Fig. 3From: Clustering trunk movements of children and adolescents with neurological gait disorders undergoing robot-assisted gait therapy: the functional ability determines if actuated pelvis movements are clinically usefulKinematic response of the patients per cluster: The participants were assigned to 3 clusters. Each line represents the mean of the respective angle over the gait cycle beginning with the left heel strike of a single subject. The black line represents the reference trajectory from children and adolescent treadmill gait. The clusters were labelled based on how well they correlated with the reference data. A positive angle indicates that the right (contralateral) joint is higher than the left (ipsilateral) joint. The dashed line marks the approximate transition from stance to swing phase of the left legBack to article page
