The research assistant will visit both groups at the start of the trial and every 3 months. At each visit they will (a) check the position the child adopts in the standing frame (b) check footwear and splints for use and fit (c) check the progression of treatment (d) check and record any changes to their additional care routine by the treating therapist. Feedback about problems in footwear / splinting will be passed onto the child's treating therapist.
