Details and patient eligibility

About

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.

Full description

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.

20 participants in 2 patient groups

adapted Lee Silverman Method
Active Comparator group
Description:
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.
Treatment:
Procedure: Adapted Lee Silverman Method
Lung volume recruitment Technique - LVRT
Experimental group
Description:
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.
