Cervical Motor Control Test (Craniocervical Flexion Test): How to Assess It

Not all neck pain comes from "having a stiff neck": in many cases, the underlying cause is that the deep neck flexors (longus colli, longus capitis) aren't doing their job, and other muscles (sternocleidomastoid, scalenes) end up taking on tasks that aren't theirs. The craniocervical flexion test (CCFT), or cervical motor control test, is designed precisely to detect this.

It's one of the most commonly used tests in physiotherapy to assess cervical motor control dysfunction in people with chronic mechanical neck pain.

What does this test measure?

The CCFT assesses the ability to activate and sustain a low-intensity contraction of the deep neck flexors (the muscles that produce a gentle "nodding" motion, like a small "yes" with the head), without excessive compensation from the superficial neck flexors (sternocleidomastoid, scalenes).

It's traditionally performed using a pressure biofeedback device (an inflatable cuff placed under the neck), although a simpler version without the device can also be done, observing movement quality and muscle activation.

Equipment needed

• Ideally, a pressure biofeedback unit placed under the cervical curve
• A treatment table
• Alternative without a device: your hands to palpate sternocleidomastoid activation and observe the movement pattern

Step-by-step protocol

1. The client lies supine, with the head in a neutral position
2. If using biofeedback, place the cuff under the cervical curve and inflate it to a baseline reference pressure (usually around 20 mmHg)
3. Ask the client to perform a gentle craniocervical flexion movement (like a small "nod," without lifting the head off the table or flexing the whole neck)
4. If using biofeedback, the goal is for the client to be able to progressively increase the pressure in 2 mmHg increments (from 20 up to 30 mmHg), holding each level for a few seconds
5. Without biofeedback, observe whether the movement is smooth, controlled, and localized to the upper neck, or whether there's excessive tension in the sternocleidomastoid/scalenes, shoulder elevation, or a "block" movement of the whole head
6. Note the pressure level (or movement quality) the client can reach without obvious compensations

Common mistakes

• Allowing the client to "force" the movement with the whole neck instead of a smooth, localized one
• Not detecting compensatory sternocleidomastoid activation, which is exactly what the test aims to identify
• Jumping straight to high pressure levels without progressing step by step

How to interpret the result

Result	Interpretation
Able to reach high pressure levels (28-30 mmHg) with predominant deep flexor activation and no excessive compensation	Good motor control of the deep neck flexors
Difficulty exceeding low levels (20-24 mmHg) without marked sternocleidomastoid/scalene activation	Suggests deep neck flexor motor control dysfunction, a common pattern in chronic mechanical neck pain
"Block" movement, with shoulder elevation or generalized tension	Global compensation, low ability to dissociate the craniocervical movement

This test isn't meant to give a "positive/negative" red-flag result, but rather to characterize a movement pattern that directly guides therapeutic exercise (specific training of the deep neck flexors).

Relationship with other tests

The CCFT pairs well with:

• Deep neck flexor strength test — one assesses motor control/quality, the other strength/endurance
• Forward head posture test — forward head posture and deep flexor dysfunction often go hand in hand

Why track this pattern

Improvements in cervical motor control aren't always obvious to the client, but they can be objectively measured with this kind of test. In Movalytics you can record the level reached on the CCFT (or a qualitative assessment of movement quality) at each session, and see how it progresses as specific cervical motor control work is incorporated.

Frequently asked questions

Do I need the biofeedback device to perform this test? It's not strictly necessary: you can do a qualitative assessment by observing and palpating the activation pattern, although biofeedback provides a more objective and reproducible measure. Does this test replace the deep flexor strength test? No, they're complementary: the CCFT assesses the quality and control of low-intensity movement, while the endurance test assesses the ability to sustain a contraction. Who is this test most useful for? Especially people with chronic mechanical neck pain, cervicogenic headaches, or a markedly forward head posture.
