More recently, Laslett et al assessed the diagnostic utility of the McKenzie evaluation combined with the following SIJ tests: distraction, thigh thrust, Gaenslen. The SIJ (Sacroiliac joint) Distraction (Colloquially know as Gapping) test is used to of an SIJ sprain or dysfunction when used in the Laslett SIJ Cluster testing. (Laslett et al., ). Conceptually, it seems reasonable to propose that stress testing of the SIJ should provoke pain of SIJ origin. However, clinical stress tests .

This test stresses the anterior sacroiliac ligaments. The patient lies supine and the examiner applies a vertically orientated, posteriorly directed force to both the anterior superior iliac spines ASIS [1] [3] [4] [5]. However, Laslett does not suggest any timings or changes in force. Because of the lack of standardization in the technique it is quite feasible different therapists will practise this test different ways, giving rise to variability in response and lowering the inter-tester reliability.


Evidence-Based Diagnosis and Treatment of the Painful Sacroiliac Joint

A test is positive if it reproduces the patient’s symptoms. This indicates SIJ dysfunction or a siij of the anterior sacroiliac laslet [1] [2] [3] [4] [5]. However, this test should be used in concordance within a SIJ testing cluster to ensure maximum reliability and validity when confirming hypotheses [7] [8] [3] [5] [9] [10] See Laslett SIJ testing cluster for further information. Patient Spectrum Consecutive admissions of AS patients with varying stages of progression.

Negative Likelihood Ratio LR- — The ratio of a negative test result in people with the pathology to a negative test result in people without the pathology. Reliability — Likelihood of results from test to be reproduced again Expressed as percentage or as decimal.

Test has reasonable specificity and inter-rater reliability and should be used as an assessment tool in pregnant women. Unclear if intermediate results reported. Excluded if midline pain above L5 Reference Standard Every subject received reference standard diagnosis via Fluroscopy contrast guidance of a diagnostic laelett injection. Independent blind comparisons with Gold standard Therapist and Radiologist blinded to opposite assessment.


Gold standard diagnostic spinal injection used. Test characteristics Presented as expected Reproducibility Concisely and clearly detailed method and results analysis.

Study tests inter-rater reliability of multiple tests but still unclear Independent blind comparisons with Gold standard Unclear from abstract Test characteristics Unclear from abstract Reproducibility Some description of methods and analysis in abstract but not reproducible. Test characteristics Presented as expected Reproducibility Very detailed method and analysis.

Sacroiliac Distraction Test

Test has acceptable reliability when used in early stage sacroilitis. However, reliability, sensitivity and specificity improved when in a multi-test cluster. Accepted pts who would normally be tested for SIJ dysfunction.

Reference Standard Reference standard identical to index test but carried out on every subject by independent and blind assessor Independent blind comparisons with Gold standard No gold standard used but assessors independent and blind of each other.

Test characteristics Only reliability and assessor agreement assessed Reproducibility Very detailed and specific description of method and analyses.

Reference Standard Tests performed on every subject twice but 2 random, separate, independent and blind assessors in a random order.

Independent blind comparions with Gold standard Reference sii same as index test and not gold standard. Assessors were independent and blinded. Test characteristics Only reliability and assessor agreement reported.

Reproducibility Well detailed methodology and analyses. Reliability of the test is moderate to good. However, test is better when performed in a multi-test cluster.
