Inter-examiner reliability of diagnostic criteria
DOI 10.1186/ISRCTN43417727
ClinicalTrials.gov identifier
EudraCT number
Public title Inter-examiner reliability of diagnostic criteria
Scientific title Inter-examiner reliability of diagnostic criteria for diagnosing sacroiliac joint - discogenic and facet joint pain
Acronym N/A
Serial number at source NL36822.078.11
Study hypothesis Investigate the inter-examiner reliability of diagnostic tests in diagnosing sacroiliac joint - discogenic and facet joint pain. Our study aims to assess the reliability between examiners (pain specialists and orthopedic surgeons are involved) of the clinical tests used to select the patients in these studies.
Lay summary Background and study aims
Different types of low back pain (e.g. sacroiliac, discogenic and facet joint pain) have been identified. Treatment has become more effective due to the availability of specific treatments. Several diagnostic tests have been developed, but little is known about whether different doctors use the same diagnostic tests. This study aims to find out the inter-examiner reliability of the different clinical tests used to diagnose patients.

Who can participate?
Patients aged 18 or over with signs and symptoms of low back pain.

What does the study involve?
A physical examination of patients is done independently by two experienced pain specialists and one experienced surgeon. The list of tests prescribed by the three doctors are then compared and the tests are judged based on their presence in the list.

What are the possible benefits and risks of participating?
Improving diagnostic tests for identifying subtypes of low back pain increases the possibility for better treatment. We expect that this will improve overall success in treatment. No major risks are involved in this study.

Where is the study run from?
This study is run from Lievensberg Hospital, Bergen op Zoom, The Netherlands.

When is the study starting and how long is it expected to run for?
The study started in January 2013 and is expected to run for two years.

Who is funding the study?
This study is funded by the Centre for Pain Medicine, Erasmus University MC, Rotterdam, The Netherlands.

Who is the main contact?
C.W.J. van Tilburg, MD, FIPP
