L Test in Children With Cerebral Palsy

The aim of the study was to investigation of the validity and reliability of the L test in children with cerebral palsy. Eighty children with CP with mean age of 11.60±3.85 (56 boys, 24 girls) were included in the study. ICC ((Intraclass Correlation Coefficient) was used to assess interclass, intraclass and test- retest validity of the L test. Two independent examiners made L test, for the inter-rater reliability, twice within 1 day for the test-retest reliability. The minimal clinical important difference at 95% confidence interval intra-class correlation coefficient and standard error of measurements were calculated. The correlations of L test with Timed up and Go Test (TUG) and Timed up and Down Stairs Test (TUDS) were assessed for concurrent validity.
