Design outcomes

| Measure | Time frame |
|---|---|
| Surface electromyographic evaluation: will be performed with the surface electromyograph model NM800F - New Miotool Face USB (Biotec) and New Miotool software in the bilateral trapezius, bilateral sternocleidomastoid muscles, bilateral and suprahyoid infra-hyoids. ;Laryngeal diagnosis: the medical diagnosis issued by an otorhinolaryngologist based on the images of telelaryngoscopy, nasolaryngoscopy and strobolaryngoscopy will be considered. Evaluation of vocal quality: perceptual-auditory and acoustic analysis based on the vowel / a / sustained emissions and the count of usual pitch and loudness numbers. The perceptual-auditory analysis will be performed by three judges who will analyze the parameters: general degree of vocal deviation, roughness, breathiness and tension. For each parameter evaluated, a visual analogue scale of 100mm will be used. The acoustic analysis will be performed using Sound Forge 10.0® software (Sony Creative Software Inc) and measures will be: fundamental frequency (F0), fundamental frequency variation (vF0), jitter percent, shimmer percent, Amplitude variation (vAm), noise-harmonic ratio (NHR), voice turbulence index (VTI) and soft phonation index (SPI). | — |

| Vocal self-perception: Participants should point out, on a likert scale, the response corresponding to the perception of the voice at that time, "one" representing excellent self-perception, "two" a very good voice, "three" "Four" a reasonable voice and "five" a bad voice. Self-perception of vocal symptoms: To analyze the frequency and intensity of vocal symptoms will be used the 13 symptoms of the protocol Screening Index for Voice Disorders (GUIRARDI et al., 2013). The form of analysis was adapted by the researchers of the present study. Participants will be instructed to note how often each symptom has been present in the last thirty days, on a likert scale of: "never" (zero) to "always" (three). With regard to intensity, they should point out how intense the pain was at that time, on a likert scale, between: "absent" (zero) and "worst possible" or "most intense" (ten). The frequency and intensity of each symptom will be calculated individually. Self-perception of musculoskeletal pain: to investigate the frequency and intensity of musculoskeletal pain, participants will respond to the Musculoskeletal Pain Research Questionnaire (SILVERIO et al., 2014). The proximal and distal regions of the larynx will be investigated, being: anterior and posterior part of the neck, shoulders, upper back, temporal region, masseter, submandibular and larynx. To investigate the frequency of musculoskeletal pain, the participants will be asked to indicate, for each region, one of the response options that varied between "never" and "always". Subsequently, the answers will be placed on a four-point Likert scale, where "never" was equal to zero and "always", referring to three. Then, they will be instructed to indicate the intensity that this pain appeared in each of the above regions, on an individual analogue-visual scale with 100mm, the left border being equivalent to no pain and the right border, equivalent to Worst pain possible. Subsequently, this marking will be measured w | — |
