Short Term Follow-up of a Botulinum Toxin Intervention in Children With Spastic Cerebral Palsy

This study investigates the effect of integrated Botulinum Neurotoxin A (BoNT) treatment on morphologic muscle and tendon properties, spasticity, joint stiffness, joint range of motion, muscle strength, gait and gross motor function. The integrated BoNT treatment combines BoNT-injections with serial casting and intensive physical therapy, as previously described by Molenaers et al. The current study will include 30 children who are clinically scheduled for BoNT treatment in the medial gastrocnemius and/or the semitendinosus muscle in the intervention group and 30 children in a control group who will receive usual care within a time span of 3 months.
