The Towne-Heuer reading passage—A reliable aid to the evaluation of voice

The science of voice evaluation and assessment has profited from technological advancement and objective measurement of voice parameters has become an integral part of the voice examination, however, subjective voice evaluation remains a vital component of any voice examination. The Towne-Heuer Reading Passage was developed in 1970 to provide a reading sample that would facilitate subjective voice evaluation. The reliability of the passage was established using three judges listening to 15 normal Philadelphia speakers and 15 vocal abuse-misuse clients with verified vocal nodules. The frequency of hard glottal attack (HGA) was determined for the two groups and high interjudge and intrajudge correlation was found. A difference in the frequency of HGA was found between the two groups.     

Outcome of laryngeal manual therapy in four Dutch adults with persistent moderate-to-severe vocal hyperfunction: a pilot study

A relatively new management strategy for the treatment of voice disorders is the use of laryngeal manual therapy. The main purpose of the present pilot study is to document the outcome of vocal quality after a well-defined laryngeal manual therapy (LMT) program. Four Dutch professional voice users with a persistent moderate or severe muscle tension dysphonia were studied pretreatment (1 week before LMT) and posttreatment (1 week) after completion of manual therapy (25 sessions). These subjects had received several months of traditional voice therapy, without any success. To measure and compare, the effect of LMT objective and subjective assessment techniques were used. Perceptual voice assessment included a perceptual rating of the voice using the GRBAS scale. Furthermore, the vocal quality in this population was modeled by means of the Dysphonia Severity Index (DSI). All of the subjects selected for LMT showed improvement in perceptual vocal quality and DSI values. As the DSI is a weighted variable including aerodynamic and acoustic measures, small improvements (closer to 5) are very indicative of vocal quality improvement.¹ The use of LMT in professional voice users with persistent moderate-to-severe muscle tension dysphonia, especially in some subjects who have not responded to traditional voice therapy, is supported by this pilot study.     

The Frequency of Perceived Stress, Anxiety, and Depression in Patients with Common Pathologies Affecting Voice

The study's objectives were to investigate (1) the frequency of perceived stress, anxiety, and depression for patients with common voice disorders, (2) the distribution of these variables by diagnosis, and (3) the distribution of the variables by gender. Retrospective data were derived from self-report questionnaires assessing recent stress (Perceived Stress Scale-10), anxiety, and depression (Hospital Anxiety and Depression Scale) in a cohort of new patients presenting to a voice clinic. Data are presented on 160 patients with muscle tension dysphonia (MTD), benign vocal fold lesions, paradoxical vocal fold movement disorder (PVFMD), or glottal insufficiency. Pooled data indicated that average stress, anxiety, and depression scores were similar to those found for the healthy population. However, 25.0%, 36.9%, and 31.2% of patients showed elevated stress, anxiety, and depression scores, respectively, compared to norms. Patients with PVFMD had the most frequent occurrence-and patients with glottal insufficiency had the least frequent occurrence of elevated stress, anxiety, and depression. Stress and depression were more common with MTD than with lesions, whereas reverse results were obtained for anxiety. More females than males had elevated stress, anxiety, and depression scores. The data are consistent with suggestions that stress, anxiety, and depression may be common among some patients with PVFMD, MTD, and vocal fold lesions and more common for women than men. However, individual variability in the data set was large. Further studies should evaluate the specific role of these conditions for selected categories of voice disorders in susceptible individuals.
