Autistic disorder is a developmental disorder which appears in the first three years. It starts in the childhood and lasts throughout the person's life. Autism is defined by distracting symptoms in a child's development which affect social interaction and communication, stereotypical behaviour, limited interests. Autistic children are often disconnected from the outisde world due to inability to express their emotions and limited sensory reception. They are often frustrated and dissatisfied and such behaviour has a negative impact on the quality of their lives. Communication disorder causes difficulty in making friends and establishing social contact, in their own families as well as outside the family circle. Autistic child's play is made up of stereotypical hand movements. They play by observing their hands, moving them towards and away from their faces. A lot of autistic children have specific abilites which set them aside from other children. Those can be musical, artistic or mathematical abilities which enable them to sing or calculate with ease. It is important to intervene as early as possible so as to prevent negative symptoms and behavioural patterns. Before such intervention it is necessary to carry out detailed diagnostics and assess the disorder by certain tests. After that the child needs to go into therapy, to be involved into the local community and it is important to adapt the environment to the child. It is necessary to set the goals of the therapy and decide on the procedures which are individally adapted to each child. Physical therapy should be focused on muscle tone, spasm, balance, endurance and strength. Other types of therapy will affect child's socialisation and communication. Rehabilitation of autistic children also involves educating their parents, so they can implement therapeutic procedures at home. The object of this thesis is to line out he therapeutic procedures that are implemented to help the autistic children. Another objective is to show the role of a physical therapist in treating autistic disorder.
