Comparison of the FSMC motor score between the activity-dependent conduction block positive and negative groups. The motor scores of the Fatigue Scale for Motor and Cognitive Functions (FSMC) of activity-dependent conduction block (ADCB) positive and negative groups for patients with chronic inflammatory demyelinating polyneuropathy (CIDP) and spinal and bulbar muscular atrophy (SBMA). The box plot shows the median and IQR of the third and first quartiles. The notches in the box plots indicate the maximum and minimum values. In both the CIDP and SBMA groups, the ADCB-positive subgroup experienced more significant fatigue than the ADCB-opposing subgroups (CIDP; p = 0.0252).
