Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected primary outcome: Self-assessment of vocal symptoms using the index screening protocol for voice disorders - SIVD;Primary outcome found: reduction of vocal symptoms, using the ISVD protocol, after training, regardless of the intervention group (p <0.001) | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected secondary outcome 1: vocal fatigue self-assessment by means of vocal fatigue index -VFI;Secondary outcome found 1: decrease in vocal fatigue symptoms regarding the "vocal fatigue and restriction" (p <0.001) and "physical discomfort" (p <0.001) domains of the IFV protocol, after treatment (post and post1), regardless of intervention group;Expected secondary outcome 2: vocal quality through auditory-perceptual analysis using the GRBASI numerical scale and voice acoustics using the MDVP computer program;Secondary result found 2: the degree of deviation from the hoarseness parameter, using the GRBASI numerical scale, remained the same in the pre- and post-training moments, but lower when compared to the evaluation one month after the training ended (p <0.001). The tension (p = 0.002) and instability (p = 0.033) parameters showed higher values ??for the SG when compared to the CG, regardless of the moment. There is a worsening in the tension parameter at the post, regardless of the intervention group (p = 0.049). There were no changes in the acoustic parameters, using the computerized MDVP software, after the interventions. | — |
