The objective of the study was to work out an effective model of complex help to children with severe movement disorders. We examined 440 preschoolers with children cerebral palsy with severe movement disorders and 70 children with mild movement disorders. Functions of motor, emotional-personal and cognitive spheres and independence status with determination of 5 levels were studied in 47 patients. Three groups (from the group without concomitant (sensor, intellectual etc) disorders to the group with most severe disorders) were singled out. The authors characterize the model as an open integral system of methods, tools and ways providing the adaptation of children in response to external circumstances and changes in the state of patients. The creation of a correction-developing environment, consisting of 3 components: spatial-objective, technological (methodological) and social, is discussed. We present results of the development of children, evaluated by the following indices: general technique, sensory perceptive development, social adaptation, anxiety, cognitive activity, from 1997 to 2008. The 15 year follow-up demonstrated the stability of achieved positive results.
