📖 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.

Thoracic Extension/Rotation Mobilization

Draftmobility85%beginner⬤ moderate evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
sidelying, hips and knees stacked and bent ~90°, both arms extended together in front at shoulder height, pelvis anchored
End
top arm rotated open toward the wall behind, chest and gaze following the hand across the ceiling into thoracic extension/rotation while hips stay fixed
Range of Motion
thoracic rotation to comfortable end range (~open-book to ~90° trunk rotation), lumbar/pelvis held still

How to Perform

Active mobility exercises targeting thoracic spine extension and rotation. Includes open book rotations in sidelying, quadruped thoracic rotation, and seated rotation with overpressure. Significantly improves thoracic kyphosis angle, cervical extension, and pain. More effective than cervical-only interventions for forward head posture.

Coaching Cues

  1. 1

    Quiet hips — rotation lives in the mid-back

    (verbal)
  2. 2

    Open the top hand toward the wall behind you

    (verbal)
  3. 3

    Eyes follow the hand across the ceiling

  4. 4

    Knees stacked — pelvis is the anchor

Evidence-Based Dosing & EMG Data

Recommended Dosing

3×10 reps each direction, daily

Muscles Involved (4)

Primary Movers

Erector Spinae Group— Thoracic portion drives extension
Multifidus— Segmental rotation control

Secondary Movers

Internal Oblique— Ipsilateral rotation
External Oblique— Contralateral rotation

Easier Variations ↓

1

Supine Trunk Rotation

Lie on back with knees bent, gently drop knees side to side. Gravity-assisted with less demand.

2

Cat-Cow with Rotation

In quadruped, combine cat-cow with gentle rotation by reaching one arm to the ceiling.

Harder Variations ↑

1

Seated Rotation with Overpressure

Sit straddling a bench, arms crossed. Rotate and use opposite hand on knee for gentle overpressure at end range.

2

Half-Kneeling Thoracic Rotation

Half-kneeling with hands behind head. Rotate toward the front knee. Challenges hip-thoracic dissociation.

Research Notes

Evidence: thoracic mobilization significantly improves kyphosis angle, cervical extension, and pain [Cho 2017, Feng 2018]. More effective than cervical-only interventions for forward head posture [Cho 2017].
