Objectives: Key diagnostic decisions often turn on measurement of change in pain intensity after diagnostic anesthetic blocks. This study aimed to introduce a new direct measure pain intensity change and compare it with percent change as calculated from the traditional preprocedure and postprocedure pain visual analog scales. Methods: Shoulder pain patients enrolled in a diagnostic accuracy study comparing clinical variables with image-guided local anesthetic injections were assessed with both the traditional preprocedure and postprocedure visual analog scales and the new direct method. Percent change in pain intensity was calculated with both instruments and were compared using statistical methods. The percentage …
