Typical IMUs recording for a) TUG and b) 18 mW of a p-iNPH subject acquired at T24 h. Heel strikes (downward triangles) and foot offs (upward triangles) are superimposed on top of shoes medio-lateral angular velocities (right in green and left in red); as well, starts (rightward triangles) and ends (leftward triangles) of sit-to-stand and stand-to-sit phases are shown (when present) on the antero-posterior inclination (in blue) recorded from the sensor placed on lower back
