📖 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.
Shoulder Adduction
Glenohumeral Joint • Shoulder • frontal plane
Return of the arm toward the body in the frontal plane.
Axis: anterior-posterior
Normal Range of Motion
AAOS and Norkin & White do not publish a separate adduction norm (return to neutral from abduction is 180-0). When measured as adduction anterior to the trunk, commonly cited normals range 30-50 degrees; 45 degrees is the most frequently cited value.
