Digital Health, Smartphone-Based Motor Assessment, and Public Health

The availability of technologies for assessing people's health is a limiting factor in many countries, especially the poorest ones. Smartphones offer a range of tools that can be useful for extracting biological signals that may be related to individuals' health conditions or diseases. Among these tools, inertial sensors and touchscreens enable the performance of motor tests that scientific literature has shown to be valid for the physical assessment of individuals. The integration of smartphones into public policies aimed at increasing health monitoring of individuals would allow for the expansion of the scope of quality assessment and preventive actions against functional declines.
