New outcome measure

An IRB approved a study aiming to assess whether weekly back massages could relieve the pain of patients recovering from spinal surgery. A group that received the back massages would be compared with a group that did not. The initial protocol stated that the primary outcome measure would be self-reported pain levels. As the study was about to begin, however, a researcher read a newly-published article that indicated back massages may also have an effect on patients’ ability to carry out everyday tasks. The researcher therefore added a set of questions to participants concerning how well they can manage such tasks.
