FIGURE 6:

Cervical spinal cord structural magnetic resonance imaging. (A) Two axial slices obtained from the C2 level in individuals with (Modified Ashworth Scale [MAS] = 4) and without (MAS = 0) spasticity. Images show the spinal cord area (SCA, green), left to right width (LRW, yellow), anterior to posterior width (APW, yellow), and cerebrospinal fluid (CSF, blue). (B) Boxplot charts show the group data (controls, n = 13; nonspastic spinal cord injury [SCI], n = 9; spastic SCI, n = 12). The abscissa shows the groups tested (controls = blue bar, nonspastic SCI = green bar, spastic SCI = red bar). The ordinate shows the SCA (in square millimeters, upper graph), LRW (in millimeters, middle graph), and APW (in millimeters, lower graph). The top and bottom lines of the boxes correspond to the 95% confidence interval and the lines in the boxes correspond to the median. The 2 bars extend from the maximum to the minimum value. *p < 0.05, **p < 0.01, ***p < 0.001. A = anterior; I = inferior; L = left; P = posterior; R = right; S = superior.
