(A) Box-and-whisker plot showing the anatomic connectivity
values of the left thalamo-motor pathway in healthy controls and patients with
chronic low back pain. The open circles indicate the anatomical connectivity
strengths of the left thalamo-motor pathway in both groups. The upper and lower
edges of the box mark the 25th and 75th percentiles. The
error bars represent the 95% confidence level. (B) Group
differences of the anatomical connectivity in the left thalamo-motor pathway
revealed by cluster-wised diffusion tensor imaging tractography. HC, healthy
controls; CLBP, chronic low back pain; R, right. mm, millimeter;
“X”, “Y”, and “Z” are Montreal
Neurological Institute (MNI) coordinates, representing sagittal, coronal and
axial views, respectively.
