Botulinum toxin injections are a new treatment for limb spasticity. Intramuscular injections can be performed in spastic muscles; efficacy occurs one or two weeks later, with a mean duration of three months. Clinical action is related to chemical denervation of presynaptic motor end nerves by the botulinum toxin. ⋯ Kinematic parameters of gait are improved in lower limb spasticity, especially in children with cerebral palsy disorders. There were no reports of serious side effects. Botulinum toxin is a safe and effective treatment of localized spasticity in adults and children.
