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

	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
