Nosology of spastic tetraplegic cerebral palsy: clinical review of fifty cases.
The aim of this study is to contribute to the definition of tetraplegic cerebral palsy (TCP) and to verify the classification criteria currently used by reviewing the clinical and neurological aspects of 50 children having non-progressive encephalopathy with neurological involvement of 4 limbs (symmetric 4-limb type, side-asymmetric type, upper-limb dominated type with or without dystonic traits). All severe diplegic patients, i.e. less upper than lower limb involvement and patients with dystonic hyperkinetic syndrome without spastic features were excluded. The data were supplied by the hospital records, evolution of motor performance and the presence or absence of epilepsy, visual problems, language disorders, intellectual impairment. All the children underwent: neurological examination, functional assessment, cognitive evaluation. Severe motor impairment was found in 80% of the patients, whose clinical characteristics led to a diagnosis of severe TCP or "true TCP" according to Hagberg, whereas 20% of them showed mild to moderate impairment with a more favorable prognosis. This group of patients complied with the classification of Michaelis who defined the quadrispastic CP types more broadly and delineated five subgroups also including cases with milder involvement (side-dominated, three-limb dominated tetraparesis). The intellectual assessment showed that, in the severely affected patients, only a small percentage had severe intellectual impairment (IQ less than 50, 37.5%), which contrasts with published data on this pathology, while the majority of the subjects showed moderate (25%) or mild intellectual impairment (32.5%) or normal cognitive function (5%).(ABSTRACT TRUNCATED AT 250 WORDS)
