📖 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.
Smooth Pursuit Tracking
Positions & Range of Motion
- Start
- seated upright, head still, both eyes fixed on a near target held 1-2 ft from the face
- End
- eyes having smoothly followed the target through its full slow excursion (~160° horizontal or ~120° vertical) without jerks or head turn
- Range of Motion
- oculomotor smooth pursuit through ~160° horizontal and ~120° vertical gaze excursion; head held stationary with no cervical motion
How to Perform
Follow a near target with both eyes as it moves slowly and steadily through ~160° horizontally and ~120° vertically, 1–2 ft from the face. Pursuit should be smooth — no jerks, no head turn.

Coaching Cues
- 1
Keep the head still — only the eyes move
(verbal) - 2
Track at a comfortable speed where pursuit stays smooth
(verbal)
Evidence-Based Dosing & EMG Data
2–3 horizontal sweeps + 2–3 vertical sweeps, 1–2×/day.
Muscles Involved (0)
No muscles linked.
Easier Variations ↓
Reduced Excursion
Use a smaller arc (60–80°) until pursuit stays smooth without symptoms.
Harder Variations ↑
Pursuit with Cognitive Load
Add a simple counting or naming task while tracking.
Research Notes
Used in BEEMS protocol for multiple sclerosis (twice weekly supervised) and post-concussion vision rehab [Hebert 2018; AAP/AAO 2022].
