The unusual case of a 4-year-old girl with the probable diagnosis of kernicteurs, having psychomotor retardation and showing a reversal of functions between the lower and upper extremities is reported. Submitted to adequate training the patient improved markedly, and at a 3 months interval, she already used satisfactorily her hands, could stand leaning against the wall and was able to walk with support. The findings in this case suggest that at least some of the lost functions which do not recover spontaneously are able to return through an adequate reeducation program.
