Evidence-based approach of the use of Botulinum toxin type A (BTX) in cerebral palsy.

A systematic review with the Sachett model of evidence-based medicine of the use of Botulinum toxin type A (BTX) for intervention in children with Cerebral Palsy (CP) is highlighted. Currently, the evidence showed that BTX is useful for treating pes equinus due to spasticity of the gastrocnemius-soleus muscles. However, careful patient selection and goals of treatment have to be addressed. More multi-centre clinical trials with standardized protocols are needed before widespread recommendation of the use of BTX in treating spasticity in CP can be made.
