Every data point in PRAXIS (mypraxis.health) carries a provenance tier indicating how it was captured. This makes source quality explicit for practitioners, report readers, referrers, and insurers.
| Tier | Marker | Definition | Examples |
|---|---|---|---|
| Gold | [G] | Clinician-administered or supervised measurement | Grip strength measured by physiotherapist; supervised 6-minute walk test; clinician-recorded range of motion |
| Silver | [S] | Device-derived from wearables or lab devices | Strava activity data; Garmin heart rate; wearable step count |
| Bronze | [B] | Self-reported, self-tested, or imported | Patient-entered sit-to-stand count; self-reported pain scale; imported historical data |
Reports use absolute test counts and shorthand markers [G], [S], and [B] to provide an audit-proof evidence basis. Provenance labelling does not refer to lower-tier data as "estimated" — it transparently identifies the capture method so readers can apply appropriate clinical weight.
Clinician certification can elevate confidence through attestation. Wearable and device data can complement clinician-measured tests because provenance labelling makes source quality explicit — interpretation stays defensible.
Finalised PRAXIS reports are sealed with a SHA-256 cryptographic integrity hash. The content, scores, observations, and provenance labels become immutable at finalisation. If a correction is needed, a new versioned amendment is created that explicitly supersedes the original. Both versions remain in the record with full attribution — who amended, when, and why.
Every access, edit, and status change is logged in an attributed audit trail.
PRAXIS measures functional capacity across five domains: Strength, Endurance, Power, Mobility, Balance. Each test result within these domains carries its provenance tier. These are the exact PRAXIS domain names — they are not interchangeable with the "5 pillars of human movement" model used elsewhere.
