📖 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.
Isolated Small-Finger Abduction
Positions & Range of Motion
- Start
- seated with the forearm and hand supported, fingers extended and the small finger held adducted alongside the ring finger, a rubber band or manual resistance across the finger
- End
- small finger abducted sideways away from the ring finger against the resistance and held ~3 s before controlled return
- Range of Motion
- 5th-MCP abduction from neutral to end range and back, isolated to the small finger
How to Perform
Abduct the small finger away from the ring finger against a rubber band or manual resistance. Targets ADM.
