The purpose of this study is to investigate the effect of a very specific hydrotherapy programm on the movement from lying down to sitting position for children with CP

40 children aged 5-11 years with cerebral palsy and difficulty in the transfer activity from lying down to sitting position were randomly divided into 2 groups of 20 children, a land group and a water group. The children of the land attended a neurodevelopmental treatment program and the water group a very specific program in hydrotherapy on combined rotation at all levels. The water program was implemented by specialized physiotherapists in hydrotherapy. The duration of the program for both groups was 3 months. On the first and last day of the intervention, an evaluation of all children was performed using the GMFM and PBS evaluation tests of the evaluation parameters of the transfer from the lying position to the sitting position.
