📖 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.
Ankle Dorsiflexion
Talocrural Joint • Ankle • sagittal plane
Bringing the dorsum of the foot toward the shin.
Axis: medial-lateral

Talocrural dorsiflexion from neutral (foot at 90 deg to leg). AAOS and Norkin & White both cite 0-20 deg. Measured with knee flexed to relax gastrocnemius; value is reduced when knee is extended. PROM approximately equals AROM.
