简要总结
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.
详细描述
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.

研究组 & 干预措施
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.
干预措施: Adapted Lee Silverman Method (Procedure)
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.
干预措施: Lung volume recruitment technique - LVRT (Device)
