Introduction: Participation in life situations is an important goal in children with hemiplegic cerebral palsy (HCP), which were submitted a multiple interventions, including botulinum neurotoxin type A (BoNT-A).

Methods: Cross-sectional study in HCP cohort treated with BoNT-A. Data obtained from charts and clinical evaluations. Child Behavior Checklist (CBCL) was used as participation in life situations. All statistical tests considered p<0.05.

Results: Sixty-six patients concluded all evaluations. Patients classified as normal in Activities scale on CBCL had younger seat acquisition and better Mini-Mental, self-care, communication, cognition and total WeeFIM scores and verbal and total IQ. Patients with perinatal insult were predominantly classified as normal in Activities CBCL. Children from families without full disability pension, more educated mothers and who lived in Curitiba were normal in Activities CBCL. Patients with varo foot were worse in Activities CBCL. Patients classified as normal in Social CBCL had early gait acquisition. Patients normal in Academic CBCL had better education, adherence and current Mini-Mental, muscle strength, hand movement velocity tasks, PRS, arm Brunnstrom, SCALE, SCAUE, self-care, communication, cognition and total WeeFIM and verbal and total IQ. Those classified as normal in Total Competences CBCL had better scores in initial PRS and UPRS; and better current Mini-Mental, SCAUE and self-care, communication, cognition and total WeeFIM scores. Second offspring children had better Total Competences on CBCL.

Conclusion/Discussion: HCP with better function and independence had more participation in life situations. Low income, mother education, third or more offspring, pre natal insult and varo foot were factors of unfavorable prognosis.
