The article describes modern modeling of physical rehabilitation processes for persons with musculoskeletal system disorders, it is discovered a significant deficiency of this aspect in modern rehabilitation systems. Structured and logically constructed rehabilitation system model is designed, which includes four effective units: physical development monitoring and spastic motor disorders monitoring (I); strategies and tactics of corrective actions (II); spastic motor disorders form correction (III). The last include: gaming, hyper-correction, contraindications, sufficient exercises repetition, objectivity, individual differentiation of the load; control and adjustment of the correction process (IV). It is briefly revealed the internal structure of each these blocks in the form of conditional sections; the interaction between blocks and sections of the working model is shown to achieve maximum efficiency in the whole system. The structuring formation factor of rehabilitation model system is the purpose of its activity, the specific target results that are planned to be achieved. The pre-designed working model of the correction system of movement disorders spastic forms of tender age children by physical education means will be tested in the process of forming a pedagogical experiment.
