The study objective was to assess the concurrent validity of the Electronic Descriptive Pain Scale (EDPS), a pain scale built into a transcutaneous electrical nerve stimulation device. One hundred patients in an outpatient physiotherapy (PT) clinic participated (mean age 41.30 years, SD 13.95). Before and after a PT treatment, subjects rated their current pain intensity with the EDPS, a visual analogue scale, a numerical pain rating scale, and the McGill Pain Questionnaire's Present Pain Intensity. The results showed relatively high significant correlations between the EDPS and each of the other pain scales.
