[Psychomotor delay and psychiatric diagnoses in special education students]

76 first grade children of a special school for learning disabled were tested for specific developmental disorders of motor functions (SDDM). 15 children (19.7%), boys and girls proportionately, had a SDDM. This is a substantial increase compared to the unselected population. 8 children (15.5%) suffered from a specific disorder of body coordination and low finger-eye coordination. 4 children (5.3%) were found to have specific disorders of motor functions and specific language retardations. Isolated disorders of hand coordination were not found. 31% of the children with SDDM suffered from psychiatric disorders. Roughly the same percentage of psychiatric diagnosis was found in children without disorders of motor functions. A total of 24 children (33%) had impaired physical coordination: these children had significantly higher total scores in the Child Behavior Checklist (CBCL). Though this questionnaire was not sensitive for detection of disorders of motor functions.
