What changes when Mulligan NAGs, SNAGs & Self-SNAGs meets the cervical? Start with the patient's movement, assess safely, and see what the re-test reveals.

Specific variations
How this technique is applied in the cervical
Each variation below is written so you can follow patient setup, contact, direction, dose and the re-test that decides whether the technique earned a place in the plan.
01
CervicalSelected cervical segment
Cervical SNAG for Rotation
One question matters more than the name of this variation: will the patient notice a useful change in Cervical rotation and the patient's look-over-shoulder task.? The careful re-test gets the final word.
The change we are looking for
Improve a painful/restricted cervical rotation when a sustained segmental glide makes rotation immediately easier.
Primary target
Selected cervical segment
The movement that tells us
Cervical rotation and the patient's look-over-shoulder task.
Patient focus
Improve a painful/restricted cervical rotation when a sustained segmental glide makes rotation immediately easier.
Therapist verifies
Cervical rotation and the patient's look-over-shoulder task.
Success signal
Keep the technique only if the re-test shows a meaningful improvement in cervical rotation and the patient's look-over-shoulder task. without symptom worsening.
Full clinical application
1
Position the patient
Sitting upright with the head in neutral and the painful rotation measured first.
2
Set the contact
Apply the trained facet-directed contact at the selected segment; the patient's head remains under their own active control.
3
Apply the technique
Maintain the segmental glide while the patient actively rotates into the previously limited direction. The movement should be pain-free or clearly improved.
4
Dose & re-test
6–10 repetitions; repeat 1–3 sets only if improvement is maintained. Re-test: Cervical rotation and the patient's look-over-shoulder task.
Clinical pearl
A SNAG is movement plus glide; if the patient is passive, it is not a SNAG.
Safety / avoid
Cervical screening and clinician training are required.
02
CervicalCervical self-management
Self-SNAG for Cervical Rotation
One question matters more than the name of this variation: will the patient notice a useful change in Pain-free rotation immediately after the self-SNAG.? The careful re-test gets the final word.
The change we are looking for
Allow the patient to reproduce a helpful pain-free glide independently when they can control the technique safely.
Primary target
Cervical self-management
The movement that tells us
Pain-free rotation immediately after the self-SNAG.
Patient focus
Allow the patient to reproduce a helpful pain-free glide independently when they can control the technique safely.
Therapist verifies
Pain-free rotation immediately after the self-SNAG.
Success signal
Keep the technique only if the re-test shows a meaningful improvement in pain-free rotation immediately after the self-snag. without symptom worsening.
Full clinical application
1
Position the patient
Sitting with a towel/strap positioned exactly as taught by the clinician.
2
Set the contact
The towel supports the selected segment while the hands guide the direction of the self-glide.
3
Apply the technique
Maintain the gentle glide while actively rotating; stop before pain, dizziness or neurological symptoms.
4
Dose & re-test
5–10 repetitions, symptom-guided. Re-test: Pain-free rotation immediately after the self-SNAG.
Clinical pearl
Teach self-SNAG only after a clinician has confirmed the direction is helpful and the patient can reproduce it correctly.
Safety / avoid
Stop with dizziness, unusual headache, visual symptoms or distal neurological change.
Safety / do not apply when…
Stop with dizziness, unusual headache, visual symptoms, neurological change.
Clinical rule
A technically correct technique is not automatically a useful technique. Keep it only when the patient's pain, range or function improves in a clinically meaningful way, then transfer that gain into active movement, loading or self-management.
