Table 2 Correlations of assessments of postural sway assessed with a force plate (FP) and with an inertial measurement unit (IMU)

From: Coherence and reliability of a wearable inertial measurement unit for measuring postural sway

  Medio-lateral (FP vs. IMU) P-value Bias (mm/s) LOA (mm/s) Anterior–posterior (FP vs. IMU) P-value Bias (mm/s) LOA (mm/s)
EC (N = 32) 0.88 0.001 − 0.93 − 4.33 to 2.47 0.81 0.001 − 3.20 − 8.94 to 2.54
EO (N = 32) 0.84 0.001 − 1.29 − 3.59 to 1.01 0.71 0.001 − 2.74 − 7.02 to 1.54
