Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial in voice professionals with both genders aimed to verify the changes in the vocal range profile and the changes in the glottic and vocal tract configuration for more efficient phonation after applying the adapted Lee Silverman Method and the addiction of lung volume recruitment technique in acoustic and structural analysis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A cross-over randomized trial with two arms-the Lee Silverman Method and the addiction of lung volume recruitment technique (LVRT)-will be conducted with voice professionals to assess the effects of both interventions on the acoustic, perceptive, and visual aspects of voice and their impact on respiratory muscle strength.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

adapted Lee Silverman Method

The individuals will perform the Lee Silverman methods adapted to voice professionals. They will do a 14-day protocol, with three sets of 5 repetitions daily.

Group Type ACTIVE_COMPARATOR

Adapted Lee Silverman Method

Intervention Type PROCEDURE

Exercise protocol with 6 steps that the voice professionals adapted from Lee Silverman Method

Lung volume recruitment Technique - LVRT

In the LVRT intervention, the same exercises as in the adapted LEE Silverman intervention will be performed, however, a bag-mask ventilation system (Lumiar, Brazil) will be attached during the emission with an inflated oro-nasal mask (Lumiar, Brazil) connected to a pressure gauge (Illife device, Brazil) that will monitor the inspiratory pressure level between 30 and 40 cmH2O during phonatory emissions. it will be performed 3 sets with 5 repetitions.

Group Type EXPERIMENTAL

Lung volume recruitment technique - LVRT

Intervention Type DEVICE

The adapted Lee Silverman Method will have a addiction of LVRT technique. Lung inflation begins, reaching an optimal inspiratory peak of 30 cmH2O. From this point, the sound /HA/ begins to be emitted until the most comfortable low sound, where the emission should be maintained for as long as possible, making sure that this time is not less than 12 seconds, trying to emit a high and comfortable vocal intensity. When performing the emissions, the mouth should be kept wide open with the tongue, jaw and neck relaxed, repeating 5 emissions in 3 series. Between series, the participant will be instructed to drink 50 ml of water exactly as in the previous emissions.
