Biomechanics-informed inertial tracking achieves the accuracy of marker-based kinematics

A biomechanics-informed sensor-fusion method improves inertial measurement unit tracking to rival laboratory marker-based motion capture accuracy for lower-extremity kinematics.

Key Takeaways
  • Please note there may be errors present which affect the content, and all legal disclaimers apply
  • Yet, their accuracy is perceived as inferior to that of marker-based systems
  • Movement scientists have been anticipating the leap out of the laboratory with cautious optimism
