Each patient was individually treated with GES protocol of Raymer and colleagues during 10 sessions. The obtained data were statistically analyzed by visual analysis, the calculation of effect size and the slope, trend and level changes.
Results
The amount of effect size and Linear Trend line of correct responses percentage of trained words in confrontational naming task after intervention in N.Z were, respectively 3.9 and 4.5 and in R.B were 2.33 and 6.27. Both patients had improvements in naming of trained words and control words. Improvements of two patients who were examined one week later were maintained at a higher level than baseline.
