Comparing Face-to-face Group Voice Therapy to Telepractice Group Voice Therapy for Muscle Tension Dysphonia: A Non-inferiority Randomized Controlled Trial
The goal of this clinical trial is to compare face-to-face group voice therapy to telepractice group voice therapy for muscle tension dysphonia (MTD). The main questions it aims to answer are: * The effectiveness of telepractice voice therapy for MTD using a randomized controlled trial study design. * The effectiveness of telepractice group voice therapy using a randomized controlled trial study design. Participants will receive telepractice group voice therapy or face-to-face group voice therapy. Researchers will compare telepractice group voice therapy to face-to-face group voice therapy for patients with MTD to see if it has the same effectiveness.
• Above or equal to 18 years of age;
• Diagnosis of primary MTD or secondary MTD where voice therapy is the primary mode of treatment, such as vocal fold nodules;
• Chinese-speaking subjects only.
