The database that didn't exist yet

Babon is building a large, labelled clinical motion database. The figures below come live from the research database.

LiveRecordings in database43.366Aggregated from public, CC-BY licensed datasets. Base layer for normative comparison and validation.
Unique subjects351Counted where the source records a subject id; AddBiomechanics does not. From practices and clinics: not yet.
Data sources5Three public datasets, all CC-BY licensed and fully attributed, plus two of our own education series.

Why this database

Context

A large, representative clinical motion database from everyday practice does not currently exist. The only conventional source is a gait lab, where a single measurement costs tens of euros. As a result, analyses like age-norms, recovery patterns after knee surgery, and diagnosis-specific reference data are simply not feasible in practice.
