Clinical impairment scores and sagittal plane kinematics of children with cerebral palsy

These files accompany the article entitled "Are spasticity, weakness, selectivity, and passive range of motion related to gait deviations in children with spastic cerebral palsy? A statistical parametric mapping study" with DOI:10.1371/journal.pone.0223363. They contain retrospective data, acquired through the Clinical Motion Analysis Laboratory of the University Hospitals Leuven (Medical Ethical Committee of University Hospitals Leuven - s56036). This research project provided permission to use retrospective patient data that have been acquired during standard medical care, under the condition that all data would have been anonymized a priori, unless the patients had specifically asked to not be included in any study. Two different datasets are included from: a) children with unilateral cerebral palsy (uCP - n=167) and b) bilateral cerebral palsy (bCP - n=200). These datasets contain clinical impairment scores of spasticity, weakness, selectivity and passive range of motion measured at the level of the hip, knee and ankle joints for muscles acting in the sagittal plane, as well as the sagittal plane kinematic curves of these patients (i.e. pelvis, hip, knee and ankle joint motions). The impairment scores were inspected at a total level (i.e. composite scores, as sum of all individual impairments) or at a joint level. Statistical non-parametric mapping was used to assess: a) the relationships between the composite impairment scores and the vector of the four joints, as well as the individual joint motions and b) the relationships between the joint impairment scores and the individual joint motions. All analyses were performed separately for children with uCP and bCP.
