Value of the data •HD-EMG data can be used to evaluate muscle activation in Cerebral Palsy on a motor unit level. •The longitudinal data available for children with Cerebral Palsy facilitates evaluating the effect of Botulinum Neurotoxin-A treatment on muscle activation on a motor unit level. •The torque data available allows for the investigation of force coordination and strength characteristics (e.g. rapid force development and impulse) in children with and without CP. •Data was collected from age- and gender-matched typically developed children. •The data available for both limbs in some participants of the TD group allows for between limb comparisons in TD children.
