Interventions
Participants will be allocated into three groups, each with 10 participants: G1 - group that will be applied to TENS
G2 - group that will perform TML
G3 - group with association of TENS and TML
, according to randomized numerical list generated by the site "random.org". All participants will be evaluated initially and will serve as the study control group. Each subject will be recruited for

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Improvement of vocal quality, determined by perceptual-auditory evaluation through the GRBASI protocol and acoustical voice analysis, using Voxmetria software. | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to find an increase in the maximum phonation time, measured by the mean in seconds of the maximum phonation times of the vowels / a /, / and /, / i /, / o /, / u / and fricatives / s / z /. reduction of muscular hypertension and decrease of vocal symptoms.;It is expected to find a decrease in the report of muscular pain, measured through the protocol of self-perception based on the Questionnaire of Musculoskeletal Symptoms Nordic-NMSQ. According to the scale used, the regions of the body that will be searched for with regard to pain are: upper back, elbows, wrists / hands / fingers, lower back, hips / thighs, knees, ankles / feet. For this study, the following regions will be included: temporal region, masseter, submandibular, larynx, anterior and posterior region of the neck. The pain intensity will be analyzed by means of an analogue scale with a length of 100 mm, in which the subject should mark a vertical cross at the point where he refers to his level of pain. The left border means no pain, and the right border refers to the worst possible pain. An analogue scale was created for each region investigated.;Reduction of muscle hypertension, measured by the Laryngeal Palpatory Scale protocol, is expected to measure muscular tension level in the extrinsic musculature of the larynx.;It is expected to find a decrease in vocal symptoms, which will be measured by means of the vocal symptoms scale - ESV. | — |
