Pain measurement
In medicine, pain measurement is the use of "scales, questionnaires, tests, and other methods used to assess pain severity and duration in patients or experimental animals to aid in diagnosis, therapy, and physiological studies."[1]
Numeric rating scale
Pain may be quantified on a pain numeric rating scale (NRS) that ranges from 0-10 points (0 means no pain); however, the accuracy of such as scale (using a cut point of 4 or more) for predicting pain that interferes with functioning is:[2]
- sensitivity 64%
- specificity 83%
This score does not correlate with heart rate.[3]
Visual analog scale
Visual analog scales (VAS) have been used to measure pain. An observational study concluded "the minimum clinically significant change in patient pain severity measured with a 100-mm visual analog scale was 13 mm."[4]
Other scales
The PEG is a 3 item scale that rates pain and its impact on the patient's life.[5]
The McGill Pain Questionnaire is available.[6]
