Results
We found overactivation in the left sensorimotor cortex and the left thalamus in SD patients, suggesting that voice perception activates different neural systems between SD patients and healthy participants. For SD patients, moreover, the magnitude of sensorimotor activation showed a significant positive correlation with symptom severity measured by voice handicap index-10, suggesting that signals from the sensorimotor cortex can be a new biomarker for assessing disease severity.

Baseline Characteristics
Eleven patients with the adductor-type SD and 11 age- and gender-matched healthy participants underwent functional MRI.
Participant flow
Participants underwent functional MRI during a two-alternative
judgment task for auditory stimuli, which could be modal or falsetto voice.
Adverse events
none
Outcome measures
we submitted the three contrast images per participant to a analysis of variance (ANOVA) to examine the efects of stimulus type (modal voice, falsetto voice) and group (SD and control)
on brain activation.
