Abstract

Results from a large study of adults who completed a randomized crossover study of listening and communication enhancement (LACETM) training were analysed to observe trends. The objective of this study was to determine predictors for greatest improvement following this four-week adaptive auditory training and aural rehabilitation program. Subjects with the poorest scores on the baseline tests, particularly those with the greatest degree of hearing loss, poorest scores on measures of degraded and competing speech, and those with the highest hearing handicap scores, were more likely to have greater improvement overall. However, there was considerable variability among the subjects, and some subjects’ positive subjective reports belie smaller overall measured gains. Information collected from both the testing and the counseling of the patient should be taken into consideration when determining whether to proceed with LACE™ training.

Sumario

Se analizaron los resultados de un amplio estudio en adultos que completaron un estudio cruzado de distribución aleatoria de entrenamiento para mejorar la audición y la comunicación (LACE™), para observar las tendencias. Los objetivos de este estudio fueron determinar los elementos de predicción para la máxima mejoría después de este programa de entrenamiento auditivo ajustable y de rehabilitación auditiva de cuatro semanas. Los sujetos con las puntuaciones más bajas en las pruebas basales, particularmente aquellos con los grados de hipoacusia mayores, los de puntuación más baja en mediciones con lenguaje degradado y en competencia, y aquellos con la puntuación más alta de impedimento auditivo, eran los que tenía mayores posibilidades de mejoría global. Sin embargo, existió una considerable variabilidad entre los sujetos, y algunos reportes subjetivos positivos ocultaron ganancias medidas globales más pequeñas. La información colectada tanto de la evaluación como de la orientación del paciente, debe ser tomada en consideración en el momento de determinar cuando proceder con un entrenamiento LACE™.
