What was measured
* Subjective pain scores were captured using the Visual Analog Scale (VAS). Subjects were asked to "Please rate your current pain level with no movement (rest), with a cough, and with a swallow". Subjects marked a point on a 100-mm line anchored "no pain" on the left end and "worst possible pain" on the right end.
* Pain literature reports that scores in the 10-30mm range correlate clinically with mild pain, in the 30-60 or 70mm range with moderate pain, and in the \>70 range with severe pain
