Multicenter Study
Assessing validity of the original and Rasch versions of the central sensitization inventory with psychophysical tests in people with knee osteoarthritis.
To determine the extent of agreement between the original Central Sensitization Inventory (CSI) and the Rasch-calibrated version (RC-CSI) and to explore the association of both versions with psychophysical tests and their respective sensitivity and specificity. ⋯ Because of poor variance explained with psychophysical tests and high false positive rates, our results indicate that there is little clinical value of using either version of the CSI in people with knee osteoarthritis.
