[Botulinum toxin A in children with infantile cerebral palsy: indications and treatment concepts].

Botulinum toxin A treatment in children with cerebral palsy is now well established as a safe and effective therapy option. However, a standardised injection strategy is still lacking. There is no doubt concerning the necessity for long-term therapy to cover the duration of motor development as well as for adequate prevention of fixed contractures. The appropriate dose and treatment concept to be used, however, is still controversial. The modern BoNT-A treatment concept must combine safety and efficacy with the availability of this treatment option throughout the duration of growth in these children. Consequently, in order to provide the best possible support for motor development at each individual motor milestone and using moderate dose recommendations, the "Key-Muscle Concept" has been developed.
