Splints are used in adjunction to physiotherapy, in order to prevent deformities, or to treat them when they are present. They are worm mostly at night, but day splints may be necessary in some cases.
Splints and orthosis must be costum-made in order to be comfortable. A splint which causes pain or skin irritation is likely to produce the opposite effect, i.e. to increase the spasticity. They must be regularly checked, especially in the growing child.
