Design outcomes
Primary
| Measure | Time frame |
|---|---|
| We expect to find an improvement in voice quality measured through Auditory Perceptual Judgment, verifying the reduction in the values ??of the auditory perceptual analysis carried out by the judges and from this we will observe whether photobiomodulation will contribute to the verification of this parameter | — |
Secondary
| Measure | Time frame |
|---|---|
| We expect to find a reduction in self-perception of vocal effort assessed using the BORG CR10BR scale verifying a reduction in scores and from this we will observe whether photobiomodulation is effective in alleviating the symptom of vocal effort;It is expected to find an improvement in the acoustic indices evaluated through acoustic analysis, which will verify whether the values ??found are compatible with unaltered voices and from this we will observe whether photobiomodulation normalizes or improves the acoustic indices analyzed. | — |
