Group differences for voxel-wise FA contrast (12 cervical dystonia patients versus 12 matched controls).

*Met significance criteria (p†p value was within an order of magnitude of the corrected threshold (a trend).Positive t values indicate FA values were elevated in cervical dystonia patients relative to control subjects; negative t values indicate FA values were reduced in cervical dystonia patients relative to control subjects. L = left hemisphere; R = right hemisphere; wm = white matter.
