RESUMEN
INTRODUCTION: Transcranial direct current stimulation (tDCS) modulates cortical activity and potentiates functional gains achieved during therapeutic protocols. The aim of Integrative Speech Therapy Protocol is to rehabilitate speech in patients with impairments regarding neuropyschomotor development by combining oral motor stimuli, specific articulatory production, and the stimulation of phonological aspects of language. OBJECTIVE: Investigate the effect of transcranial direct current stimulation combined to integrative speech therapy in a child with cerebral palsy. METHODS: We performed a case study with tDCS and speech therapy in a patient with cerebral palsy and apraxia of speech. To assess the patient's speech, we used a parameterized test for the Brazilian Portuguese speech - ABFW. The CFCS and Vicking Speech Scales presented level IV and III, respectively. The patient underwent two periods with ten stimulation sessions each: first with anodal stimulation over Broca's area; and second over the left dorsolateral prefrontal cortex. Two indices were calculated: the percentage of consonants correct; and percentage of consonants correct-revised. Descriptive statistics were employed for the clinical data. For the outcomes, changes in each score were calculated as the difference in pre-intervention and post-intervention using Wilcoxon-Mann-Whitney test. RESULTS: Increases were found in percentage of correct consonants indices as well as to produce two-syllable and three-syllable words after both types of stimulation, characterized mainly by correct vowels that marked the presence of the syllable. Number of phonemes increased 0 to 4 at first the stimulation and 4 to 10 at the second. CONCLUSION: The combined-therapy program contributed to improve the speech rehabilitation results in a patient with cerebral palsy.

OBJECTIVE: The aim of the present study was to analyze the use of anodal tDCS of the cerebellar region combined with treadmill training to improve balance and functional performance in children with ataxic cerebral palsy. DESIGN: Single-blind, sham-controlled, crossover, pilot study. SETTING: Rehabilitation center and research motion analysis laboratory. PARTICIPANTS: Children (N = 6) with ataxic cerebral palsy and balance deficit. MAIN OUTCOME MEASURES: Static balance (oscillations of the center of pressure), functional balance (Pediatric Balance Scale) and functional performance (Pediatric Evaluation of Disability Inventory) were evaluated. RESULTS: Significant reductions occurred in oscillations of the center of pressure with eyes closed after active anodal tDCS only. The effects of treadmill training on functional balance and functional performance in mobility were maintained in the active tDCS group only. CONCLUSION: These preliminary data support the notion that anodal tDCS of the cerebellar region combined with treadmill training improves balance in children with ataxic cerebral palsy.
