Assumptions made for each body part to correct the magnetic north in the MH-IMU configuration.

IMU Sensor	Axis Projected on the Ground	Angle with the Y-Axis of the Pelvis Projected on the Ground [°]
Head	X	90
Arm	Y	90
Forearm	X	90
Hand	X	90
Chest	Y	0
Thigh	Y	90
Calf	Y	90
Foot	Y	0

The axes mentioned are those represented in Figure 3, considering that the participants had adopted the Fitbody position for the MH-IMU configuration represented in Figure 5.
