How Accurate is Model Health

One of the most common questions we get about the Model Health platform is a simple one: How accurate is it?

Marker-based motion capture in a lab is the established gold standard for measuring 3D movement. Model Health captures the same data from smartphone video, without markers or specialist equipment. How closely the two agree is a good question to ask.

To answer it, Chris Polley, Sport Science Consultant, gathered the peer-reviewed evidence, our own validation alongside four independent research groups that tested the technology across return-to-sport tasks, pathological gait, and treadmill running, in different labs and populations.

The full overview brings it together in one place: the numbers, the studies, and the joint-by-joint detail.
