New Therapeutical Perspectives in Cases of Phonological Disorders

Universidade Federal de Santa Maria24 enrolled

Overview

The aim of this study is to verify phonological and auditory aspects of children submitted to traditional phonological therapy, phonological therapy using a software and placebo therapy in children with phonological disorders.

The study will provide different therapeutic approaches for cases of phonological disorders, the classical approach would be mediated by Cycles Model, innovated approach is performed by means of an intervention speech software-SIFALA, there will still be the group that does not receive any of the proposals therapies that will be the placebo group.The study will provide 25 sessions for each group, with 30 minutes in each group. At the end of these sessions, the placebo group will receive one of the therapeutic approaches. With these three study groups, the investigators understand in what manner to obtain correct sounds is more effective.

Interventions

Traditional Phonological TherapyBEHAVIORAL

Phonological therapy based on generalizing the sounds presented by figures, repetition and naming words.

Software Phonological Therapy- SIFALABEHAVIORAL

The phonological thearapy of this group will be based on software use with phonological model already developed, using naming and repetition of sounds.

Placebo TherapyBEHAVIORAL

No intervention to improve speech.

Outcomes

Primary Outcomes

Percentage of Consonants Correct (PCC) Pre-treatment and Post-treatment Phonological Instrument

The percentage of correct consonants corresponds to the number of phonemes produced by the child, evaluated initially before starting treatment and at the end of treatment. The variable of this calculation is based on the percentage which is determined at what phonological level of disorder the child is at. It is expected that at the end of treatment the percentage of correct consonants will increase due to the therapy stimuli offered.

Time frame: 10 weeks

P300- Long-latency Auditory Evoked Potential

Electrophysiological evaluation of the auditory pathway through the protocol, Pretreatment and Post-treatment P300 waves were analyzed by the latency according to the parameters of MacPherson (1996). The electrophysiological protocol was performed before and after therapy. The marking of the waves was judged by specialist judges in the field of audiology. The variable that predicts P300 latency is quantified in milliseconds (ms

Time frame: 10 weeks.
