📖 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 Lateral Flexion
Thoracic Intervertebral Joints • Thoracic Spine • frontal plane
Side bending of the thoracic spine. Coupled with rotation.
Axis: anterior-posterior
Normal Range of Motion
No single accepted goniometric norm for isolated thoracic lateral flexion; AAOS publishes only combined thoracolumbar lateral flexion (~35 degrees each side). Magee cites isolated thoracic lateral flexion of roughly 20-40 degrees, typically measured by dual inclinometry or fingertip-to-floor distance. Value intentionally left null.
