“…Because the literature supports self‐perceived metrics as the most reliable indicator of pMTD, 6,29,30 two such indices were used as additional inclusion criteria. The goal of these indices was to ensure significant group differences in self‐perceived severity of vocal impairment using the Voice Handicap Index‐10 (VHI‐10) and severity of vocal fatigue—a common complaint in patients with pMTD, 2,31 using the Vocal Fatigue Index (VFI).…”

ObjectivesIt has been assumed that patients with primary muscle tension dysphonia (pMTD) have more extrinsic laryngeal muscle (ELM) tension, but tools to study this phenomenon lack. Shear wave elastography (SWE) is a potential method to address these shortcomings. The objectives of this study were to apply SWE to the ELMs, compare SWE measures to standard clinical metrics, and determine group differences in pMTD and typical voice users before and after vocal load.MethodsSWE measurements of the ELMs from ultrasound examinations of the anterior neck, supraglottic compression severities from laryngoscopic images, cepstral peak prominences (CPP) from voice recordings, and self‐perceptual ratings of vocal effort and discomfort were obtained in voice users with (N = 30) and without (N = 35) pMTD, before and after a vocal load challenge.ResultsELM tension significantly increased from rest‐to‐voiced conditions in both groups. However, the groups were similar in their ELM stiffness levels at SWE at baseline, during vocalization, and post‐vocal load. Levels of vocal effort and discomfort and supraglottic compression were significantly higher and CPP was significantly lower in the pMTD group. Vocal load had a significant effect on vocal effort and discomfort but not on laryngeal or acoustic patterns.ConclusionSWE can be used to quantify ELM tension with voicing. Although the pMTD group reported significantly higher levels of vocal effort and vocal tract discomfort and, on average, exhibited significantly more severe supraglottic compression and lower CPP values, there were no group differences in levels of ELM tension using SWE.Level of Evidence2 Laryngoscope, 2023

“…Vocal effort is a commonly reported complaint for professional voice users in many sectors including performance, telemarketing/health, and education [4,13,87]. Reported symptoms of increased perceived vocal effort and measurable vocal fatigue include increased instability and breathiness, reduced agility and range, laryngeal discomfort, and increased phonation threshold pressures (PTP) [88][89][90]. The etiology of these symptoms is multifaceted and may arise (for example) from changes in vocal-fold viscosity, fatigue of intralaryngeal musculature and connective tissue, dehydration, or a combination of factors including these [91,92].…”

“…In the EASE-3 these sensations are reported in Q1 (My voice is husky) and Q2 (My voice is dry/scratchy). Breathiness is also part of the symptomology of vocal effort and fatigue [89] and is easily recognized by both singer and listener. Glottal sufficiency and its relation to breathiness is implied in scale item 11 (My top notes are breathy).…”

To date, no established protocol exists for measuring functional voice changes in singers with subclinical singing-voice complaints. Hence, these may go undiagnosed until they progress into greater severity. This exploratory study sought to (1) determine which scale items in the self-perceptual Evaluation of Ability to Sing Easily (EASE) are associated with instrumental voice measures, and (2) construct as proof-of-concept an instrumental index related to singers’ perceptions of their vocal function and health status. Eighteen classical singers were acoustically recorded in a controlled environment singing an /a/ vowel using soft phonation. Aerodynamic data were collected during a softly sung /papapapapapapa/ task with the KayPENTAX Phonatory Aerodynamic System. Using multi and univariate linear regression techniques, CPPS, vibrato jitter, vibrato shimmer, and an efficiency ratio (SPL/PSub) were included in a significant model (p < 0.001) explaining 62.4% of variance in participants’ composite scores of three scale items related to vocal fatigue. The instrumental index showed a significant association (p = 0.001) with the EASE vocal fatigue subscale overall. Findings illustrate that an aeroacoustic instrumental index may be useful for monitoring functional changes in the singing voice as part of a multidimensional diagnostic approach to preventative and rehabilitative voice healthcare for professional singing-voice users.
