Brief summary
The goal of this clinical trial is to study how a part of the brain called the supplementary motor area (SMA) is connected to speech and reading fluency in adults who stutter. Researchers will use a method called repetitive transcranial magnetic stimulation (rTMS) to learn more about this relationship. The main question it aims to answer is: -Will participants' speech and reading fluency improve when we stimulate the SMA with rTMS? Participants will take part in both placebo rTMS and real rTMS sessions. Participants will: * Come to the research center for 2 days, with at least a one-week break between visits * Read 4 passages and speak on 4 topics * Be video recorded while doing these tasks
Interventions
OTHERBrain stimulation
Participants will be included in the real and sham rTMS. Participants will perform speech and reading tasks before and after stimulation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Severity of stuttering in speech and reading Day 1 (pre-treatment) | Immediately before the treatment (Day 1) | Stuttering severity will be calculated on video recordings taken during speaking and reading tasks. Stuttering Severity Instrument - 4th Edition (SSI-4) scale will be used for this. |
| Severity of stuttering in speech and reading Day 1 (post-treatment) | Immediately after the treatment (Day 1) | Stuttering severity will be calculated on video recordings taken during speaking and reading tasks. Stuttering Severity Instrument - 4th Edition (SSI-4) scale will be used for this. |
| Severity of stuttering in speech and reading Day 2 (pre-treatment) | Immediately before the treatment (Day 2) | Stuttering severity will be calculated on video recordings taken during speaking and reading tasks. Stuttering Severity Instrument - 4th Edition (SSI-4) scale will be used for this. |
| Severity of stuttering in speech and reading Day 2 (post-treatment) | Immediately after the treatment (Day 2) | Stuttering severity will be calculated on video recordings taken during speaking and reading tasks. Stuttering Severity Instrument - 4th Edition (SSI-4) scale will be used for this. |
