What does Sphinx test tell you?

Purpose of Test: To assess for sacral torsion. Assess sacral sulci and inferior angles to see if they are symmetrical or asymmetrical. Have the patient move up onto his/her elbows, so he/she is prone on elbows. If the landmarks become more symmetrical, it is a forward torsion.

What is a positive seated flexion test?

Test Position: Sitting. Performing the Test: The examiner has a hand on each PSIS. The patient bends forward, while the examiner is comparing the movement of each PSIS. A positive test is if greater superior motion is felt on one PSIS compared to the other.

What is the Fortin finger test?

In the Fortin finger test, the patient points to the area of pain with one finger. The result is positive if the site of pain is within 1 cm of the PSIS, generally inferomedially. The Patrick test or Faber maneuver involves flexion, abduction, and external rotation of the hip.

When does the sacrum become a forward torsion?

If the landmarks become more symmetrical, it is a forward torsion. If the landmarks become more asymmetrical, it is a backward torsion. Diagnostic Accuracy: Unknown. Importance of Test: The sacrum has two commonly known positions: flexion (nutation) and extension (counternutation).

Is there a positive test for sacral thrust?

One single positive test does not have high diagnostic accuracy but a combination with other sacroiliac pain provocation tests gives valid evidence for sacroiliac dysfunction. The test is also known as: Sacral compression test. Downwards pressure test. Sacral spring test.

What is the purpose of the torsion test?

In this torsion testing experiment, the torsion test was evaluated as a system for calculating the torsional rigidity (GJ), modulus of rigidity (G), and the shear yield stress (τ) for aluminum, mild steel, and brass.

What is the technique of the sacral spring test?

Sacral spring test; Technique. With the patient prone, the examiner applies an anteriorly directed pressure over the sacrum. One hand is placed directly on the sacrum and is being reinforced by the other hand. The purpose is to apply an anterior shear force to both sacroiliac joints since the ilia are fixed by the examination bench.
