Background: Central sensitization (CS) is a state of heightened sensitivity of the central nervous system to both noxious and non-noxious stimuli. The Central Sensitization Inventory (CSI) is a sound screening tool to help clinicians to detect patients with CS. To date, no Gujarati version exists. Objectives: The aim of this study was to translate and cross-culturally adapt the CSI into Gujarati, and to check content validity, face validity, internal consistency, test-retest reliability, agreement and minimum detectable change (MDC) of CSI-G in chronic low back pain (CLBP) patients. Methods: Translation and cross-cultural adaptation of the original English version of the CSI-G was performed according to published guidelines. The content validity was ascertained by 23 healthcare professionals. The internal consistency, test-retest reliability, agreement and MDC was determined on CLBP patients (n=31) with a time interval of 7-days. Results: The content validity and Face validity was found to be excellent. The internal consistency was excellent (Cronbachs α=0.914) and MDC was found to be 5.092 points. The test-retest reliability showed very high correlation in CLBP patients (ICC = 0.971). Conclusion: The original CSI was translated into Gujarati and did not pose any problems during data acquisition. The CSI-G seems to be reliable instruments to measure CS in Gujarati patients with CLBP. [Bid D NJIRM 2016; 7(5):18-24]
