📖 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.
Saccadic Eye Movements
Positions & Range of Motion
- Start
- seated with head still and upright, two near targets held ~2 ft apart and 1–2 ft from the face (horizontal pair first, then vertical)
- End
- gaze rapidly and accurately refixated onto the opposite target with no drift or overshoot, head kept motionless throughout
- Range of Motion
- rapid horizontal then vertical saccadic eye excursions between targets; head/neck isometric with minimal joint excursion
How to Perform
Refixate the eyes rapidly between two near targets held ~2 ft apart, 1–2 ft from the face. Horizontal pairs first, then vertical. Aim for quick, symmetric, accurate jumps without overshooting.

Coaching Cues
- 1
Move only the eyes, keep the head still
(verbal) - 2
Eyes should land on the target — no drift, no overshoot
(verbal) - 3
If symptoms appear (nausea, fog), pause and rest before continuing
(verbal)
Evidence-Based Dosing & EMG Data
10–20 refixations × 2–3 sets per direction, daily.
Muscles Involved (0)
No muscles linked.
Easier Variations ↓
Larger Target Separation
Hold targets 3+ ft apart and farther from the face to reduce angular demand.
Harder Variations ↑
Saccades with Background Motion
Perform saccades against a moving visual background to add visual-vestibular conflict.
Research Notes
AAP/AAO endorse structured saccade training as part of combined oculomotor protocols after concussion. Evidence for saccade training in isolation in mTBI remains limited [Master 2022 Pediatrics; AAO 2022].
