Clinical Trial Summary

The project is leading to investigate the effects of neuromodulation techniques on speech fluency among adults who stutter (AWS). While stuttering is responsive to a variety of treatments in childhood, this is not the case for AWS. Behavioural treatments to reduce stuttering for adults typically consist of speech restructuring methods, which involves the person using one of the altered speech patterns known to increase fluency, such as chorus reading, speaking in rhythm, and prolonging (smoothing/stretching out) speech sounds. Research has shown that behavioural interventions such as these change brain activation patterns in the regions associated with stuttering. Unfortunately, around 70% of AWS who receive these speech restructuring treatments do not maintain the benefits in the longer term and frequently re-present to speech clinics. The aim of this proposed research is to explore whether the brain stimulation using repetitive transcranial magnetic stimulation (rTMS) can consistently enhance effects of behavioural stuttering therapy by examining their responsiveness to the treatment across different outcome measures including a) immediate effect on different speaking contexts, and b) the maintenance of effects over one week after therapy.
