What is it used for?

  • Assessing Upper Cervical Instability (specifically the Alar Ligament which stabilizes C2).

How to Perform

  • Position: Patient supine.
  • Action: Grip the C2 spinous process (back of the upper neck) with a pincer grip.
  • Movement: Side-bend or rotate the patient's head slightly.

Interpretation of Results

  • Normal: The C2 spinous process should move immediately in the opposite direction of the side-bend.
  • Positive (Instability): A lag or delay in C2 movement suggests ligament laxity.
