[Specific psychomotor organization in a child with phocomelia].

The authors follow the specific development of a child with phocomelia. Psychomotoric organization was analyzed in the period prior to starting school and before the child became literate. The existence of specific forms and outlines of catching movements was established. The lower extremities developed a compensatory--fine motorics mechanism of toe abduction. A drawing of a human figure expressed the specific experiencing of the body scheme as the "losing" of the upper extremities. Left-handedness was discovered. Typical difficulties exist in the forming of the number conception. Preparations are being done for the mastering of the use of the intelectual prosthesis-computer.
