    Presentamos un estudio de caso único sobre la potencial relevancia clínica de un nuevo dispositivo de realimentación auditiva retardada (Forbrain® ) en la tartamudez. Se examinó un adulto con tartamudez mediante un diseno˜ de series temporales de caso único (A-B-A) adecuadamente controlado. En cada uno de 6 días consecutivos se dieron instrucciones al sujeto para leer en voz alta durante las 3 fases del estudio: línea base, test y post-test, mientras llevaba colocado un dispositivo Forbrain® . Durante las fases línea base y post-test, el aparato estaba apagado, mientras que este se conectó durante la fase de test. De esta manera se pudieron analizar los efectos transitorios de Forbrain® . Se obtuvieron 6 parámetros cuantitativos de la calidad de la voz durante la lectura a partir de los registros de esta durante cada una de las fases del experimento. Los datos se analizaron estadísticamente mediante el estadístico d para casos únicos. Se observó un claro efecto de Forbrain® en la calidad de la voz al conectar el dispositivo, según revelaron los contrastes significativos ente la línea base y el test, y el test con el post-test en el parámetro tLTAS de la voz. El presente estudio de caso único sugiere la efectividad de Forbrain® para modificar la voz durante el tartamudeo, y da apoyo a la funcionalidad de este como dispositivo de realimentación auditiva retardada.

    We present a single-case study on the potential clinical relevance of a new altered auditory feedback (AAF) device (Forbrain® ) in stuttering. One adult who stutter was tested in an appropriately-controlled single-case time-series (A-B-A) study. On each of six consecutive working days, the stuttering adult was instructed to read aloud during three different experimental phases: Baseline, Test and Post-test, while wearing a Forbrain® headset. During the Test phase the device was turned on, whereas it was off during Baseline and Post-test phases. This way the transient effects of Forbrain® could be analyzed. Six quantitative measures of voice quality were retrieved from the participant’s voice recordings during his readings over each phase of the experiment. Data was statistically analyzed through the single-case d-statistic. A clear transient effect of Forbrain® , when turned on, was observed on voice quality, supported by significant differences between Baseline and Test, and Test and Post-test in the tilt of the trendline of the long term average spectrum (tLTAS) of the voice. The present single-case study support the effectiveness of Forbrain® in modifying the voice during stuttering, supporting its role as an AAF device.
