The term diplegia should be enhanced. Part I: a new rehabilitation oriented classification of cerebral palsy.

The classification systems for cerebral palsy (CP) need to be continuously updated, according to specific aims and to significant changes observed over the years in the panorama of CP. A simplification of CP categories, abandoning the use of the term diplegia, has been recently suggested. Conversely, in this paper a new proposal for classification of CP is briefly presented, where special attention is given to diplegia which is suggested to be divided into four main clinical forms, according to the patterns of walking observable in these subjects. The proposed classification was applied to a large population of 213 subjects with diplegia, among 467 cases of CP admitted to two reference centres for this disorder. The relative incidence of the four forms is reported. The adopted classification criteria, based on a primary ability of professionals working in rehabilitation, i.e. observation capacity, makes this approach simple and easy to use at all levels of the rehabilitation services for CP.
