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