📖 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 with the hand resting, wrist straight, a rubber band looped around all five fingertips with fingers and thumb drawn together
End
fingers and thumb spread wide apart against the band's resistance, open shape held ~2 s
Range of Motion
full finger and thumb abduction/extension from closed to maximally spread against resistance

How to Perform

Place a rubber band around all five fingertips and spread the fingers apart against resistance. Targets finger and thumb extensors for grip balance and hand rehabilitation.

Coaching Cues

  1. 1

    Long, straight wrist — extensor digitorum opens the hand

    (verbal)
  2. 2

    Spread the fingers wide against the band

    (verbal)
  3. 3

    Hold the open shape for two seconds before releasing

    (verbal)
  4. 4

    Band sits at the fingernail line, not the knuckles

Evidence-Based Dosing & EMG Data

Recommended Dosing

3×15-20 reps, 2-3x daily

Muscles Involved (5)

Primary Movers

Extensor Digitorum— Finger MCP extension against band resistance

Secondary Movers

Dorsal Interossei (Hand)— Finger abduction component

Lengthened / Stretched

Flexor Digitorum Superficialis— AUDIT: Primary MCP finger extension against the band puts the long finger flexors on stretch; FDS is the direct antagonist to extension.
Flexor Digitorum Profundus— AUDIT: Finger extension lengthens the deep finger flexor across the MCP/IP joints; FDP is antagonist to the extension action.
Palmar Interossei— AUDIT: The finger-abduction component (spreading fingers against the band, a listed movement) stretches the palmar interossei, the finger adductors.

Easier Variations ↓

1

Thinner Band

Use a lighter rubber band for less resistance.

Harder Variations ↑

1

Double Band

Add a second rubber band for increased resistance.
