Abstract

AbstractIntroduction: The purpose of this study was to determine the inter tester and intra tester reliability of 5 static and 3 dynamic palpation tests, and three pain provocation tests used to diagnose sacroiliac joint dysfunction.Method: Five static palpation tests, namely palpation and assessment of the levels of the 1) posterior superior iliac spine (PSIS) in standing position, 2) PSIS in sitting position, 3) anterior superior iliac spine (ASIS) in standing position, 4) Medial Maleolus (MM) in supine position, and 5) MM in long sitting position, and three dynamic (motion palpation) tests, 1) the Gillet test, 2) the standing flexion test, and 3) the sitting flexion test were performed on ten asymptomatic subjects by four examiners. Each test was performed four times by each examiner resulting in 1280 assessments in total. Pain provocation tests were posterior pelvic pain provocation test (PPPPT) or posterior shear test, patric test, and hip resisted abduction test. The Study included twenty women with chronic low back pain, aged between 20 to 30 years. Each of pain provocation tests were performed two times by two examiners.Results: Reliability was determined using Kappa Statistic which allows assessment of observer agreement for more than two examiners and multiple examiners. Intra examiner agreement of static palpation tests revealed a range of reliability from slight to good. Kappa coefficient yielded intra examiner agreement that ranged between slight to good for the PSIS in standing position (0.18-0.75), slight to moderate for the ASIS (0.15-0.5), and slight to fair (0.1-0.35) for other static and all motion palpation tests. Inter examiner reliability of all the static and dynamic tests did not exceed slight reliability (0.0-0.2). Kappa value for intertester reliability of posterior shear test, patric test, and hip resisted abduction test for right limb was 0.7, 0.7, and 0.6, and for left one was 0.7, 0.78, 0.34, respectively, and the mean value of kappa for intratester reliability was between 0.75 and 0.91.Conclusions: The results of this study suggest that the reliability of palpation and assessment of the levels of the PSIS, ASIS, and MM in static positions, and the gillet, standing flexion, and sitting flexion tests as indicators of sacroiliac joint dysfunction still remain questionable. Therapists should reconsider the usefulness of evaluation techniques that rely on the assessment of the anatomical symmetry of bony landmarks of the innominates in static and dynamic conditions. About pain provocation tests, the results showed that posterior shear and hip resisted abduction tests are reliable tests to diagnose the pathology in the sacroiliac joints. The reliability of patric test that commonly used to determine the sacroiliac joints pathologies is in under question.Keywords: Sacroiliac joint, Reliability, Static tests, Dynamic tests, pain provocation tests
