Brain-Computer Interface Improves Symptoms of Isolated Focal Laryngeal Dystonia: A Single-Blind Study
Movement Disorders2/1/2026·02/01/26🌐 Europe
Summary
Ten patients with laryngeal dystonia underwent a five-day non-invasive closed-loop BCI neurofeedback intervention using real-time EEG during symptomatic speaking. Patients showed statistically significant reductions in voice symptoms paralleled by decreased left frontal delta and central gamma power.
Why it matters
This is the first study demonstrating BCI neurofeedback as a treatment for focal dystonia, opening a new therapeutic avenue for this challenging movement disorder. The non-invasive approach could be extended to other task-specific dystonias.
