Botulinum toxin A (Btx- A) is a highly effective treatment in the management of spasticity. The first reported success of use of Btx-A in children with cerebral palsy was made in 1993 by Koman et al. Subsequently, randomized controlled studies on children with spastic type of cerebral palsy has documented that Btx-A is effective and safe in the management of muscle spasticity in children with CP. There is an implicit, and as of yet, unproven assumption that there is no indication for this treatment in the adult CP-population.
