Are any of you clinicians who might be wondering what historical feedback can help cue you into a patient with SI pain? The good news is you only have to ask one question (that has any real relevance statistically).
Michaelsen, Pauza, McLarty, and Bogduk showed that most historical data are not useful for diagnosing SI joint dysfunction with the exception of patients stating “relief with standing” which had a likelihood ratio of 3.9. This means that people who report reduced pain at the lower back with standing are 3.9 times more likely to have a SI joint dysfunction. The Confidence Interval (CI) was not reported.
So if you are thinking of altering your back evaluation forms to help screen for SI dysfunction, make sure this question is included.
