Validación del análisis biomecánico para el cribado de patología de la voz

Abstract

Background and Objetive; Voice pathology reaches a prevalence in theWestern world of up to 15%. The most common classification is divided into organic andfunctional dysphonia. The early detection of the disease prevents its progression towardsconsolidated lesions that are difficult to manage. For this reason, it is highlyrecommended to have tools that allow their detection. The objective of this study is tovalidate biomechanical analysis as a screening tool for voice pathology. Material andMethods: We evaluated 131 volunteers– 34 subjects without pathology; 36 with adiagnosis of functional dysphonia and 61 with a diagnosis of organic dysphonia -. Afterdiagnosis by videolaryngoscopy and VHI-10 test, R1 voice screening test was carried outby biomechanical analysis tool App Online Lab® by Voice Clinical Systems®. Results:Screening by biomechanical analysis with a 50% alteration threshold presented veryadequate sensitivity and specificity indices in voice pathology screening: Control groupvs. Organic Dysphonia, Specificity: 1, Sensitivity: 0.80; Control group vs. FunctionalDysphonia, Specificity: 1, Sensitivity: 0.67; Functional Dysphonia vs. OrganicDysphonia, Specificity: 0.98; Sensitivity: 0.67; Dysphonia group (Organic Dysphonia +Functional Dysphonia) vs. Non Dysphonia group, Specificity: 1; Sensitivity: 0.81.Conclusions: The R1 biomechanical analysis with a 50% threshold is a tool with highsensitivity and specificity for the screening of voice pathology.
