Overview

Brief Summary

In 3 patients with spasmodic dysphonia, some effects were observed both subjectively and objectively, but the reproducibility was poor and the duration was short.Other treatments (surgical treatment, botulinum treatment) were covered by insurance during the study period and could not show an advantage over those treatments. Although the effect was subjectively observed in essential voice tremor, no objectively significant improvement was observed. No significant effect was observed in psychogenic aphonia.
