Abnormalities in the uninvolved lower limb in children with spastic hemiplegia: the effect of actual and functional leg-length discrepancy.
We assessed the pattern of gait in children with spastic hemiplegia and a leg-length discrepancy, particularly in relation to the uninvolved limb. The kinematics of the uninvolved limbs were compared with the pattern in normal children. The uninvolved limbs in children with hemiplegia and a significant leg-length discrepancy were compared with the uninvolved limb in those children who did not have a leg-length discrepancy. We found that the involved and uninvolved legs in patients with hemiplegia had characteristic patterns that were significantly different from normal. The kinematics of the involved leg were not affected by the presence of a leg-length discrepancy. The abnormal pattern in the uninvolved limb was more exaggerated in children with a leg-length discrepancy. The abnormal sagittal plane kinematics in the uninvolved lower limb in hemiplegic children appears to be related to the presence of an actual or functional leg-length discrepancy and have not previously been described. Our findings suggest that attention be paid to the functional and actual leg-length discrepancy that exists in these children, and early consideration be given to epiphysiodesis of the uninvolved limb.
