Optimal Dose of Botulinum Toxin A to Release Spasticity of Triceps Surae in Children with Cerebral Palsy / 中国康复理论与实践

ABSTRACT

@#Objective To determine the coefficient in the formula of the optimal dose of botulinum toxin A(BTX-A) to treat spastic cerebral palsy(CP).Methods58 CP children(male 38,female 20,mean age 59.3±24.6 months,range 27 to 144 months) were divided into A,B,C,D and E five groups according to used coefficient and treated by BTX-A with different doses to release the spasticity.ResultsAccording to the improvement of motor function,the BTX-A dose of the group D was optimal.According to the effective endurance,the BTX-A dose of the group C was optimal.The optimal coefficient was 1.8.ConclusionThe formula of the optimal BTX-A dose injected in triceps surae is dose =(1+1.8×MAS score)×body weight.
