Age
18 Years to 45 Years

Inclusion criteria

Inclusion criteria: complaint of vocal alteration; altered voice evidenced by a speech-language auditory perceptual pre-assessment; bilateral vocal nodules or mucosal thickening or edema and glottic cleft on phonation; not having used TENS for any type of treatment

Exclusion criteria

Exclusion criteria: volunteers who had received speech therapy before; over 45 years of age; who reported being or had completed menstrual flow; who reported any general neurological alterations; thyroid gland changes, who had undergone clinical treatment for hormonal control (except contraceptive pill); vocal or surgical laryngeal treatment; heart problems, high blood pressure, hyper or hypothyroidism; smokers; alcoholics

Design outcomes

Primary

MeasureTime frame
Main outcome: Evaluate by vocal treatment with TENS followed by vocal therapy the vocal quality through perceptual analysis and vocal acoustics;Outcome 1: There was no change in vocal quality through perceptual analysis in both groups after treatment. There was a reduction in the acoustic parameter SPI (mild phonation index) for both groups after 12 treatment sessions and one month after).;Outcome 2: Decreased nodular vocal fold lesion size only for EG immediately after one month of treatment;Outcome found 3: There was no change in voice-related quality of life for both groups. There was improvement in vocal self-perception for both groups immediately and after one month of treatment.;Outcome 4: Reduction of musculoskeletal pain in the proximal regions of the larynx in both groups. The EG showed an increase in the trapezius muscle pain threshold;Expected Outcome 2: To evaluate vocal treatment with TENS followed by vocal therapy for laryngeal aspects by nasolaryngoscopy.;Expected outcomes 3: Evaluate vocal treatment with TENS followed by vocal therapy for voice-related quality of life using the QoL protocol;Expected Outcome 4: To evaluate vocal treatment with TENS followed by vocal therapy for musculoskeletal pain through the Musculoskeletal Pain Investigation protocol, and trapezius muscle pain threshold using the digital algometer;Expected Outcome 5: Muscle activity by surface electromyography of the trapezius, sternocleidomastoid, infra and suprahyoid muscles It has not been analyzed to date
