Joint flexion/extension angle RMSE values for each task for joint angles calculated from optical data using Visual3D (V_OPT), IMU data using Visual3D (V_IMU), IMU data using Visual3D with calibration to align anatomical coordinate systems with optical model (V_IMU-CAL), and IMU data using MVN Analyze (X_IMU). Presented data are averaged between left and right sides across all participants and repetitions for each trial. RTK = run-to-kneel; RTP = run-to-prone; KTR = kneel-to-run; PTR = prone-to-run; KTP = kneel-to-prone; PTK = prone-to-kneel.
