📖 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.
Thumb Opposition Exercise
Positions & Range of Motion
- Start
- seated, forearm supported, hand open with fingers extended and thumb in neutral abduction
- End
- thumb pad rotated and touched firmly to each fingertip in sequence forming a clean O, then reversed back through the sequence
- Range of Motion
- full thumb opposition arc (rotation plus flexion) from open hand to pad-to-pad contact with each of the four fingers
How to Perform
Touch the thumb to each fingertip in sequence, then reverse. Trains opposition coordination used in fine motor tasks.
