Salient Voice Symptoms in Primary Muscle Tension Dysphonia.
Avery Moore, Adrianna C Shembel
PMID 39755526WHAT IT FOUND
Patients with muscle tension dysphonia reported significantly higher vocal effort, fatigue, and discomfort than healthy controls.
Acoustic voice quality and pain did not differ between groups. Standard self-report questionnaires accurately captured these symptoms at the time of evaluation.
Key findings
01Vocal effort, vocal fatigue, and vocal tract discomfort were significantly higher in patients with primary muscle tension dysphonia compared to vocally healthy controls, while odynophonia and perceived vocal quality did not differ.
02Acoustic measures of voice quality showed no significant differences between groups and did not correlate with self-reported voice symptoms.
03Self-reported acute symptoms at the time of evaluation correlated significantly with chronic symptom severity measured by standard indices.

What it does not show
The sample size was too small to determine diagnostic cutoff scores for symptoms. The study only examined acoustic measures and did not evaluate aerodynamic or laryngeal imaging data. The results may not apply to all patients with primary muscle tension dysphonia, as the condition has varying presentations.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not assume that normal acoustic voice quality or the absence of pain rules out primary muscle tension dysphonia. This study found that patients with this condition often report high effort and discomfort despite having voice sounds and pain levels similar to healthy individuals.
