of the Central Sensitization Inventory calculation.

Questions and Scoring

The questionnaire can be found here.

Only Part A of the CSI is used for scoring. Participants are asked to rate each question on a 5-point scale with 0 meaning “never” and 4 meaning “always.”

Part B is not scored.


The highest possible total score is 100.

Higher CSI scores represent greater self-reported symptomology. A cutoff score of 40 or greater has shown acceptable psychometrics for identifying patients with central sensitivity syndromes [2] and has been recommended in guidelines for pain mechanism classification. [3]
