Frequency components of the normalized flow rate at the six axial locations along the spine for the ALS (red) and the healthy control (blue) groups. In each panel, the harmonics are divided by the dotted line and are presented from the first to the seventh harmonic. Significant harmonics are marked with asterisk at the respective harmonics as analyzed with the Mann–Whitney U test. The first, second, sixth, and seventh harmonic of T11–T12 are significantly different (p = 0.0031, p = 0.0136, p = 0.0097, and p = 0.0330), and at L3–L4 for the sixth harmonic (p = 0.0330)
