Using Transcranial Magnetic Stimulation to Treat Stuttering

Recruiting now · Not applicable

Conditions studied: Stuttering, Adult

In brief

The goal of this clinical trial is to learn if repeated transcranial magnetic stimuli (rTMS) can treat stuttering in adults. The main questions it aims to answer are: * Will there be changes in the brains of people who stutter because of the treatment? * Will any changes in the brain result in less stuttering? Participants will: * Visit the lab 3 times before treatment for tests * Complete 10 rTMS sessions * Visit the lab 2 times after treatment for tests
