The Central Sensitization Inventory (CSI) aims to evaluate symptoms thought to be associated with nociplastic pain. The CSI consists 25 items exploring emotional and somatic disorders associated with CS. Each response is scored from 0 to 4, yielding a total score of 0 to 100. A score of 40 or higher on the CSI means the presence of nociplastic pain.

The 8 subscales are scored from 0 to 100, with higher scores indicating better health status.

Quantitative sensory testing (QST) is a psychophysical method used to quantify somatosensory function in patients. In QST will be used various stimuli static thermal (thermotest), static mechanical ( a painter brush), pinprick (a calibrated pin) and vibration ( a tuning folk). QST will interrogate whether each stimulus is considered a sensory loss (negative sign) or sensory gain (positive sign or hyperalgesia).
