La dislessia evolutiva (DE) è associata ad un deficit di elaborazione temporale degli stimoli uditivi, secondario ad un'attività oscillatoria neurale atipica, che si ritiene contribuisca alle difficoltà fonologiche e di lettura. Per favorire un entrainment più accurato alle proprietà spettro-acustiche degli stimoli uditivi negli studenti con DE, abbiamo esplorato la possibilità di sincronizzare la prosodia durante la lettura con una stimolazione ritmica uditiva. Pertanto, è stato realizzato un programma di intervento per la DE, chiamato Training Lettura Ritmica (TLR). Tre studi test-training-retest hanno mostrato l'efficacia di questa nuova metodologia nel miglioramento delle capacità di lettura in individui italiani con DE, sia in età evolutiva che adulti. Lo studio 1 ha mostrato che il TLR ha portato a miglioramenti della lettura in studenti di scuola primaria e secondaria di primo grado con DE paragonabili a quelli di un intervento risultante dalla combinazione di due trattamenti già validati per la DE, con un effetto lievemente maggiore sulla rapidità di lettura. Inoltre, la consapevolezza fonologica e la capacità di riproduzione ritmica sono migliorate. Lo studio 2 ha esplorato gli effetti a breve e medio termine del TLR, quando combinato con un allenamento uditivo specifico in bambini e preadolescenti con DE, che sono risultati comparabili a quelli di un intervento multi-componenziale personalizzato. Infine, nello studio 3 il TLR è stato applicato con successo ad una popolazione adulta, ossia studenti universitari con DE, anche quando somministrato in combinazione a neuromodulazione (tDCS), la quale aumenta la plasticità delle aree coinvolte.

Abstract
Developmental dyslexia (DD) is associated with deficiencies in temporal processing of auditory stimuli, depending on atypical oscillatory neural activity, that are considered to contribute to phonological and reading impairments. To induce a more accurate entrainment to the spectral properties of auditory stimuli in students with DD, we explored the possibility to synchronize speech prosody during reading with an external rhythmical auditory stimulation. Accordingly, an intervention program for DD, called Rhythmic Reading Training (RRT), was devised. Three test-training-retest studies supported the efficacy of this novel methodology on reading skills of both young and older populations of Italian individuals with DD. Study 1 showed that RRT yielded reading improvements in primary and junior high-school students with DD comparable to those of an intervention resulting from the combination of two already validated treatments for DD, with a slightly larger effect on reading speed. Moreover, phonological awareness and rhythm reproduction improved along. Study 2 explored RRT short- and medium-term effects when combined with a specific auditory training in children and preadolescents with DD, which were found to be comparable to those of a personalized multi-componential intervention. Finally, in study 3 RRT was successfully applied to an older population, namely undergraduate students with DD, also when in combination with a neuromodulation technique (namely, tDCS) boosting plasticity of the involved networks.File | Dimensione | Formato | |
