Recruiting

• Conditions: Dysphonia

• Registration Number: NCT06124053
• Lead Sponsor: Hacettepe University

Brief Summary

This study aims to investigate whether there is a difference between groups receiving "group voice therapy" and "individual voice therapy" in pediatric populations diagnosed with dysphonia. In this context, the goal is to comprehensively examine the effectiveness of "group voice therapy" in pediatric populations compared to similar studies in the literature. In line with this objective, it is aimed to comprehensively test its effectiveness by including perceptual and acoustic evaluation findings, objective and subjective assessments, and incorporating comparison and control groups into the study, as compared to similar studies in the literature.

Detailed Description

There are three groups in total in the study: two research groups and one control group. The first research group will receive "group voice therapy". Group voice therapy sessions are arranged in groups of three. A total of eight sessions will be given, one session per week. The second research group will receive "individual voice therapy". In this context, participants will be given individual voice therapy for a total of eight sessions, one session per week. The voice therapy approach to be applied to participants receiving individual voice therapy and group voice therapy includes direct and indirect voice therapy methods.Control group participants will receive a one-session "vocal hygiene training".

Control group participants will be evaluated before and after vocal hygiene training. The first and second research groups will be evaluated four times in total: before therapy, after therapy, third month follow-up and sixth month follow-up. It is aimed to examine the effectiveness of "group voice therapy" by comparing the findings obtained from the approaches. Objective and subjective evaluation tools will be used in the evaluations. It is expected that Research Group 1, receiving "group voice therapy," and Research Group 2, receiving "individual voice therapy," will demonstrate a significant decrease in the primary outcome measure, the GRBAS score, and secondary outcome measures, including the Pediatric Voice Handicap Index score, the Teacher's Perception-Based Voice Handicap Index score, and a significant increase in the Pediatric Voice-Related Quality of Life Scale score when comparing pre-therapy and post-therapy assessments. It is anticipated that these significant changes will be sustained in the follow-up evaluations.
