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
Measures must be obtained to in preparation for TMS treatment. Structural MRI and resting-state functional MRI (rsfMRI) recordings will be obtained from the participant, and they will undergo a neuronavigational session to determine best placement for the electrodes. MRI/rsfMRI recordings: The structural MRIs will be obtained and used for TMS neuronavigation. Resting-state functional MRI will be recorded for 8 min with the eyes open. rTMS will be delivered at 10 Hz for 10 min with a stimulation intensity of 120% of the resting motor threshold (rMT). Neuronavigation: The TMS coil will be navi…
Inclusion Criteria: * Age from 18 to 65 years * Self-identifies as a person who currently stutters * Right-handed or left-handed * Normal hearing and (corrected) vision * Able to understand and give informed consent * Monolingual English speaker Exclusion Criteria: * Cardiac pacemaker or pacemaker wires; neurostimulators; implanted pumps * Metal in the body (rods, plates, screws, shrapnel, dentures, IUD) or metallic particles in the eye * Facial tattoos * Not having medical insurance * Surgical clips in the head or previous neurosurgery * Any magnetic particles in the body * Cochlear implan…
This study uses Transcranial Magnetic Stimulation (TMS) applied to specific speech and motor areas of the brain to stimulate cortical areas that experience reduced activations during left-hemisphere dominant tasks in people who stutter.
