Evaluation of rotational gait abnormality in the patients cerebral palsy

Internal rotation of hip is commonly seen in children with cerebral palsy. Existing muscle imbalance causes persistence of femoral deformity, which ma y contribute to rotational asymmetry. In cerebral palsy, gait deviations ar e the result of dynamic and static components, both caused by muscle imbala nce. In this study we investigated the predict ability of hip rotation in g ait from the measurement of anatomic deformity. Computed tomography (CT) me asurements of femoral anteversion and physical examination data failed to p redict the hip rotation in gait. However, tibial (CT) measurements and phys ical examination data highly correlated with tibial rotation in gait. We co nclude the dynamic component of hip rotation during gait is significant, as anatomic deformity did not predict gait deviations.
