  1. GMFCS: gross motor function classification system, Extr.: extremities, SDR: selective dorsal rhizotomy, ITB: intrathecal baclofen. The (%) is calculated from the number children at each GMFCS level
  2. An intervention is only registered once pr child, however, one child may have had more than one type of intervention/surgery
