Tactile extinction in childhood hemiplegia.
Tactile extinction was investigated by the Quality Extinction Test (QET) of Schwartz in 39 patients, 34 of whom had congenital hemiplegia and five early-acquired hemiplegia. Extinction values were significantly higher in hemiplegia patients than in controls and usually contralateral to the side of brain damage, except for four cases with right hemiplegia. Values were also higher in males than in females. There were no significant differences between patients with left and right hemiplegia, and no correlations between extinction and IQ or the presence of epilepsy. There was a correlation between QET scores and neuroradiologically proven cerebral atrophy. The meaning of extinction in hemiplegic patients and the principal theories regarding the pathogenesis of neglect are discussed.
