PAINT
The measurement framework: Position, Area, Intensity, Nature, Time.
How it works
Position, Area, Intensity, Nature, and Time — captured on an anatomy-classified 3D body surface, measured in real square millimeters, and exported as structured records. Explore the model below.
Drag to rotate · toggle Male / Female · switch the overlay (regions, subregions, texel grid, texel size).
The framework
Anchors each symptom to where it sits on the body — on a 3D model you can pose to match the patient, with that posture recorded alongside the chart.
Measures how much body surface is involved, in real cm² and percent BSA on the reviewed 3D mannequin.
Keeps symptom strength attached to the painted surface so the PAIN-Index is not flattened into presence versus absence.
Preserves the qualitative character of the symptom so burning, aching, pressure, or numbness remain distinguishable.
Tracks how a symptom changes across snapshots — whether it persists, spreads, resolves, or recurs — so reassessment asks where it is better, worse, new, or resolved.
The T in PAINT
Each visit is a PAINprint Snapshot. Stack snapshots and you get a PAINprint Timeline — the symptom story over time. Trajectory is how that story moves: spreading, shrinking, intensifying, resolving, or recurring. That is the difference between asking "where does it hurt?" and "where did it hurt, how much, what kind, and what changed?"
The measurement framework: Position, Area, Intensity, Nature, Time.
The painted spatial record for one finding at one moment.
A time-stamped chart state composed of one or more PAINprints.
An ordered sequence of Snapshots — the symptom story over time.
A normalized impact score derived from measured area × reported intensity.
(weighted area / total BSA) × 100Derived objects
Beyond the exports, every capture yields a derived metric panel, a snapshot, and — stacked over time — a PAINprint Timeline. Examples are simulated and de-identified.

Every output derives from one finding-level model. Examples are simulated and de-identified — they show the structure, not real patient data.
