The purpose of this study was to determine whether children with mild spastic diplegic cerebral palsy (CP) could be differentiated from those with idiopathic toe-walking (ITW) based on an obligatory coactivation during voluntary contraction of the quadriceps or gastrocnemius. Twenty-four subjects participated in this study, eight children with mild spastic diplegia CP, eight with ITW, and eight age-matched controls. Measurements included passive range of motion and surface electromyographic recordings of the lateral quadriceps and lateral gastrocnemius.
