Specific Torsion Test for Lumbar Instability | Rationale & Interpretation

The video tutorial explains the torsion test, a method to assess rotational lumbar instability. It details the procedure, including patient positioning and stabilization techniques, and explains the mechanics of lumbar rotation. The video also covers how to determine the direction of rotation and interpret test results, emphasizing the importance of comparing results across vertebral segments to identify excessive rotation and potential instability.
