Abstract

RESUMEN Objetivo: Validar el análisis biomecánico como herramienta de cribado de la disfonía y diseñar un protocolo que establezca la necesidad de derivación a atención especializada. Material y Métodos: Se evaluó a 102 voluntarios, clasificados en grupo control o grupo con patología vocal. Se realizó cribado de voz mediante análisis biomecánico con la herramienta App Online Lab® de Voice Clinical Systems®. Resultados: La edad media fue de 39,8 años. Del total de participantes, 35 se clasificaron en grupo control y 67 presentaban patología vocal. El análisis biomecánico detectó como libres de patología a todos los voluntarios del grupo control (E:1), y como patológicos a 58 de los 67 del grupo con patología vocal (S:0,87). Conclusiones: El análisis biomecánico R1 con umbral del 50% es una herramienta con alta sensibilidad y especificidad para el cribado de la patología de voz y ofrece una nueva posibilidad para su detección y seguimiento.

ABSTRACT Objetive: To validate the biomechanical analysis as a screening tool for dysphonia and to design a protocol that establishes the need for referral to specialized care. Material and Methods: We evaluated 102 volunteers, classified as control group or as subjects with voice pathology. Voice screening test was performed by biomechanical analysis tool App Online Lab® by Voice Clinical Systems®. Results: The mean age was 39.8 years old. Of the total of participants, 35 were classified as control group and 67 presented voice pathology. The biomechanical analysis detected all the volunteers in the control group as free of pathology (specificity of 1), and 58 of 67 in the group with voice pathology as pathological (sensitivity of 0.87). Conclusions: The R1 biomechanical analysis with a 50% threshold is a tool with high sensitivity and specificity for the screening of voice pathology and offers a new possibility for its detection and monitoring.

Voice disorders in the general population: prevalence, risk factors, and occupational impact.

Nelson Roy, Ray M Merrill, Steven D Gray … (2005)

Epidemiologic studies of the prevalence and risk factors of voice disorders in the general adult population are rare. The purpose of this investigation was to 1) determine the prevalence of voice disorders, 2) identify variables associated with increased risk of voice disorders, and 3) establish the functional impact of voice disorders on the general population. Cross-sectional telephone survey. A random sample (n = 1,326) of adults in Iowa and Utah was interviewed using a questionnaire that addressed three areas related to voice disorders: prevalence, potential risk factors, and occupational consequences/effects. The lifetime prevalence of a voice disorder was 29.9%, with 6.6% of participants reporting a current voice disorder. Stepwise logistic regression identified specific factors that uniquely contributed to increased odds of reporting a chronic voice disorder including sex (women), age (40-59 years), voice use patterns and demands, esophageal reflux, chemical exposures, and frequent cold/sinus infections. However, tobacco or alcohol use did not independently increase the odds of reporting of a chronic voice disorder. Voice disorders adversely impacted job performance and attendance, with 4.3% of participants indicating that their voice had limited or rendered them unable to do certain tasks in their current job. Furthermore, 7.2% of employed respondents reported that they were absent from work 1 or more days in the past year because of their voice, and 2% reported more than 4 days of voice-related absence. The results of this large epidemiologic study provide valuable information regarding the prevalence of voice disorders, factors that contribute to voice disorder vulnerability, and the functional impact of voice problems on the general population.

Treatment efficacy: voice disorders.

K Verdolini, L Ramig (1998)

This article reviews the literature on the efficacy of treatment for voice disorders primarily using studies published in peer-reviewed journals. Voice disorders are defined, their frequency of occurrence across the life span is reported, and their impact on the lives of individuals with voice disorders is documented. The goal of voice treatment is to maximize vocal effectiveness given the existing disorder and to reduce the handicapping effect of the voice problem. Voice treatment may be (a) the preferred treatment to resolve the voice disorder when medical (surgical or pharmacological) treatments are not indicated; (b) the initial treatment in cases where medical treatment appears indicated; it may obviate the need for medical treatment; (c) completed before and after surgical treatment to maximize long-term post-surgical voice; and (d) a preventative treatment to preserve vocal health. Experimental and clinical data are reviewed that support these roles applied to various disorder types: (a) vocal misuse, hyperfunction and muscular imbalance (frequently resulting in edema, vocal nodules, polyps or contact ulcers); (b) medical or physical conditions (e.g., laryngeal nerve trauma, Parkinson disease); and (c) psychogenic disorders (e.g., conversion reactions, personality disorders). Directions for future research are suggested which maximize clinical outcomes and scientific rigor to enhance knowledge on the efficacy of voice treatment.
