A new pain rating scale, Analogue Chromatic Continuous Scale (ACCS), has been developed. The ACCS was tested in fifty consecutive patients suffering from pain of different origins, and compared with a simple descriptive scale (SDS) and a traditional 100 mm visual analogue scale (VAS). ⋯ The ACCS proved to be more sensitive than VAS (P less than 0.05), allowing a greater discrimination of grades of pain. Furthermore, the ACCS is very easy to use.
