Prognosis for gross motor function in XXXX : creation of motor development curves.

@entity1 @entity73 @entity306
CONTEXT: Lack of a valid classification of severity of @entity306 and the absence of longitudinal data on which to base an opinion have made it difficult to consider prognostic issues accurately. OBJECTIVE: To describe patterns of gross motor development of @entity1 with @entity306 by severity, using longitudinal observations, as a basis for prognostic counseling with parents and for planning clinical management. DESIGN: Longitudinal cohort study of @entity1 with @entity306 , stratified by age and severity of motor function and observed serially for up to 4 years during the period from 1996 to 2001. SETTING: Nineteen publicly funded regional @entity1 's ambulatory rehabilitation programs in Ontario. @entity1 : A total of 657 @entity1 aged 1 to 13 years at study onset, representing the full spectrum of clinical severity of @entity73 in @entity1 with @entity306 . MAIN OUTCOME MEASURES: Severity of @entity306 , classified with the 5-level Gross Motor Function Classification System; function, formally assessed with the Gross Motor Function Measure (GMFM). RESULTS: Based on a total of 2632 GMFM assessments, 5 distinct motor development curves were created; these describe important and significant differences in the rates and limits of gross motor development among @entity1 with @entity306 by severity. There is substantial within-stratum variation in gross motor development. CONCLUSIONS: Evidence-based prognostication about gross motor progress in @entity1 with @entity306 is now possible, providing parents and clinicians with a means to plan interventions and to judge progress over time. Further work is needed to describe motor function of adolescents with @entity306 .
