About

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.

Enrollment: 60 estimated patients

Sex: All

Ages: 15 to 60 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Patients 'ages between 15 - 60 years old.
• Native speakers of Arabic.
• Language comprehension adequate for the task.

Exclusion criteria

• Patients with organic voice disorders.
• Patients with aphonia or Phon asthenia.
• Females within the week of their menstrual cycle or menstruating at the time of data collection to control for the possible hormonal effects or premenstrual water retention on voice quality.
• History of severe respiratory allergies, thyroid pathologies, neuro-motor impairment, hearing impairment, psychiatric problems and physically limiting diseases that might interfere with study completion.

60 participants in 2 patient groups

Non-organic (Functional) dysphonia patients will receive Smith Accent Voice Therapy

No Intervention group

Description:

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)

Non-organic (Functional) dysphonia patients will receive Resonance Tube Voice Therapy

Active Comparator group

Description:

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.
