Eye movement as a simple, cost-effective tool for people who stutter: A case study.
Hilary D-L McDonagh, Patrick Broderick, Kenneth Monaghan
PMID 37782243WHAT IT FOUND
In a young man who stuttered, five weeks of online eye-movement training, daily text messages, and continued use of earlier self-help techniques were followed by lower stuttering severity and better self-rated experience at 24 months.
This describes a single person, not proof the method works.
Key findings
01The participant continued using techniques from a previous self-help programme during the five-week intervention.
02At 24 months, the overall SSI-4 category was reported as improving from moderate to very mild.
03The participant said the technique was useful but hard to remember 24 months after training.

What it does not show
This is a single-person case report, so it cannot show whether the eye movement caused the change or whether the change would happen in other people. The participant was a 21-year-old English-speaking man in Ireland, so it says little about children or other languages. He continued using techniques from a previous self-help programme, and the study had no comparison group, so the contribution of any single component cannot be separated. Some scores improved and then partly regressed across follow-up, so the pattern was not always stable. The paper frames the work as low-level evidence and says a pilot randomised trial is needed to determine causality and generalisability.
The easy way to misread this
Do not read this as evidence that eye movement treats stuttering. The participant also continued using techniques from an earlier self-help programme, and there was no comparison group, so the eye movement alone cannot be credited with the changes.
