Alar Ligament Stress Test (with Rotation & Sidebending) | Demonstration & Interpretation

The video tutorial covers the evaluation of pathologies in the upper cervical spine, focusing on the alar ligament stress test. It explains the procedure for performing the test, including the stabilization of the C2 spinous process and the movements involved. The video also discusses how to interpret the test results, distinguishing between positive and negative outcomes. Additionally, it highlights the psychometric properties of the test, such as sensitivity and specificity, and the benefits of performing multiple movements to improve diagnostic accuracy.
