“…Their diagnosis still presents numerous challenges to both clinicians and researchers [1][2][3]. Occupational dysphonia is complex in nature and requires multidimensional management [4][5][6]. Given that voice is a key tool for professional voice users, its disorders may result in significant communication handicap for those affected [1,7].…”

“…We hypothesized that a useful tool for measuring voice use and voice rest would demonstrate convergent validity (i.e., an association between self‐reported voice use and measured phonation in normal subjects). We expected a moderate strength of association based on other studies of relationships between subjective and objective ambulatory measures . We also hypothesized that such a tool would demonstrate significantly decreased voice use (phonation percent) and loudness (sound level) in patients on voice rest after treatment.…”

Objective Voice rest is frequently recommended following surgical disruption of vocal fold epithelium, but patients report variable adherence to voice rest recommendations. The objective of this study was to assess the clinical utility of an ambulatory vocal dosimeter for measuring adherence to voice rest recommendations. Study Design Outcomes research Methods Part 1: To determine the utility of the dosimeter in non-clinical use, the relationship between self-reported voice use and dosimeter measurements was examined in normal subjects (n=11) who prospectively logged voice use while wearing the dosimeter. Part 2: To determine clinical utility of the dosimeter, patients undergoing vocal fold surgery for which post-operative voice rest was recommended (n=11) wore a dosimeter for two days prior to and two days after surgery. Phonation percent and sound level were compared at baseline and during voice rest. Results The dosimeter performed as hypothesized with both normal subjects and patients. A moderate correlation (r=0.62) was noted between self-reported voice use and dosimeter measurements in normal subjects. In patients on voice rest, a statistically and clinically significant decrease was observed in measured voice use, both in phonation time (p=0.002) and intensity of phonation (p=0.004). Conclusions Ambulatory vocal dosimetry may have clinical utility for assessing adherence to voice rest recommendations. This information will be useful for the design of future studies on voice rest.

“…Central to aerodynamic assessment is the measurement of subglottal pressure (P s ), a parameter valuable in isolation that is also required for determination of vocal efficiency, laryngeal airway resistance (R L ), phonation threshold pressure, and phonation threshold power. Aboras et al measured a wide range of acoustic and aerodynamic parameters and found that P s was the only parameter predictive of patients’ self-perception of dysphonia (6). Routine clinical measurement of P s , therefore, may be valuable.…”

Evaluation of Auditory and Visual Feedback for Airflow Interruption

Introduction Clinical application of mechanical interruption methods for measuring aerodynamic parameters has been hindered by relatively high intrasubject variability. To improve intrasubject reliability, we evaluated the effect of auditory and visual feedback on subject performance when measuring aerodynamic parameters with the airflow interrupter. Methods Eleven subjects performed four sets of ten trials with the airflow interrupter: no feedback (control); auditory feedback (tone matching subject’s F0 played over headphones); visual feedback (real-time feedback of sound pressure level, frequency, and airflow); and combined auditory and visual feedback. Task order was varied across subjects. The effect of each feedback method on mean and coefficient of variation (CV) of subglottal pressure (Ps), mean flow rate (MFR), and laryngeal airway resistance (RL; Ps/MFR) compared to control trials was determined using paired t-tests. Feedback methods were compared against each other using one-way repeated measures analysis of variance. Results Each feedback method significantly decreased the CV of RL compared to control trials (auditory: p=0.005; visual: p=0.008; combined: p<0.001). Auditory (p=0.011) and combined feedback (p=0.026) also decreased the CV of MFR. Mean MFR was significantly higher during trials with visual feedback compared to auditory feedback. Conclusions Each feedback method improved intrasubject consistency when measuring RL. Feedback appeared to have a greater effect on MFR than Ps. While there is no clear optimal feedback method, each is preferable to not providing any feedback during trials. Evaluating new methods of visual feedback to further improve MFR and thus RL measurement would be valuable.

The relationship between subjective self-rating and objective voice assessment measures

Abstract: This cross-sectional study highlights that patients' self-perception of a voice problem is related to their difficulty in sustaining controlled loudness and adequate glottic closure rather than in controlling frequency irregularity.
