Diagnostic criteria in functional dysphonia

Abstract

One thousand consecutive patients seen in a multidisciplinary voice clinic are reviewed. The incidence and relative severity of diagnostic features in each of five assessment areas are calculated and compared. The five areas include: 1. history, 2. laryngoscopic examination, 3. perceptual-acoustic assessment, 4. voice related musculoskeletal, and 5. psychological evaluations. Feature prevalence is presented for patients we have classified as having muscular tension dysphonia, which can be primary, or associated with vocal nodules, chronic laryngitis, or polypoidal degeneration; or as having a psychogenic "functional" dysphonia. Following review of the data, we present a suggested list of diagnostic criteria that should be present before using a specific diagnostic label. These criteria have been further broken down into those that will be present to make a diagnosis, and those that may be present.

A virtual trajectory model predicts differences in vocal fold kinematics in individuals with vocal hyperfunction

“…Estimates of the prevalence of vocal hyperfunction indicate that the condition may account for 10%-40% of cases referred to multidisciplinary voice clinics ͑Roy, 2003͒, yet there is no commonly accepted objective measure for its detection and assessment. Vocal hyperfunction could be due to psychological and/or personality factors, misuse of muscles, learned adaptation following a short-term respiratory illness such as a cold, or compensation for underlying vocal disease ͑Aron-son, 1980; Morrison et al, 1983;Morrison et al, 1986;Rammage et al, 1987;Morrison and Rammage, 1993;Hsiung and Hsiao, 2004͒. However, claims of increased muscle tension are largely based on subjective accounts of the symptom complex.…”

“…All participants were female due to the prevalence of vocal nodules in the female population compared to the male population ͑Morrison et Morrison et al, 1986;Titze, 1989;Pontes et al, 2002͒. No participants with MTD or nodules had a history of any other speech or language disorder.…”

Acoustic analysis assessment in speech pathology detection

“…Functional dysphonia occurs predominantly in women, commonly follows upper respiratory infection symptoms, can be transient and varies in its response to treatment (Morrison et al, 1986;Roy, 2003). FD is often regarded as a disorder on a continuum of severity and it implies 1 www.stimmdatenbank.coli.uni-saarland.de.…”

Comparison of voice relative fundamental frequency estimates derived from an accelerometer signal and low-pass filtered and unprocessed microphone signals

“…Current clinical assessment of VH primarily depends on clinicians' subjective interpretations based on auditory and visual perception, patient history, palpation of neck musculature, and patient report of selfperceived fatigue or discomfort (Morrison et al, 1986;Roy et al, 1996;Behrman, 2005). RFF is a promising measure for objective assessment of VH.…”
