Adequate treatment of pathologies that alter normal gait, for example, spastic encephalopaties such as cerebral palsy, require precise identification of their movement patterns and causes, in order to select the most effective treatment. Objective: To identify and characterize transverse plane kinematic patterns of the pelvis as a compensatory response to lower limb deformities in pediatric patients with spastic hemiplegias. Methods: 66 patients with spastic hemiplegia subtype motor dysfunction, from the Hospital Ortopédico Infantil (HOI) at Caracas, Venezuela, were studied between 1999 and 2004. A gait analysis was performed in each patient following the HOI’s protocol. Deviations of pelvic movements were measured on all three planes to the kinematics gait patterns obtained, Measurements of foot progression and hip rotation (femoral anteversion) were achieved via clinical examination. Results: Movement patterns on spatial planes were obtained and characterized in terms of its deviations, then classified in four wellfeatured subtypes: Type I, Type II, Type III y Type IV. Special emphasis was placed on analysis of deviations in the transverse plane. Conclusions: Findings for sagital and coronal planes are consistent with those reported by the literature. However, movement patterns that are consistent with bone deformities in the ipsilateral limb were demonstrated for transverse plane, and the pelvic coping responses for that plane tend to maintain both feet aligned with the gait progression line.
