Figure 3From: The correlation between motor impairments and event-related desynchronization during motor imagery in ALS patientsLongitudinal analysis of correlation between bulbar scale and ERD in individuals. A: 2 ALS patients. B: 2 controls. In ALS patients, disease duration and bulbar scale were negatively correlated. Bulbar scale and ERD were also negatively correlated. For controls, reproducibility of ERD was high and absolute ERD were larger than those of ALS patients.Back to article page
