Figure 9.

(A) absolute and (B) normalized differences between peak $\left|\omega \right|$ timings measured simultaneously by the reference IMU and the misplaced IMU (red represents anterior- or left-proximal misplacement; purple represents posterior- or right-proximal misplacement). The white line represents the mean observed difference across trials (bias), the dark-colored box represents the confidence interval about the mean (±1.96 SEM), the light-colored box represents the limits of agreement (±1.96 SD), and the grey dots represent trials falling outside the limits of agreement (with trials falling outside the axis limits plotted at the limit). Positive differences indicate the misplaced $\left|\omega \right|$ peak occurred after the reference peak, while negative differences indicate the misplaced $\left|\omega \right|$ peak occurred before the reference peak.
