Spasticity in children cerebral palsy has its own peculiarities due to the presence of pathological tonic reflexes, pathological sinkinetic activity during arbitrary movements, disturbance of coordinative interactions of muscle synergists and antagonists, increase of total reflex excitability. Physiotherapeutic methods, massage, therapeutic exercises, kinesitherapy, biological feedback training (BFT), methods of orthopedic correction, neurosurgery are widely used in the treatment of spasticity. The use of botulinum toxin type A is a new effective approach to the treatment of spasticity that improves motor functions and quality of life of children with children cerebral palsy. It is being used in the treatment of children and adolescence in a polyclinic unit of the Moscow psychoneurological hospital since 2001. The experience of treatment with botulinum and wide implementation of this method indicated that botulinum toxin injections in the complex treatment of spasticity allow to optimize approaches to treatment of children and adolescence with children cerebral palsy and to increase significantly the quality of medical-social rehabilitation of patients.
