Figure 1.

Proportions of pathological clinical, neurological, and neurophysiological assessments in patients without and with T2w hyperintense lesion in MRI. (A) Proportions (%) of pathological clinical assessments (i.e., total mJOA and mJOA subscores) are illustrated in patients without (left side) and with (right side) T2w hyperintense lesion in MRI. (B) Proportions (%) of pathological neurological assessments (i.e., upper and lower extremity motor and sensor function) are shown for both groups. (C) Proportions (%) of pathological neurophysiological assessments (i.e., segmental and below level contact heat evoked potentials) are shown for both groups. Red colors represent motor assessments (i.e., integrity of the corticospinal tract), blue colors represent large fiber sensory assessments (i.e., integrity of dorsal columns), and yellow colors represent small fiber sensory assessments (i.e., integrity of the spinothalamic tract). The darker colors represent lower scores/pathological assessments (i.e., more impairments). Differences between groups (^*p < 0.05; ^**p < 0.01) was shown for the mJOA subscores for upper and lower extremity motor function (A) and monofilament sensation (B), but not for other assessments. mJOA, modified Japanese Orthopedics Association score; UE, Upper extremity; LE, Lower extremity; CHEPs, Contact heat evoked potentials; and M.filament, monofilament.
