Milliseconds matter: Biomechanical inverse dynamics analysis is highly sensitive to imperfect data synchronization

In biomechanical inverse dynamics, small timing errors in data synchronization (such as between motion capture, force plates, or EMG systems) can significantly affect the accuracy of the calculated forces, moments, and joint kinetics. Since these analyses rely on precise temporal alignment of input data, even millisecond-level discrepancies can lead to incorrect estimations of forces and moments, which impacts the interpretation of movement mechanics, performance, and injury risk. Accurate synchronization ensures reliable results in understanding the forces acting on the body during motion.
