Markerless detection of compensatory movement: validation data and analysis code

Repetition-level data, clinician annotations and analysis code behind the paper Markerless On-Device Detection of Compensatory Movement Patterns in Upper-Limb Rehabilitation Exercises from Monocular RGB Video: A Validation Study in Healthy Adults. Contains 913 repetitions from 27 healthy adults in two non-overlapping cohorts (18 for detection validation, 9 for threshold calibration), 1242 independent annotations from two clinicians blind to the instructed condition, the calibrated thresholds, and a self-verifying script that recomputes every number reported in the paper. Video recordings and per-frame keypoint series are not included; the consent obtained does not cover their public release.
