Test-retest & Inter rater Reliability of Persian version of Pediatric Balance Scale in Children with Spastic Cerebral Palsy

Children affected with spastic cerebral palsy have a lot of difficulties in terms of movement and balance. Balance is one of the necessary variables of movement, which facilitates functional skills. The aim of this inter rater & test-retest reliability study relating to Pediatric Balance Scale (PBS) for children withspastic cerebral palsy, was based on mild to moderate motor impairment or loss of movement. In this analytical-descriptive research performed in the rehabilitation centers, south of Tehran, Iran in 2016, psychometric method was used. For investigating the inter-rater reliability, two examiners performed the scale simultaneously with 50 children with spastic cerebral palsy. Moreover, to investigate the test-retest reliability, the scale was implemented by one examiner, in two different sessions, among 50 children with spastic cerebral palsy. There was a two-week period between the first and the second session. The inter rater reliability (ICC = 0/99) as well as the  test-retest reliability (1/100) was quite highConclusionPBS is appropriate for measuring functional balance in children with spastic cerebral palsy with mild to moderate motor impairment.
