Devices that help individuals move about more easily and communicate successfully at home, at school, or in the workplace can help a child or an adult with cerebral palsy overcome physical and communication limitations. There are a number of devices that help individuals stand straight and walk, such as postural support or seating systems, open-front walkers, quadrupedal canes (lightweight metal canes with four feet), and gait poles. Electric wheelchairs enable more severely impaired adults and children to move about successfully.
The computer is probably the most dramatic example of a communication device that can make a big difference in the lives of people with cerebral palsy. Equipped with a computer and a voice synthesizer, a child or an adult with cerebral palsy can communicate successfully with others. For example, a child who is unable to speak or write but can make head movements may control a computer using a special light pointer attached to a headband.
