📖 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.

Everything else — the body map, progression ladders, coverage heatmap, exercise finder, and all anatomy/exercise/source pages — works fully. The full app (live search + API + database) runs from the source on GitHub.

Isometric Neck Strengthening (4 Directions)

Draftstrength90%beginner⬤ strong evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
seated tall with a neutral cervical spine, a hand/palm placed against the forehead, side, or back of the head
End
cervical muscles contract to match a steady manual resistance in flexion, extension, lateral flexion, and rotation while the head stays still, upper traps quiet
Range of Motion
isometric hold — minimal to no cervical joint excursion in each of the four directions

How to Perform

Manual resistance or hand-resisted cervical flexion, extension, lateral flexion, and rotation without movement. Thera-Band resistance produces 3.8-15.7% MVIC flexion and 20.2-34.8% MVIC extension. Programs >20 reps/session and >8 weeks duration show significant pain and disability improvements.

Coaching Cues

  1. 1

    Long neck, jaw soft — match force without moving

    (verbal)
  2. 2

    Press your forehead into your palm; the palm doesn't move

    (verbal)
  3. 3

    Resist a steady push from each side, front, and back

    (verbal)
  4. 4

    Self-palpate upper traps — they should stay quiet

Evidence-Based Dosing & EMG Data

Recommended Dosing

3×10 reps each direction with 5-10 second holds, >20 reps/session, >8 weeks duration [Yang 2022]

EMG Activation Data

Thera-Band: flexion 3.8-15.7% MVIC, extension 20.2-34.8% MVIC. Cybex: flexion 20.9-83.5%, extension 40.6-95.8% [Burnett 2008]

Muscles Involved (4)

Primary Movers

Deep Cervical Flexors— Flexion direction
Erector Spinae Group— Extension direction — thoracic portion

Secondary Movers

Sternocleidomastoid— Superficial flexor — activity decreases with training [Dirito 2024]

Stabilizers

Upper Trapezius— Scapular stability during resistance

Easier Variations ↓

1

Submaximal Resistance

Use only 25-50% effort against your hand. Build tolerance before increasing force.

2

Supine Isometrics

Perform lying down to reduce postural demands.

Harder Variations ↑

1

Thera-Band Resistance

Use resistance band for consistent progressive loading across all directions.

2

Cybex/Machine Resistance

Machine-based resistance for higher activation (up to 95.8% MVIC) [Burnett 2008].

Research Notes

AUDIT[medium]: Specific %MVIC EMG values (Thera-Band flexion 3.8-15.7%, extension 20.2-34.8%; Cybex up to 95.8%) and the dose-response claim (>20 reps/session, >8 weeks) are attributed to Burnett 2008, Yang 2022, and Dirito 2024, but none of these are in the linked sources (only Kisner, ACSM). → Add Burnett 2008, Yang 2022, and Dirito 2024 to linked sources, or remove the specific quantitative claims that cannot be cited.
