Transcranial Magnetic Stimulation in Laryngeal Dystonia
This randomized clinical trial with a crossover design aims to investigate the effects of neuromodulation through repetitive transcranial magnetic stimulation (rTMS) applied to patients diagnosed with laryngeal dystonia. Participants will undergo three experimental conditions: (1) rTMS alone, (2) rTMS combined with speech-language therapy, and (3) sham rTMS combined with speech-language therapy. The order of the conditions will be randomized. Each phase of the protocol will consist of five consecutive sessions.
Outcomes will include acoustic vocal quality parameters, perceptual-auditory voice assessment, self-ratings of vocal effort, smoothed cepstral peak prominence measures, and global perceived change following the intervention. It is expected that the study will contribute to a better understanding of the effects of the intervention on vocal outcomes, supporting the optimization and standardization of therapeutic protocols for laryngeal dystonia.

Acoustic Voice Parameters Assessed Using VoxMetria® and FonoView® Software
기간: through study completion, an average of 6 months
|
Acoustic voice parameters will be assessed using VoxMetria and FonoView software during sustained vowel phonation and connected speech tasks.
The analysis will include F0 standard deviation (F0 SD), F0 variability, semitone variability, jitter, cepstral peak prominence smoothed (CPPS), voiced time, and unvoiced time.
Each parameter will be analyzed separately and reported as the change from baseline to post-intervention.

Vocal Effort Assessed by the Borg Category Ratio 10 Scale for Vocal Effort
기간: through study completion, an average of 6 months
|
Vocal effort will be assessed using the Borg Category Ratio 10 Scale for Vocal Effort.
Scores range from 0 to 10, where 0 indicates no vocal effort and 10 indicates maximum vocal effort.
Higher scores indicate worse perceived vocal effort.
|
through study completion, an average of 6 months

|
Patient Global Impression of Change Assessed by the Patient Global Impression of Change Scale
기간: through study completion, an average of 6 months
|
Global perceived change will be assessed using the Patient Global Impression of Change Scale.
Scores range from 1 to 7, where 1 = very much worse and 7 = very much improved.
Higher scores indicate greater perceived improvement.

Voice-Related Quality of Life Assessed by the Voice-Related Quality of Life Questionnaire (Brazilian Portuguese Version - QVV)
기간: through study completion, an average of 6 months
|
Voice-related quality of life will be assessed using the Voice-Related Quality of Life (V-RQOL) questionnaire, validated for Brazilian Portuguese (QVV).
Scores range from 0 to 100, with higher scores indicating better voice-related quality of life.
