📖 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.

View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
seated at a table, pegboard and pegs within reach, forearm supported, fingers ready in a precision pinch
End
individual pegs picked up with a thumb–index pinch and placed one at a time into target holes, repeated at a controlled accurate pace
Range of Motion
fine distal motion — thumb/finger pinch-and-release with small wrist and forearm positioning movements; minimal proximal joint excursion

How to Perform

Task-specific manipulation of pegs, pins, or small objects into target holes. Used as both assessment and training.

Evidence-Based Dosing & EMG Data

Recommended Dosing

10–15 minutes, 3–5×/week.

EMG Activation Data

Task-specific training more effective than general exercises for functional outcomes after peripheral nerve injury [Hsu 2019; Chen 2022].
