Brief Summary

Cerebral Palsy (CP) is the most common childhood disorder that occurs with a lesion in the developing infant brain, seen in 2-3/1000 live births. CP is a posture, movement and tone disorder that occurs due to prenatal or postnatal causes. It is not progressive, but since the anatomy of the lesion and the physical development of the individual are not completed, the course of the disorder may vary throughout life. Accompanied by motor dysfunctions, it varies according to clinical types. In addition to this, various visual, sensory and behavioral problems, speech disorders that cause learning difficulties and cognitive problems can also be observed. Ophthalmic disorders are the most common problem in CP and can also affect the developmental process of the patient. Since ophthalmic disorders and neurological deficits are associated in CP, the relationship between neurological disorder and ophthalmic disorders has been investigated in the literature. The aim of this study is to establish the Turkish validity and reliability of the Visual Function Classification System (VFCS) specific to individuals with Cerebral Palsy (CP).

Outcome Measures

Primary Outcomes (1)

• Visual Function Classification System (VFCS)

  The VFCS was developed empirically following a step-by step process to classify visual abilities of children with CP in everyday life. VFCS levels will be scored as; LEVEL I: Uses visual function easily and successfully in vision-related activities. LEVEL II: Uses visual function successfully but needs self-initiated compensatory strategies. LEVEL III: Uses visual function but needs some adaptations. LEVEL IV: Uses visual function in very adapted environments but performs just part of vision-related activities. LEVEL V: Does not use visual function even in very adapted environments.The same TWO physiotherapists and parents (M) of children with CP will re-apply the VFCS classifications to individuals with CP at 15-day intervals.

  The same physiotherapists and parents (P) of children with CP will re-apply the VFCS classifications to individuals with CP up to 15-day after the first assessment.

Secondary Outcomes (3)

• Gross Motor Function Classification System (GMFCS)

  Day 1

• Manual Ability Classification System (MACS)

  Day 1

• Communication Function Classification System (CFCS)

  Day 1

Study Arms (1)

1/Observational Questionnaires

All one Group/ Visual Function Classification System(VFCS), Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), Communication Function Classification System(CFCS) Questionnaires will be assessed by the different raters(physiotherapists). But Visual Function Classification System(VFCS) will be assesed also by the parents.

Other: Observational questionnaires
