Abstract

Currently, the National Health Service, as well as The Royal College of Speech and Language Therapists, places a great deal of emphasis on treatments which have a strong evidence base. However, although the last two decades have witnessed an increase in research in voice therapy, there is still a lack of efficacy studies in treatments for voice disorders, particularly inorganic disorders such as muscle tension dysphonia. There are two main confounding issues in efficacy research in voice therapy. One is the eclectic use of criteria to measure change which has made it difficult to standardize outcomes the other is the lack of studies using objective means to measure outcomes. This pilot study aims to build on existing studies done on the efficacy of laryngeal manual therapy as a treatment for muscle tension dysphonia, and to pilot more extensive studies in the area. The study focused on immediate changes captured objectively using instrumental equipment: the laryngograph. The laryngograph captures physical changes in the vocal apparatus through measuring acoustic features which are associated with aspects of voice. The voices of ten subjects diagnosed with muscle tension dysphonia were recorded and analysed by the laryngograph immediately before and after a session of laryngeal manual therapy by an expert clinician. Although statistical analysis did not show significant change due to the small size of the group, individual results suggest most subjects experienced change and improvement in acoustic parameters associated with pitch and voice quality.
