| Sumario: | The article focuses on the establishment of global standards for wearable technology to measure mobility in aging populations. It emphasizes the need for a shared conceptual framework with harmonized definitions to treat mobility as a coherent construct, alongside validated metrics linked to clinically meaningful endpoints for effective clinical use. The integration of contextual information and the development of robust reference data, both cohort-based and individual longitudinal, are highlighted as essential for accurate interpretation of real-world mobility data. These elements aim to transform digital mobility assessment from a technological innovation into a clinically actionable tool for older adults.
