Study information

Primary study designInterventional
Study designMulticentre, randomised active controlled, parallel group trial
Secondary study designRandomised controlled trial
Scientific titleThe effect of multi-level botulinum toxin treatment and intensive rehabilitation on walking ability in children with cerebral palsy
Study acronymThe BOLIEN project
Study objectivesMulti-level botulinum toxin-A (BTX-A) treatment of the lower extremities in combination with comprehensive rehabilitation leads to an improvement in mobility of children with cerebral palsy.
Ethics approval(s)Ethics approval received from the local ethics committee.
Health condition(s) or problem(s) studiedCerebral parese (cerebral palsy)
InterventionGroup A: multi-level BTX injections 6 weeks after the first assessment
Group B: multi-level BTX injections 30 weeks after the first assessment

Intervention:
Multi-level treatment with botulinum toxin A (BTX). Possible target muscles for a multi-level treatment are the psoas, medial/lateral hamstrings, hip-adductors, rectus femoris, triceps surae, and tibialis anterior/posterior unilateral or bilateral. Starting one week after the multi-level BTX-injections, the patients will be treated by a physiotherapist according to a standardised treatment protocol for 12 weeks.

Randomisation:
The patients will be randomised into two groups in a multiple baseline design. Follow-up measurements will be performed at 6, 12, 24 and 48 weeks.
Intervention typeDrug
PhaseNot Specified
Drug / device / biological / vaccine name(s)Botulinum toxin
