RCT on Interactive Computer Play on Trunk Control in CP

All children will be calibrated using the Tymo in a static sitting position in each treatment session. The amplitude of the force and weight distribution generated by the child between the two sides of the body will be recorded. This information will be used to set up the Tymo as a training module (the intervention) by the software, in which the child will move the trunk forward, backward and sideways to participate in a computer game in sitting. The child will choose which game they want in each treatment session and they have to stay on the same game for at least 10 minutes before changing to another game.
