What is it?
This tool was published in 2012 with the purpose of providing a single self-report instrument that identified symptoms associated with central sensitization and the quantified the degree of those symptoms.
There are two parts to the measure. Part A consists of 25 statements relating to current health symptoms. Each item is measured using a 5 point like scale with Never (0), Rarely (1), Sometimes (2), Often (3), and Always (4). This results in a cumulative score of 100. The higher the score the higher the likelihood of central sensitization. In a study by Neblett et al, they identified a clinically significant level of 40 as providing both good sensitivity and specificity for the presence of central sensitization syndrome.
Having the patient complete the CSI could prove to be a useful tool for not only the clinician, but also for the patient. Understanding the source of the muscolskeletal pain can be an important education tool.
