PURPOSE: The investigators estimated the reliability, standard error of measurement (SEM), and minimum detectable change (MDC) of the star excursion balance test (SEBT) in children with cerebral palsy (CP).

METHODS: Eight children with CP (four boys and four girls, sixteen legs) participated in this study. Each child carried out the SEBT and was assessed by two examiners. To determine intra-rater reliability, the investigators calculated the intra-class correlation coefficient (ICC) model (3,3). The investigators also calculated the ICC model (2,3) to determine the inter-rater reliability.

Inclusion Criteria:

• were aged between 4 and 12 years,
• had a status above level II on the Gross Motor Function Classification System (GMFCS),
• were able to understand instructions from the rater, and

Exclusion Criteria:

• had history of fracture or sprain of the lower limbs over the previous 12 months.
