The fatty infiltration of the multifidus muscle was
investigated in 31 individuals with chronic Whiplash
Associated Disorders (WAD) and 31 controls, matched for
age and sex in C4-C7, using water-fat separated MRI.
Individuals with severe disability had significantly
(p=0.03 to 0.04) higher content of fatty infiltration on
the right side of the neck compared to controls and to
those with mild/ moderate WAD. There were no significant
differences between those with mild/ moderate WAD and
healthy controls. Earlier reported findings using
T1-weighted MRI was reproduced also using water-fat
separated MRI.
