📖 Static demo — read-only snapshot

You’re browsing a static build of the Body IQ knowledge graph, so everything loads with no backend. A few things that need the live server are turned off here:

  • Global search (sidebar) is disabled — it queries the API.
  • The JSON API and the API “Try it” playgroundaren’t included.
  • The data is a snapshot — it refreshes only when the demo is rebuilt, not live from the database.

Deep Neck Flexor Training (Chin Tucks with Pressure Biofeedback)

Draftmotor-control90%beginner⬤ strong evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
supine, knees bent or legs extended, head neutral, pressure biofeedback cuff behind the neck inflated to baseline (~20 mmHg)
End
gentle craniocervical nod (chin tucked, back of neck lengthened) raising cuff pressure toward 22–30 mmHg and held ~10 s without superficial neck-flexor substitution
Range of Motion
small craniocervical flexion (a subtle head nod), held isometrically at graded pressure targets

How to Perform

Craniocervical flexion exercise targeting the deep cervical flexors (longus colli, longus capitis). Patient lies supine with a pressure biofeedback unit behind the neck and performs graded chin tuck contractions (22-30 mmHg). Improves neck pain, posture, and muscle endurance while increasing deep flexor cross-sectional area.

Coaching Cues

  1. 1

    Soft chin nod — back of neck quietly lengthens

    (verbal)
  2. 2

    Float the gauge needle from 22 toward 30 mmHg

    (verbal)
  3. 3

    Hold the gauge steady for 10 seconds, then release

    (verbal)
  4. 4

    Palpate the front of your neck — it stays soft

Evidence-Based Dosing & EMG Data

Recommended Dosing

10 reps × 10-second holds at each pressure level (22-30 mmHg), 2x daily for 6 weeks minimum

EMG Activation Data

Linear EMG-pressure relationship (22-30 mmHg); longus colli 17.4% CSA increase at C2-C3 [Falla 2003, Cagnie 2010]

Muscles Involved (3)

Primary Movers

Deep Cervical Flexors— Longus colli and longus capitis — the target muscles

Stabilizers

Sternocleidomastoid— Should be minimally active — overuse indicates compensatory pattern

Lengthened / Stretched

Semispinalis Capitis— AUDIT: Craniocervical flexion's defining antagonist is the posterior capital extensor group; semispinalis capitis (largest) is elongated as the back of the neck lengthens, per the exercise cue.

Easier Variations ↓

1

Supine Chin Tuck (No Biofeedback)

Perform the chin tuck motion lying down without a pressure gauge. Focus on the subtle 'nod' without lifting the head.

2

Seated Chin Tuck

Perform seated against a wall for tactile feedback. Less precise than biofeedback but more accessible.

Harder Variations ↑

1

Graded Pressure Holds

Progress through 22, 24, 26, 28, 30 mmHg targets with 10-second holds at each level, 10 repetitions.

2

Chin Tuck with Head Lift

After achieving 30 mmHg, maintain the tuck while lifting the head slightly off the surface. Combines deep flexor activation with anti-gravity endurance.

3

Progress to supine-chin-tuck-liftoff

AUDIT: Once the patient holds 30 mmHg CCF with minimal SCM activity, adding anti-gravity head liftoff is harder; DNF's named 'Chin Tuck with Head Lift' progression IS the supine-chin-tuck-liftoff node. Distinct roster nodes.

Research Notes

Addresses forward head posture and hypertonic superficial neck muscles common in sedentary workers. With biofeedback, enhances motor control. Evidence: craniocervical flexion exercises improve pain, posture, and deep flexor muscle cross-sectional area [Amiri Arimi 2017, Sun 2024]. AUDIT[low]: The specific hypertrophy claim 'longus colli 17.4% CSA increase at C2-C3' is attributed to Falla 2003 and Cagnie 2010 (Falla PMID appears only in cue text); neither Falla 2003 nor Cagnie 2010 is in the linked sources array. → Add Falla 2003 (PMID 12506816) and Cagnie 2010 to linked sources for the CSA claim.
