Two methods of relaxing laryngeal musculature were investigated in adults with hyperfunctional dysphonia. Assessments were conducted pre‐treatment, post‐treatment and at three month follow‐up. Measures included the level of superficial laryngeal tension using an electromyogram, control of vocal fold vibration using Fx traces from an electrolaryngograph and an auditory evaluation using a phonation profile. Two personality questionnaires were administered and the subjects' self‐rating of voice was recorded. The duration of treatment was noted. Subjects were matched into groups receiving either laryngeal EMG biofeedback or progressive relaxation, both within a graded voice training programme. A significant improvement in all measures occurred for both programmes, which was maintained at follow‐up. No significant difference between the two approaches emerged. Implications for the assessment and treatment of hyperfunctional dysphonia are discussed.
