dear Sisone,
The following recommendation is part of the Dutch Guidelines for treating children with CP:
In the treatment of gait problems in children with CP, BTX-A can be considered as treatment option as long as it is combined with exercise therapy and casks and or orthotics as follow up treatment.
this implies that:
therapy (45-60 minutes) frequency 3x week at a minimum
children should be put in stretched positions at home as well
night orthosis (6-8 hrs of stretching) needs to be part of the treatment
Training has to be functional and in various circumstances and should include all functions, sitting down, standing up, crouching, walking etc.
good luck
Esther
