“…Given the typical requirement for 'homework' productions of two sets repeated twice daily over the course of treatment, one can see that the dosage of VFE and the specificity for maximum sustained phonation in exercises #1 and #4 can yield improvement in measures of MPT. 41 Treatment effects for efficient glottal closure at low lung volumes in the absence of hyperfunction have been demonstrated at 3 weeks for VFE intervention, which may help to explain the physiological strategies patients have used to improve MPT measures. 42 To summarise, reports suggest that VFE treatment has an effect on measures of MPT by increasing the power of inspiratory muscles and by increasing muscular coordination, strength, and endurance during exhalation than other voice treatment methods.…”

“…Particularly, in exercise #4 (‘power’) the patient is asked to produce up to five different pitches on sustained phonation for as long as possible. Given the typical requirement for ‘homework’ productions of two sets repeated twice daily over the course of treatment, one can see that the dosage of VFE and the specificity for maximum sustained phonation in exercises #1 and #4 can yield improvement in measures of MPT 41 .

Purpose: There is a diversity in treatment approaches for voice therapy in which aerodynamic treatment effects between the approaches are lacking. The evidence of voice treatments on the maximum phonation time (MPT) was quantified using the statistical approach of a network meta-analysis (NMA).Data Sources: Three databases and manual search from inception to November 2021 were evaluated.Study Selection: Studies were considered which were reports of randomised controlled/clinical trials (RCT) evaluating the efficacy of a specific voice therapy treatment using MPT as an outcome measure in adult participants with voice disorders. Studies were excluded if participants had been diagnosed with neurologicalmotor-speech disorders or who were vocally healthy. Furthermore, no medical, pharmacological, or technical instrumental treatments were used.Data Extraction and Synthesis: Preferred Reporting Items for systematic reviews and meta-analyses extension statement guidelines were followed. Two reviewers independently screened citations, extracted data, and assessed risk of bias using PEDro scale. Random effects model was used for meta-analysis.Results: We identified finally 12 RCT studies (treatment groups n = 285, and control group without an intervention n = 62). Eight interventions were evaluated. The only effective intervention with a significant effect was vocal function exercises (VFE)

“…All have demonstrated efficacy with a range of effect sizes demonstrated across a variety of voice outcome measures; however, none have systematically evaluated the effect of each component or 'ingredient' in the treatment provided. Preliminary research investigating individual effects of components of VFE has isolated the therapeutic effects of practise dosage and the use of a semi-occluded vocal tract (nasal sound) [28,29]; however, this research was conducted in controlled experimental conditions with non-voice-disordered volunteers.…”

Background: Although voice therapy is the first line treatment for muscle-tension voice disorders (MTVD), no clinical research has investigated the role of specific active ingredients. This study aimed to evaluate the efficacy of active ingredients in the treatment of MTVD. A retrospective review of a clinical voice database was conducted on 68 MTVD patients who were treated using the optimal phonation task (OPT) and sob voice quality (SVQ), as well as two different processes: task variation and negative practice (NP). Mixed-model analysis was performed on auditory–perceptual and acoustic data from voice recordings at baseline and after each technique. Active ingredients were evaluated using effect sizes. Significant overall treatment effects were observed for the treatment program. Effect sizes ranged from 0.34 (post-NP) to 0.387 (post-SVQ) for overall severity ratings. Effect sizes ranged from 0.237 (post-SVQ) to 0.445 (post-NP) for a smoothed cepstral peak prominence measure. The treatment effects did not depend upon the MTVD type (primary or secondary), treating clinicians, nor the number of sessions and days between sessions. Implementation of individual techniques that promote improved voice quality and processes that support learning resulted in improved habitual voice quality. Both voice techniques and processes can be considered as active ingredients in voice therapy.

“…The purpose of this study was to modify a single element of the standard VFE protocol as described by Stemple et al (1994) and Roy et al (2001) and determine its contribution to VFE efficacy. This report is the second study in a series of on-going research designed to determine the effects of specific constituent VFE components (Bane, Angadi, Dressler, Andreatta, & Stemple, 2017). This study investigated the effect of three vocal tract postures that differed by degree of occlusion on achievement of MPT goals in a cohort of adult females with normal voice.…”

Vocal function exercises for normal voice: The effects of varying dosage

Abstract: High dosage VFEs may yield more rapid improvement in MPT, however benefits must be weighed against the risk of increased attrition. Low dosage VFEs insufficiently improved MPT. Further research on dosage is warranted, and should include individuals with disordered voice.
