Summary

The aim of this study is to determine the effectiveness of concurrent transcranial direct current stimulation (tDCS) and fluency training in adults with developmental stuttering. We examine the severity of stuttering to investigate the effect of treatnment. In the control group the anodal tDCS and DAF will applied on six consecutive days (1 milliampere \[mA\] for 20 mins per day), and the control group will received the sham stimulation and DAF for the same time. The severity of stuttering measured by means of tasks and questionnaires before and after treatment sessions and 6 weeks after intervention.

Conditions

  • Stuttering/ Developmental

Interventions

DEVICE

Anodal tDCS

1 mA anodal tDCS positioned over left superior temporal gyrus and the cathode placed over the occipital lobe. The tDCS stimulation will be delivered for 20 minutes on 6 intervention days.

BEHAVIORAL

fluency intervention/ Delayed Auditory Feedback

Each participant complete three tasks include reading, conversation, and narration. Delayed auditory feedback will be used during these tasks. Each treatment session will take 20 minutes.

DEVICE

Sham tDCS

The anodal tDCS positioned over left superior temporal gyrus and the cathode placed over the occipital lobe. The current of sham stimulation will involve 30 seconds of stimulation at the beginning of the 20 minutes on 6 intervention days.
