Item Técnicas de evaluación e intervención en Logopedia: base de datos audiovisual de la Unidad Clínica de Logopedia.(2015) Nieva Ramos, Silvia; Bartuilli Pérez, Mónica; González Calero, Pedro Antonio; Melle Hernández, Natalia; Murillo Sanz, Eva; Pareja Lora, Antonio; Sáenz Pérez, Fernando; Schüller Moreno, Maria TeresaEl proyecto consiste en creación y virtualización de una base de datos audiovisual estructurada de sesiones de evaluación e intervención llevadas a cabo con pacientes que acuden a tratamiento a la Clínica de Logopedia de la UCM con objetivos docentes y de investigación, dando acceso a los alumnos al visionado de vídeos para realizar sesiones de análisis y estudio de casos clínicos a partir de los procesos de evaluación e intervención para las distintas patologías que son su ámbito de estudio. Item Anticipatory coarticulation of the Spanish alveolar fricative /s/ in adults with apraxia versus dysarthria(Revista de Investigación en Logopedia, 2024) Melle Hernández, Natalia; Lahoz Bengoechea, José María; Gallego López, Carlos; Nieva Ramos, SilviaThis acoustic study compares anticipatory coarticulation characteristics of the Spanish alveolar sibilant fricative /s/ when in utterance-initial position followed by a vowel in adults with dysarthria and apraxia of speech. Three groups of participants (28 individuals with no speech disorder, 20 with dysarthria, and 8 with apraxia of speech) produced 12 monosyllabic words that included the five vowel sounds of Central-Peninsular Spanish. The acoustic measurements compared within and between groups were frequency of the spectral intensity peak (FreqMid) in different zones of fricative execution, magnitude of the change in frequency of the spectral intensity peak (ΔFreq) in the end zone compared to the average of the initial and middle zones, first three spectral moments, and the difference in spectral center of gravity between the middle and end zones (DiffM-E CoG). Several of these measures were able to differentiate between dysarthric and healthy speech, especially when /s/ was followed by an unrounded vowel, and the same occurred for apraxia, but this time when the adjacent vowel was rounded. While both disorders showed similar spectral patterns, the two motor speech disorders differed in terms of the measures FreqMid and DiffM-E CoG. Possible explanations for these differences are here discussed within the framework of motor control models.- Project number: 65
Item Coordinación interuniversitaria para la realización virtual de prácticas sanitarias a través de videoconferencias(2021) Lázaro López-Villaseñor, Miguel; Simón López, Teresa; Nieva Ramos, Silvia; Bartuilli Pérez, Mónica; Pérez Naranjo, Narcisa; Schüller Moreno, Maria Teresa; Melle Hernández, Natalia; Terradillos Azpiroz, María Estíbaliz; Pisón del Real, Guzmán; Castejón Fernández, Luis Andrés; Martínez López, María Verónica; Aparici Aznar, Melina; Resina Curado, PaulaEl Proyecto de Innovación presente tuvo como objetivo fundamental continuar con la experiencia de la I Jornada Interuniversitaria online de Práctica Logopédica adecuándola al sentido de un proyecto de innovación docente propiamente. Para ello, no se trataba únicamente de ofrecer conferencias a estudiantes con necesidades de formación práctica, sino dotar de una estructura y sentido formativo a los documentos audiovisuales. El objetivo general fue entonces el dotar de estructura tanto a nivel teórico como a nivel aplicado a un banco de vídeos destinados a la formación práctica de estudiantes del Grado de Logopedia. Item Temporal acoustic properties of the sibilant fricative /s/ for the differential diagnosis of dysarthria and apraxia of speech in Spanish speakers(Clinical Linguistics and Phonetics, 2023) Melle Hernández, Natalia; Lahoz Bengoechea, José María; Nieva Ramos, Silvia; Gallego López, CarlosDysarthria and Apraxia of Speech (AoS) are motor speech disorders in which neurological lesions differentially affect motor control, possibly leading to noticeable differences in articulation and consequently sound production. Among the sounds requiring greater motor capacity because of its articulatory complexity is the voiceless alveolar sibilant fricative /s/. The aim of this study was to identify acoustic variables able to distinguish between dysarthria and AoS, and between these disorders and normal speech in Spanish speakers. The production of this fricative was acoustically examined in 28 individuals with motor neurological disorders (20 with dysarthria, 8 with AoS) and in 28 neurologically healthy persons. Participants repeated 12 monosyllabic words containing the fricative plus one of the five Spanish vowels. The variables measured were absolute durations of the fricative, vowel, and fricative+vowel sequence, along with the vowel-to-fricative duration ratio. Findings indicate that duration of the fricative can distinguish between controls and speakers with dysarthria, but not between controls and speakers with AoS. Measures related to vowel duration served to distinguish between speakers with dysarthria and speakers with AoS and between each of them and controls. Further, speakers with dysarthria and those with AoS differed from each other and from controls in terms of articulatory variability; speakers with dysarthria showing most variability. In the latter participants, articulatory variability was higher for unrounded segments, vowels and fricatives, while in speakers with AoS this variability was higher for rounded segments. These observations are discussed within a framework of motor control models.
