Introduction: Children with hemiplegic cerebral palsy (HCP) were submitted an expensive and long time treatment, including botulinum neurotoxin type A (BoNT-A), with goal of better function, independence and participation in life situations.

Methods: Cross-sectional study in HCP cohort treated with BoNT-A. Data collected from charts and clinical evaluations. The Gross Motor Function Classification System Expanded and Revised (GMFCS-ER), Manual Ability Classification System (MACS) and Communication Function Classification System (CFCS) were used as classification tools. Dimension E of the Gross Motor Function Measure (GMFM-E) was used as functional measure and Child Behavior Checklist (CBCL) as participation in life situations. All statistical tests considered p<0.05.

Results: Sixty-six patients concluded all evaluations. Patients classified as level I on GMFCS-ER were classified as normal in Academic and Activities scales on CBCL more frequently. Level I on MACS was frequently classified as normal in Academic scale on CBCL. Level I on CFCS was classified as normal in Academic scale on CBCL more frequently. Patients with higher means in dimension E of GMFM were classified as normal in Activities, Social and Academic scale on CBCL; and had higher scores in Total Competences and lower in social problems on CBCL.

Conclusion/Discussion: Level I in all classification tools is factor of good prognosis of participation in life situations, however higher means in GMFM-E is the best tool to foresee participation.
