Interventions

This is a randomized (order of completion of the stages) controlled, double-blind, crossover clinical study. There will be six intervention groups, in which all participants will go through all of the

Stage 2: Application of placebo Transcutaneous Electrical Nerve Stimulation (TENS) for 20 minutes, with the equipment turned off

Stage 3: Application of high-frequency Transcutaneous Electrical Nerve Stimulation (TENS) for 20 minutes concurrently with vocal exercises

Stage 4: Application of placebo Transcutaneous Electrical Nerve Stimulation (TENS) for 20 minutes with the equipment turned off, concurrently with vocal exercises

Step 5: 20 minutes of vocal exercises followed by another 20 minutes of high-frequency Transcutaneous Electrical Nerve Stimulation (TENS)

Step 6: Application of high-frequency Transcutaneous Electrical Nerve Stimulation (TENS) for 20 minutes followed by another 20 minutes of vocal exercises. Each intervention step will have a minimum in

Eligibility

Sex/Gender

Female

Age

18 Years to 45 Years

Inclusion criteria

Inclusion criteria: Women aged 18 to 45 years old with current voice complaints and alterations will be included. Participants will answer a Voice Disorder Screening Index (VDI) questionnaire and the Dysphonia Screening Instrument (DSI-Br). Only women who obtain a score of five or higher on the VDI and answer "Yes" to both questions on the DSI-Br will be included in the study. In addition, only those with altered voice evidenced by a pre-assessment of speech-language pathology and a diagnosis of: bilateral nodules or mucosal thickening or cyst with contralateral reaction, glottal gap during phonation, evidenced by otolaryngological evaluation, will be included

Exclusion criteria

Exclusion criteria: Women who have thyroid gland disorders or hormonal imbalances; heart or vascular problems; have colds, allergies, or other upper respiratory tract problems on the day of the speech therapy intervention; those who have previously participated in voice research or treatment where Transcutaneous Electrical Nerve Stimulation (TENS) was applied; have undergone head and neck surgery; are over 45 years of age, in order to isolate variables such as changes resulting from the natural aging process or age-related muscle changes; and are in menopause

Design outcomes

Primary

Measure	Time frame
An improvement in the immediate effects of different forms of application of high-frequency TENS electrotherapy combined with vocal exercises is expected in the self-perception and vocal quality of women with behavioral dysphonia	—

Secondary

Measure	Time frame
An improvement is expected in the immediate effect of different forms of high-frequency TENS electrotherapy intervention on vocal self-assessment; on the perceptual-auditory judgment of vocal quality; on the acoustic parameters of the voice; and on the effects of high-frequency Transcutaneous Electrical Nerve Stimulation (TENS) electrotherapy and vocal exercises	—
