Prone Torsion Test for Lumbar Instability | Rationale & Interpretation

The video tutorial explains the prone torsion test, an alternative method for assessing rotational lumbar instability. It covers the procedure, including hand positioning and force application on vertebrae L4 and L5, and explains the concept of contralateral rotation. The video also compares the prone torsion test with the specific torsion test, highlighting differences in body rotation and expected outcomes.

What is the purpose of the prone torsion test?

Describe the positioning of the patient during the prone torsion test.

Explain the role of the caudal and cranial hands during the test.

How does moving the spinous process to the left relate to spinal rotation?

What is the significance of assessing contralateral rotation during the test?

Compare the prone torsion test with the specific torsion test in terms of patient positioning.

What indicates a positive test result in the prone torsion test?
