▶️ Sacroiliac test is a term that refers to a group of special tests that are used to assess the function and pain of the sacroiliac joint (SIJ), which is the joint between the sacrum and the ilium bones of the pelvis.
– The SIJ is responsible for transmitting the load from the upper body to the lower limbs, and for allowing some movement between the pelvis and the spine. The SIJ can be affected by various conditions, such as inflammation, infection, trauma, arthritis, pregnancy, or biomechanical dysfunction, that can cause pain in the lower back, buttock, groin, or leg.
– There are many types of sacroiliac tests, but they can be broadly classified into two categories: pain provocation tests and mobility tests.
Pain provocation tests are designed to elicit or reproduce the patient's pain by applying pressure or stress to the SIJ structures, such as the ligaments, capsules, or nerves.
Mobility tests are designed to assess the movement or asymmetry of the SIJ by palpating or measuring the position or motion of the bony landmarks of the pelvis, such as the iliac crests, the posterior superior iliac spines (PSIS), or the anterior superior iliac spines (ASIS).
– Some examples of pain provocation tests are: distraction test, thigh thrust test, Gaenslen's test, compression test, and sacral thrust test. These tests involve applying a force to one or both sides of the pelvis or the thigh in different directions and positions to provoke pain in the SIJ region. A positive result is indicated by pain or replication of the patient's symptoms on the same side (ipsilateral) or opposite side (contralateral) of the applied force. A negative result is indicated by no pain or pain other than the patient's symptoms.
– Some examples of mobility tests are: standing flexion test, sitting PSIS palpation test, supine long sitting test, prone knee flexion test, and stork test (also known as Gillet test).
These tests involve asking the patient to perform a movement or posture that involves flexion, extension, or rotation of the hip or spine while palpating or observing the movement of the PSIS or ASIS on one or both sides of the pelvis. A positive result is indicated by reduced or absent movement of the PSIS or ASIS on one side compared to the other side. A negative result is indicated by symmetrical and normal movement of both PSIS and ASIS.
• The flamingo test:- is another type of mobility test that involves asking the patient to stand on one leg while pulling the hip of the opposite side into 90 degrees or more of flexion. The examiner then palpates both PSIS with their thumbs and compares their movement. A positive result is indicated by reduced or absent movement of the PSIS on the same side (ipsilateral) as the flexed hip. A negative result is indicated by symmetrical and normal movement of both PSIS.
– The accuracy and reliability of sacroiliac tests are controversial and variable in different studies. Some studies suggest that no single test can reliably diagnose SIJ dysfunction or pain, and that a combination or cluster of tests may increase the diagnostic utility and validity.
Other studies suggest that some tests have higher sensitivity and specificity than others, and that some tests may be influenced by other factors such as lumbar spine pathology, hip pathology, muscle strength, or psychological factors. Therefore, sacroiliac tests should be used with caution and within a comprehensive clinical reasoning process that considers other aspects of history taking, physical examination, differential diagnosis, and response to treatment.

Critical Evaluation:
The article provides a detailed overview of sacroiliac tests, outlining their purpose and categorizing them into pain provocation and mobility tests. The arguments presented are coherent and logically structured, making it easy for readers to follow the discussion. However, the article could strengthen its claims by incorporating specific studies or statistics that highlight the effectiveness or limitations of these tests. While it acknowledges the controversy surrounding the accuracy and reliability of sacroiliac tests, it would benefit from a more balanced exploration of both sides of the argument, including potential biases in the studies referenced. In real-world applications, understanding the limitations of these tests is crucial for healthcare professionals, as it impacts diagnosis and treatment plans for patients with lower back pain.
Quality of Information:
The language used in the article is generally clear and accessible, making it suitable for a broad audience. Technical terms, such as "sacroiliac joint" and "asymmetry," are introduced without extensive explanation, which may leave some readers confused. Providing brief definitions or context for these terms would enhance understanding. The information appears accurate and reliable, with no evident signs of fake news or misleading content. However, the article does not cite specific studies or sources, which raises questions about the reliability of the claims made. It does not seem to introduce new ideas but rather summarizes existing knowledge about sacroiliac tests. The article could add value by presenting unique insights or findings that contribute to the field of study.
Use of Evidence and References:
The article lacks citations or references to support its claims, which diminishes the credibility of the information presented. While it mentions that some studies suggest variability in the accuracy of sacroiliac tests, it does not specify which studies or provide details about their findings. This absence of evidence creates gaps in the argument and leaves readers without a clear understanding of the basis for the claims made. More robust referencing would enhance the article's authority and provide readers with resources for further exploration.
Further Research and References:
Further research could focus on the following areas:
- Comparative studies on the effectiveness of different sacroiliac tests.
- The impact of psychological factors on the perception of pain related to sacroiliac dysfunction.
- Longitudinal studies examining the outcomes of patients diagnosed with SIJ dysfunction using various testing methods.
- Exploration of alternative diagnostic tools or imaging techniques that may complement sacroiliac tests.
