Abstract

P300 event-related potential has been used as an instrument to establish the diagnosis of several disorders as well as to assess therapeutic outcomes. to investigate the relationship between stuttering amelioration and cerebral activity. P300 event-related potentials were obtained in three adult males, all stutterers, aged 20 to 31 years, pre and post-treatment, verifying changes in wave amplitude and latency between waves. results indicate a significant positive correlation between the reduction in the percentage of stuttered syllables and the improvement in wave amplitude for the right ear. stutterers can exhibit different patterns of interhemispheric activity with a tonal P300 task after undergoing a fluency-enhancing program.
