Article Title: A Comparison of Inertial Measurement Unit and Motion Capture Measurements of Tibiofemoral Kinematics during Simulated Pivot Landings

doi: 10.3390/s22124433

Figure Lengend Snippet: Mean (SD) values for Bland–Altman comparisons of peak angular velocity from Certus and IMUs for the three planes. On average, the Certus measurements tended to overestimate the IMU measurements. The percentage difference (Diff [%]) is defined in the table footnote.

Article Snippet: Due to the fact that the LoAs ranged from 35.9% to 49.8% of the measured joint angle, the APDM IMUs could not reliably measure the sudden changes in joint angles that occur during simulated pivot landings, even in the absence of soft tissue artifact.

Figure Lengend Snippet: The MS model segments whose inverse kinematics were calculated during performance tests, presented by the number of IMUs whose data was utilized.

Article Snippet: The subject was instructed to take the standard anatomical position at the beginning of each trial to calibrate the IMUs on the musculoskeletal model as per the standard IMU calibration procedure of OpenSim (elaborated in ).

Figure Lengend Snippet: The execution times are presented as mean over 10 trials for two different musculoskeletal models (lower body and torso model and full-body model) using one, seven, or 12 IMUs. IMU quaternions orientations were retrieved from previously recorded walking trials. Red diagonal cross: lower-body model and laptop computer. Green cross: full-body model and laptop computer. Blue circle: lower-body model and desktop computer. Purple square: full-body model and desktop computer.

Figure Lengend Snippet: The throughputs are presented as mean over 10 trials. The measurements were repeated with two different musculoskeletal models, and using one, seven or 12 inertial measurement units (IMUs). IMU quaternion orientations were retrieved from previously recorded walking trials. Red diagonal cross: lower-body model and one IMU. Green cross: lower-body model and seven IMUs. Blue circle: full-body model and one IMU. Purple square: full-body model and seven IMUs. Cyan diamond: full-body model and 12 IMUs.

Figure Lengend Snippet: The values are calculated over 10,000 IK operations for two different musculoskeletal models, two different computers and one, seven or 12 inertial measurement units (IMUs). Randomly selected unit quaternions were used as IMU orientations. Red diagonal cross: lower-body model and laptop computer. Green cross: full-body model and laptop computer. Blue circle: lower-body model and desktop computer. Purple square: full-body model and desktop computer.
