Cerebral palsy (CP) refers to a group of disorders that can disturb muscle tone, movement, balance, and posture. 1 With complicated aetiology, CP is the most common motor disability of childhood. 2 Spasticity is one of the dominant clinical symptoms of CP, which can contribute to limitations in functional activity, physical fitness, and social participation of children with CP to varying degrees. 3 The latest evidence suggests that botulinum neurotoxin A (BoNT-A) is an optimal way to reduce spasticity in this group by inhibiting acetylcholine release from the neuromuscular junction. 4,5 The decrease of spasticity can help produce opportunities to improve motor function and posture, reduce pain related to spasticity, and ameliorate symptom management.
