Is your “Stiff Neck” actually a “Stuck” Collarbone? 🦴
If you feel a “pinch” or a hard stop when turning your head, the problem might not be your neck at all—it might be your sternoclavicular (SC) joint.
The Science of “Congruent” Rotation
In a healthy system, the body moves in a coordinated, “congruent” pattern. When you rotate your head to the left, your left clavicle (collarbone) doesn’t just sit there—it actually needs to rotate posteriorly (roll backward) and move slightly to allow the surrounding musculature and fascia to glide properly.
When the clavicle is “stuck” or fails to rotate, it creates a mechanical block at the base of the neck. This often results in:
Limited range of motion.
A feeling of “tightness” that stretching doesn’t fix.
Compensatory strain on the cervical vertebrae.
This exercise uses a manual tactile cue to retrain that relationship:
Lateral Pull: Use your hand to gently guide the clavicle away from the midline (manubrium).
Posterior Rotation: Promote a backward roll of the bone.
Active Rotation: Maintain that position while slowly rotating your head to the same side.
You aren’t just stretching; you are retraining your brain and joints to move as a single, efficient unit.
