Implication

Randomized trial compares joint angles during stair ascent using portable IMUs and optical tracking, indicating accuracy of IMUs.

Key Points

This study aims to compare anatomical joint angles collected via inertial measurement units (IMUs) with those obtained from an optical tracking device during stair ascent.
Measured anatomical joint angles of the thigh, knee, and ankle using IMUs and an optical tracking device in fourteen healthy subjects.
Calculated the root mean square error (RMSE) and Pearson correlation coefficient (r) to evaluate joint kinematics between the two devices.
Mean correlation coefficients between the two devices ranged from 0.93 to 0.99, indicating strong agreement.
Average RMSE was found to be 4 degrees across all joint angles, suggesting IMUs are reliable for measuring anatomical joint angles.
