Accelerometer Data Harmonization and Feature Engineering for Gait Analytics

Gait analytics is utilized for a wide range of health-related applications, ranging from fitness tracking to medical diagnostics, and beyond. Inertial measurement units that are ubiquitously available in mobile devices provide an accessible means of gait analysis but differences in sensor specifications, placement, and recording protocols limit comparability across studies. This study developed and evaluated an analysis-centered data warehouse and standardized quality-assessed processing pipeline to facilitate the integration and joint analysis of heterogeneous gait accelerometer data.
