Motor control of the lower extremity musculature in children with cerebral palsy

► We quantified torque steadiness in children with cerebral palsy and typical children. ► Children with CP had greater variability in their torque steadiness. ► Children with CP had greater variability at the ankle than the knee and hip joint. ► Children with CP had a more regular steady-state torque pattern. ► The EMG of children with CP was composed of higher harmonics.
