Trends observed in bilateral cerebral palsy during a thirty-year period: A cohort study with an ICF-based overview.

Background: To describe trends observed across thirty years in demographic and clinical characteristics and rehabilitation of patients with bilateral cerebral palsy.

Methods: This retrospective study includes 464 (261 M and 203 F) inpatients with bilateral cerebral palsy, born from 1967 to 1997 and discharged from an outpatient rehabilitative facility from 1985 to 2015. Data concerning the health profile were collected from medical reports and organized in the domains of Body Functions and Structure; Activity and participation and Personal and Environmental factors as proposed in the International Classification of Functioning Disability and Health (ICF). The trend observed over the three birth decades was discussed.

Results: The duration of the rehabilitative treatment decreased across decades approximately by two years per decade (from an initial 16.2 yrs to 12.3 yrs). Across the decades the rate of quadriplegia decreased, whereas rates of diplegia increased; spasticity was the prevalent observed motor type for all decades. The most frequent musculoskeletal disorder involved the middle inferior part of the body; among comorbidities a steady decrease in psychiatric disorders was found. With respect to the first decade a slight improvement was observed in the gross motor functioning and in the hand dexterity. No particular trend was observed concerning communication abilities. An increase in the use of pharmacological and surgical treatments for motor symptoms was observed.

Conclusion: This study presents and describes the functioning of a large sample of Italian patients with bilateral CP on the basis of the ICF framework and it discussed the trend observed across decades.
