About this trial

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.

Treatments tested in this trial

  • Adapted Lee Silverman Method

    Procedure/Surgery

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

  • Lung volume recruitment technique - LVRT

    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.
