Could a magnet on the head ease voice spasms?
NCT ID NCT05095740
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
Laryngeal dystonia causes the vocal folds to spasm, leading to a strained or breathy voice. This study tests whether a non-invasive brain stimulation technique called rTMS can calm the overactive brain signals that cause these spasms. Twenty-five adults with laryngeal dystonia will receive either real or sham rTMS, and researchers will measure changes in voice quality and brain activity. The goal is to see if this approach could offer a new, less invasive alternative to Botox injections.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
repetitive transcranial magnetic stimulation (rTMS)
What this could lead to
If it works, this could point toward a non-invasive treatment option for laryngeal dystonia that reduces voice symptoms without the need for repeated Botox injections.
What could go wrong
This is a very early, small proof-of-concept study with only 25 participants. It tests a single session of rTMS, so any benefits may be short-lived or not work for everyone.
