What our clients say:
I used to do running analysis with 2D video and software that required me to mark joints at specific moments in the gait cycle to estimate angles. I really appreciate being able to collect and visualize full kinematics time series with the same 2D video and built-in analysis with Model Health. I'm developing a new running analysis program using Model Health and I'm confident that the ability to provide more comprehensive data will set me apart and allow me to provide much better results to the runners I work with

Model Health has been a huge boost to our small private practice. We have been able to implement it mainly with 3D running gait analyses as well as incorporate it into our ACL return to sport testing workflows. The set-up is quick, data collection is seamless, and the data processing continues to get faster. The reports that it generates are accurate, consistent, and are high quality for kinematic data, with easy-to-understand visualizations for joint angles and key metrics.
Alex Peters
Sports Physical Therapist at Impulse PT
Using this system in my clinic has been a game change. It provides clear, actionable insights into movement patterns, helping me make more informed decisions for my patients' treatment plans. The accuracy and ease of use make it an invaluable tool for improving patient outcomes.

Model Health's ability to quickly understand our needs, combined with their responsiveness, make our collaborations particularly effective!
Decathlon
R&D and QA developer at Decathlon
It's been great to implement Model Health in our clinic. It challenges our thoughts and gives us a way to objectively look at movements for those with challenging lingering pain when strength, Range Of Motion, and structure are "healthy". Especially useful for those working with athletes where we are unable to "see" high speed movements

High-Performance Sports Physical Therapist at Stanford Athletic
We’re excited to integrate this innovative motion analysis into our ACL pathway at the POSM Performance Lab. This technology allows us to quantify contact time, RSI, and knee and hip joint kinematics during the triple hop test, providing a more comprehensive assessment of capacity following ACL injury.

FAQs
This FAQ covers the questions we’re asked most often. Haven’t found what you are looking for? Our team is here to help.
What devices do I need to use Model Health?
You need at least 2 iOS devices (iPhones, iPads, or iPods released in 2018 or later), tripods with phone holders, and a printed checkerboard calibration board mounted on a flat surface.
Is there a free trial?
Yes — you can sign up for a 30-day free trial at app.modelhealth.io. Visit modelhealth.io for information on subscription plans.
Where can I download the mobile app?
The Model Health iOS app is used to record activities and is entirely controlled by our web app. The iOS is available on the App Store and runs both on iPhone and iPads — search for "Model Health" or use this direct link.
What browsers does the web app support?
Our web app is optimized for laptops and tablets. On laptop, the web app works best on Google Chrome (recommended), Firefox, Safari, and Edge.
On iPads, Safari is recommended. One Android tablets, Google Chrome is recommended.
Do I need a stable internet connection?
Yes. Both the iOS app and the web application require a stable internet connection to function properly.
What types of movements can Model Health capture?
The system is designed for a wide range of activities — overground and treadmill gait, single-leg tasks, postural sway assessments, and change of direction. As long as the participant stays within the cameras' field of view, most functional movements can be captured. For a specific set of 12 movements, we support advanced analysis and automated metric extraction.
What does the output look like?
Model Health produces full-body kinematics using a scientifically validated musculoskeletal model with 36 degrees of freedom, covering joints from the ankle and subtalar up through the hip, lumbar spine, shoulder, and elbow. The model is built on OpenSim, a widely used open-source platform in biomechanics research.
How accurate is it compared to traditional motion capture?
Model Health is built on markerless technology, eliminating the need for reflective markers while still generating biomechanically meaningful joint kinematics. The technology builds on OpenCap, developed by our co-founders at Stanford University. For detailed accuracy benchmarks, consult our validation papers: first article and second one.
