Abstract

This study aimed to develop a multisensory intervention program for subjects with dyslexia and to analyze the clinical significance of the subjects' performance in two pilot studies. Method: The study was developed in 2 phases, Phase 1 being the elaboration of a multisensory intervention program for subjects with dyslexia based on the studies described in the literature and Phase 2 the application and analysis of the clinical significance of the performance of students with dyslexia in the multisensory intervention program developed. In Phase 1 a bibliographical survey was carried out for the elaboration of the program, elaborated from the alphabet recognition skills, grapheme-phoneme correspondence, knowledge of articulatory point of the phoneme, accomplishment of letter tracing, stereognosia, rhyme identification, rhyme production, identification of alliteration, alliteration production, syllabic addition, syllabic subtraction, syllabic substitution, syllabic combination, phonemic addition, phonemic subtraction, phonemic substitution and phonemic combination. Phase 2 was divided into two pilot studies. Pilot Study I participated in 5 subjects from the 3rd to the 5th year of primary education, aged 8 to 10 years and 11 months, of both genders, with an interdisciplinary diagnosis of dyslexia; and the Pilot Study II had as participants 10 subjects from the 3rd to the 5th year of primary education, aged 8 to 10 years and 11 months, of both genders, with an interdisciplinary diagnosis of dyslexia, divided into 2 groups. Group I (GI): composed of 5 subjects with interdisciplinary diagnosis of dyslexia submitted to the intervention and Group II (GII): composed of 5 subjects with an interdisciplinary diagnosis of dyslexia not submitted to the intervention. All subjects were submitted in the pre- and post-test to the application of the Metalinguistic and Reading Skills Tests and the Spelling Assessment Protocol. Statistical analysis was performed using the JT method to verify whether there was a positive or negative change and clinical significance, thus evidencing the therapeutic efficacy of the program elaborated in Phase 1. Results: Based on the results and the application of the Multisensory Intervention Program in the Pilot Study I, it was necessary to change stimuli in sessions 6 to 10, as well as in the activities of the Domain ability of the Alphabetical Principle. The results of the Pilot Study II showed that there was improvement and clinical significance in the tests of metalinguistic abilities, as identification of initial and medial phoneme; addition, subtraction, substitution and segmentation of syllables; repetition of non-polysyllabic words with 4, with 5 and with 6 syllables; and in spelling tests, as for CF/G type errors in word dictation, pseudoword dictation and figure dictation; as for OAS-type errors in proofs of word dictation, dictation of pseudowords and dictation of figures; for CF/GDC type errors in word dictation tests, pseudowell dictation and figure dictation; as for the APIA type errors in the dictation test of figures; as well as for errors of type OA in the proof of dictation of figures and for errors of types OP and AP in the proof of dictation of sentences. The GI subjects who underwent the intervention obtained better performance in the post-test compared to the pre-test. Conclusion: the elaborated program was effective and can be used as an intervention instrument based on scientific evidence that helps improve performance in decoding and coding of students with dyslexia.
