[The relationship between severity of spastic diplegia and laterality of the cerebral function].
Seventeen children with clinical evidences of preterm birth and spastic diplegia (SD) were studied about the relationship between clinical severity and laterality of cerebral function. The result showed the patients with the left-handed SD were more serious than those with the right-handed in their intelligence and activity of daily living. As the severity increased, motor difficulty was also observed at upper limbs, and especially spasticity was detected at the right hand. The dichotic listening test showed the right ear dominance only in the patients with the right-handed SD. MRI examination was performed in 10 cases, and periventricular leukomalacia (PVL) was detected in all cases. There was few correlation between PVL and clinical laterality. We speculated that right-hand spasticity which was seen in severe cases was due to the fragility of periventricular structure in the left hemisphere.
