100 patients over 2 years of age with a diagnosis of cerebral palsy will be included in the study. Demographic information form prepared for the study in terms of demographic information such as age, gender, clinical type of cerebral palsy, drugs used, comorbid diseases will be completed. Communication Function Classification System and Functional Communication Classification System will be used to evaluate patients' communication skills. In addition, patients; The Gross Motor Function Classification System for cerebral palsy and based on child-initiated movements with emphasis on sitting, displacement and mobility, and to hold objects during the daily activities of children with cerebral palsy. The Manual Ability Classification System, which classifies how they use their hands, will also be completed.

Demographic information form, Communication Function Classification System, Functional Communication Classification System, The Gross Motor Function Classification System and Manual Ability Classification System will be filled in for the patients.

The Functional Communication Classification System was designed to classify how children with cerebral palsy between the ages of four and five communicate on a daily basis. The tool focuses on how children typically communicate with familiar and unfamiliar communication partners. There are five classifications a child can be categorized in: (1) effective communicator in most situations (2) effective communicator in most situations, but does need some help (3) an effective communicator in most situations and can communicate small ranges of messages and topics to most familiar people (4) assistance is required in most situations, especially with unfamiliar people and environments. Communicates daily needs and wants to familiar people (5) communicates using undirected movement, vocalisation and/or behaviour, for interpretation by familiar people.

The CFCS is a tool used to classify the everyday communication of an individual with cerebral palsy into one of five levels according to effectiveness of communication. It consists of five levels which describe everyday communication ability.

Classification on the CFCS is made by a person who is familiar with the individual's communication in everyday situations.

Classification is based on the effectiveness of communication between a sender and receiver of information.

CFCS considers the familiarity of a person's communication partners.

All ways of communicating are considered including speech, gesture, facial expression and augmentative and alternative communication.

A person classified at Level I is a more able communicator than a person classified at Level V.

The Gross Motor Function Classification System (GMFCS) for cerebral palsy is based on self-initiated movement, with emphasis on sitting, transfers, and mobility. When defining a five-level classification system, our primary criterion has been that the distinctions between levels must be meaningful in daily life. Distinctions are based on functional limitations, the need for hand-held mobility devices (such as walkers, crutches, or canes) or wheeled mobility, and to a much lesser extent, quality of movement. The distinctions between Levels I and II are not as pronounced as the distinctions between the other levels, particularly for infants less than 2 years of age.
