Do you do these 4 SI Joint assessment tests?
- the standing flexion test,
- the prone knee flexion test,
- the supine long sitting test,
- and palpation of posterior superior iliac spine (PSIS) heights in a sitting position
You may want to rethink your assessment techniques.
The intertester reliability of assessments of the presence of SIJ region dysfunction using a composite of 4 diagnostic tests was poor and was not dependent on the method of classifying the nature of the test results. Reliability for the individual tests was slightly higher than for the composite scores, but we still consider it to be inadequate for clinical use. Given our results and the limited generalizability of the work of Cibulka et al, we recommend an alternative approach for identifying patients suspected of having SIJ region dysfunction. Tests designed to provoke a patient’s pain appear to have more support for use in identifying patients who may have SIJ region dysfunction than do tests presumed to measure SIJ alignment or movement.
