Abstract
Background: AI-based biomechanics analysis integrating computer vision and machine learning is transforming motion analysis from laboratory-based marker systems to scalable, markerless real-world video assessment using standard inputs.
Methods: This article examines the technological foundations and the translation of kinematic pose data into mechanical insights via force vector orientation, torque distribution, and kinetic chain coordination within the MMSx framework.
Validation: We evaluate reliability challenges associated with markerless analysis, highlighting typical MAE ranges and the future integration of multimodal sensor fusion including wearables and force systems.
Conclusion: AI software significantly expands access to movement science but depends on rigorous validation and integration with established biomechanical principles governing human movement.
