Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Voice self-assessment. Timepoint: In the initial assessments, the first and second intermediate assessments and the final assessment. Method of measurement: Each patient's perceptual judgment about their own voice quality is made using a Visual Comparative Scale (VAS) through interviews. In other words, in the present study, a 100 mm line is used to measure sound self-assessment, in which a score of 0 means natural sound quality and a score of 100 means the worst sound quality.;Frequency and severity of vocal tract discomfort. Timepoint: In the initial assessments, the first and second intermediate assessments and the final assessment. Method of measurement: To evaluate the frequency and severity of the discomfort experienced in the vocal tract from the participants' point of view, the Persian version of the VTD scale called VTDp will be used. This scale is a self-perceptual questionnaire that will be provided to patients to comment on the frequency and severity of symptoms in the auditory canal.;Pain, tightness, tenderness, hypertrophy, a trigger point in each of the target muscles, the height of the larynx in the neck, limitation in lateral movement of the larynx, and the size of the thyrohyoid and cricothyroid space. Timepoint: In the initial assessments, the first and second intermediate assessments and the final assessment. Method of measurement: In this study, palpation included examination of pain in the target muscles, tightness in each of the target muscles, sensitivity to palpation in each of the target muscles, hypertrophy in each of the target muscles, trigger points in each of the target muscles, laryngeal height, lateral movement limitation of the larynx is the size of the thyroid space and the size of the cricothyroid space. The evaluation method for each of the above is as follows: palpation is done using the index or middle fingers and the thumbs of both left and right hands while the patient is sitting on a chair and the evaluator is standing behi | — |
Secondary
| Measure | Time frame |
|---|---|
| Overall severity of dysphonia and Strain. Timepoint: Once in the initial assessments and the second time in the final assessments. Method of measurement: To assess the Auditory-perceptual voice assessment, two evaluators will listen to the recorded voice samples. Then, for the index of Overall severity of dysphonia and Strain from the Persian version of Consensus Auditory-perceptual assessment -voice profile (ATSHA), they will record a number between 0 and 100. According to, the (ATSHA) instructions, examples of recorded voice include /a/ and /i/ vowel prolong tasks, sentence reading, and continuous speech.;Voice acoustic features involves the extraction of numerical value Jitter, Shimmer, Harmony to noise ratio, and First, second and third formants. Timepoint: Initial and final evaluations. Method of measurement: Acoustic measurement and analysis of patient voice characteristics is performed using praat software. For this purpose, the person's voice when saying vowels and continuous speech is recorded and analyzed using the mentioned software.;Anteroposterior supraglottic constriction, mediolateral supraglottic constriction, and glottal closure. Timepoint: Initial and final evaluations. Method of measurement: The laryngeal examination is performed by observation and using video laryngoscopy technique by an Ear, Nose, and Throat specialist and Speech and Language Pathologist. After examination and review of video laryngoscopic films, the results related to the supraglottic anterior-posterior compression, supraglottic medial-lateral compression, and the model of the glottal closure were extracted and recorded in the relevant form.;Voice acoustic features involves the extraction of numerical value Jitter, Shimmer, Harmony to noise ratio, and First, second and third formants. Timepoint: Initial and final evaluations. Method of measurement: Acoustic measurement and analysis of patient voice characteristics is performed using praat software.
