Effects of Stroke Lesions on Spasticity in Stroke Patients


Overlay of lesions in all the subjects with stroke (n = 45)



Statistical voxel-based lesion-symptom mapping for upper limb spasticity

The non-parametric Brubber Munzel statistical analysis was used for the continuous severe post-stroke upper limb spasticity. Color scale indicates Brunner–Munzel rank order z-statistics. Only voxels significant at P<0.05 are shown. Colored bar represents the z statistics. 

The statistical map is displaying voxels with a minimum Z score of 2.4083. This matches the false discovery rate threshold. We set the maximum range of the Z score as 6, which are shown as being the maximum brightness.
