Abstract
CARDOSO, Isabel et al. Sensitivity of biomechanical analysis as a new tool for the screening of dysphonia. Rev Asoc Esp Espec Med Trab [online]. 2021, vol.30, n.1, pp.81-89. Epub May 10, 2021. ISSN 3020-1160.
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.
Keywords : Biomechanical analysis; dysphonia; voice pathology; screening.
