A Major Research Milestone for Theia3D
More than 50 independent, peer-reviewed research publications now cite, evaluate or review Theia3D across domains including gait, sports performance, postural control, upper-extremity movement and other biomechanics applications. These publications are available in world-leading journals including Journal of Biomechanics, Journal of Applied Biomechanics, Gait & Posture and Clinical Biomechanics. Together, they represent a growing body of evidence across different movements, populations and environments, reinforcing Theia3D’s position as the most extensively validated markerless motion capture system.
Beyond The Radar Gun: How Dean Jackson uses Theia3D For Incremental Velocity Analysis
This article is a first in a miniseries that breaks down what motion capture can show beyond radar, ball data, and standard video. In this first installment, Dean breaks down how he uses Incremental Velocity Analysis, or IVA, to study what changes biomechanically as pitchers move closer and closer to max output.
New Research on Theia3D: Comparing Markerless and Marker-Based Shoulder Kinematics Across Full Arm Range of Motion
A 2025 study published in the Journal of Biomechanics compared shoulder kinematics measured with Theia3D markerless motion capture against gold-standard marker-based motion capture across full arm ranges of motion. The results show strong agreement for many movements, particularly in the coronal plane, while also highlighting where caution is still required, especially at the extremes of ranges of motion and in transverse-plane rotations.

Summary

This blog post outlines our approach to R&D and includes links to many peer-reviewed articles using or citing Theia3D.

New Research on Theia3D

We’re excited to share some of the latest peer-reviewed research using Theia3D markerless motion capture, as well as an exciting new development in our product roadmap!

New Validation Research

New research has been published comparing Theia3D’s markerless motion capture output against established marker-based reference systems for gait biomechanics research. The findings contribute to the growing evidence base supporting Theia3D’s use across diverse research populations and movement tasks.

Key themes from recent publications include:

  • Strong agreement for sagittal-plane lower extremity kinematics during walking and running
  • Reliable performance across diverse research populations including aging adults and pediatric participants
  • Feasibility for community-based and applied biomechanics research settings outside traditional laboratories

Looking Forward

We continue to expand our validation evidence base across new movement types, research populations, and deployment environments. Each new peer-reviewed study strengthens the foundation for confident use of Theia3D in biomechanics research and performance applications.
