An interventional study of Resonance Tube Voice Therapy in Water in Functional Dysphonia, Resonance Tube Voice Therapy and Smith Accent Method Therapy, sponsored by Sohag University. Recruiting at 1 site in Egypt. Open to participants aged 15 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-03-04.
Sponsored by Sohag University · Not applicable, Interventional, and Treatment
The purpose of this study is to determine the effect of a semi-occluded vocal tract training program, "Resonant Tube Therapy," versus the "Traditional Smith-accent Method" on the quality of voice in patients with Non-Organic "Functional" dysphonia.
132 studies on the registry are indexed under Dysphonia; 38 are open to participants now.
This study's planned enrollment of 60 is above the median of 30 across 87 interventional studies indexed under Dysphonia.

Exclusion Criteria:
The patient was advised to vocal hygiene and to correct the faulty vocal technique by a-diaphragmatic breathing in the sitting position by Using the newly acquired diaphragmatic breathing, the patient is allowed to "sing" the various vowels (/a/, /i/, and /u/), "the largo with one accentuation, the andante with three accentuations, and the fastest, allegro, with five accentuations". b-Body and arm movements during dynamic vowel exercises. Transfer and carry over to connected speech by (the gradual stage-wise transformation from vowel play to connected speech, repeating short phrases after the therapist, reading short phrases with pauses, monologue with short phrases with suitable pauses, dialogue, applying the same pattern)
The patient sits comfortably with their back straight, holding the tube between their thumb and index fingers, maintaining 1 mm between their teeth, and ensuring no air leak between their lips and the tube. A 1-liter wide plastic container is used, filled with water, with the free end of the tube submerged 2 cm below the water's surface. The patient is instructed to take enough time to relax their respiratory muscles and phonate into the tube to create air bubbles on the water's surface, starting with monotonous words and progressing to different intonations. There are 2-minute rest periods between exercises, and the patient should drink water to prevent dryness. Sessions occur in the clinic until the patient can perform the exercises independently without effort, after which the pathologist may allow practice at home. The patient receives written instructions to practice 10 times daily for 2 minutes each, with 1 hour between practices for 6 weeks.
