Replication Data for: Lambrechts et al (2025) - Botulinum Neurotoxin A-Induced Muscle Morphology Changes in Children with Cerebral Palsy: A One-Year Follow-Up Study.

This is a longitudinal dataset consisting of macroscopic muscle (size) data from the medial gastrocnemius over a one-year period. The data is available for children with cerebral palsy (CP) who received botulinumtoxin (BoNT) treatment and children with CP in a control group. Cross-sectional data from children in a CP reference group is also included. Macroscopic muscle parameters were assessed through 3D freehand ultrasound and included muscle volume, anatomical cross-sectional area, muscle belly length and echo-intensity.
