[Mirror movement. Review of 11 cases]

The disturbance of mirror movements is a little known disfunction of the movement in which one extremity reproduces simultaneously the movements carried out by the other extremity. It can have very different etiologies. We have observed the clinical histories of eleven children who suffered from this disturbance, with the aim of contributing to a further knowledge of this subject. The conclusions of our observation are: 1) Clear preference for male sex. 2) Great etiological variety. 3) High incidence of neuropsychological disturbances associated, as well a large variety of them. 4) The most useful complementary exam from the underlying process to the disturbance of mirror movements is the craneal CAT; although the alterations found are not especific and probably not pathogenetically related with the disturbance.
