The aim of this study was to evaluate a new modified visual analog scale, called the dolorimeter, together with a verbal rating scale (VRS) and a linear visual scale (VAS), in the measurement of acute postoperative pain. The scales were evaluated with reference to their sensitivity, reliability and validity, and correlation. During the study 200 patients 11-70 years of age (125 men, 75 women) were interviewed after orthopedic surgery to ascertain the intensity of the pain. ⋯ On the other hand, the high sensitivity of the two analog scales which patients can use to determine their individual pain intensity proved to be much more sensitive. All three methods correlated statistically; the highest correlation coefficients were found between the analog scales VAS and the dolorimeter. Because the dolorimeter is clearly preferred to the other methods, especially by elderly patients, we came to the conclusion that the dolorimeter is less abstract than the VAS and more practical to handle.
