IRCT20170922036319N2 IRCT 2018-09-04 Tehran University of Medical Sciences The effect of voice therapy in improving voice quality in teachers Comparative study on the efficacy of symptomatic relaxation techniques, laryngeal manual therapy and combined method in voice therapy in teachers with muscle tension dysphonia 2018-09-05 anticipated 24 Complete https://irct.ir/trial/27187 interventional Randomization: N/A, Blinding: Not blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment. N/A Muscle tension dysphonia. Intervention 1: Intervention group: symptomatic voice therapy :One of the direct approaches is symptomatic voice therapy which proposed by Boone (1971) is based on the principles of behavior therapy. This approach uses a variety of voice facilitating techniques through direct modification respiratory and phonatory systems lead to improvement in symptoms of voice production on correction of voice production symptoms and manipulates voice characteristic. The treatment techniques were presented for 10 individual sessions twice a week and each session lasted approximately 45 min. Intervention 2: Intervention group: manual therapy: Physiologic voice therapy approach is another direct philosophy which recently has been considered in voice therapy of MTD aimed to directly alter or modify the physiology of the vocal mechanism. It seems laryngeal muscle tension imbalance is one possible physiologic cause of voice disturbances so laryngeal manual therapy can be noticed as a useful primary intervention in dysphonia, particularly MTD. In functional voice disorders muscle imbalance pressure, abnormal coordination patterns of muscles and intrinsic and extrinsic laryngeal muscles tension may change the cartilaginous structures and position of the larynx. Circumlaryngeal manual therapy proposed by Aronson is the first laryngeal manual therapy technique which has been gained more attention.The treatment techniques were presented for 10 individual sessions twice a week and each session lasted approximately 45 min. Intervention 3: Intervention group: combined method: Combined approaches combine one or more therapies to treat patients with voice impairment. The treatment techniques were presented for 10 individual sessions twice a week and each session lasted approximately 45 min.
