ABSTRACT
We evaluated the safety and effectiveness of botulinum toxin A (BoNT/A) in the treatment of spasticity in 20 children with spastic diplegic cerebral palsy (CP). All the patients received injections in the gastrocnemius and soleus, and 15 received injections in the adductors. The total dose varied from 70 to 140 U (99.75±16.26 U), or 7.45±2.06 U/kg per patient. The treatment improved the patients' walking and gait pattern significantly. There was also a significant alteration in the heel-ground distance and increased motion of the ankle joint. These structural changes in the feet were sustained until the end of the follow-up, although the same was not observed for the functional parameters. Three patients complained of weakness in the lower limbs. In conclusion, BoNT/A is safe and effective when used in a single session of injections and produces a sustained structural modification of the lower limbs. However, functional changes are temporary and are only observed during the peak effect of the drug.
RESUMO
Para avaliação da segurança e eficácia do tratamento com toxina botulínica A (TB-A) na espasticidade na paralisia cerebral (PC), foram selecionadas 20 crianças com a forma diplegia espástica. Todos os pacientes receberam injeções nos gastrocnêmios e sóleos, 15 receberam doses nos adutores da coxa. A dose total variou de 70 a 140 Us (99,75±16,26 U), 7,45±2,06 U/Kg por paciente. O tratamento com a TB-A melhorou significativamente a deambulação e o padrão de marcha. Houve também significativa alteração da distância tornozelo-solo e aumento da amplitude de movimento da articulação do tornozelo. Essas mudanças estruturais dos pés se mantiveram até o final do acompanhamento. O mesmo não foi observado com parâmetros funcionais. Três pacientes apresentaram fraqueza em membros inferiores. Conclui-se que a TB-A, em uma única aplicação, é segura e eficaz. Há modificação sustentada da estrutura motora dos membros inferiores, porém mudanças funcionais são temporárias, durante o pico de ação do medicamento.
