Aerodynamic Measures in Muscle Tension Dysphonia

In the recent article from Belsky et al, 1 which evaluates aerodynamic and acoustic measurements in healthy patients and patients with primary muscle tension dysphonia (MTD), the authors concluded that connected speech from patients diagnosed with MTD essentially reflect normal acoustic and aerodynamic values.

We greatly appreciated the authors for their work and for their effort in including aerodynamic studies in the assessment of MTD, which we think is important for the understanding of this voice disorder. However, we think that several major issues need to be clarified.
