Although the clinical evidence shows flexible flatfoot has been treated passively; undoubtedly, there are still few flatfoot children have low foot arch and painful lower extremity when they grow-up. Most studies in foreign countries focus on prevalence and correlation factors. The Taiwan domestic researches of flatfoot children over the past few years had been studying the change of foot arch may cause the differences of biomechanical and functional performance. However, the researches of the correlation between dynamic balance and functional performance on flatfoot children are much less than discussed. In consider of convenience and availability of outcome measure tool, the single-leg dynamic balance test will be applied by Star Excursion Balance Test (SEBT) and the functional performance test will be applied by Pediatric Reach Test (PRT) as well as The Timed ‘up & go’ Test. The main purpose of this research will be: 1. Find out the differences of single-leg dynamic balance between 7-year-old children with different foot types (normal foot and flatfoot). 2. Study the differences of functional performance between 7-year-old children with different foot types (normal foot and flatfoot). 3. Discuss the correlation between Star Excursion Balance Test on 7-year-old children with flatfoot and Pediatric Reach Test as well as The Timed ‘up & go’ Test. In addition, this research is the cross section pilot study. The test sample is typical developmental 7-year-old children and sampling source is from the cases of one specific regional teaching hospital outpatient service in middle of Taiwan. By considering the convenience of sampling, this research excludes any disorder of musculoskeletal system, central and peripheral neural system. Also, the test sample has no ankle sprain as well as other foot disorders within 3 months before receiving tests. The single-leg balance measure tool of this research needs children to be cooperated and stay focus for a certain period of time. Thus, in case any test sample is failed for SEBT, it will be excluded in test result. The process of conducting this experiment will be firstly explaining the content of experiment to each parents of test sample and then categorize as flatfoot team and typical foot team by using foot-print analysis. There are 17 test samples in flatfoot team and 20 test samples in typical foot team. After measuring the functional performance, then the single-foot dynamic balance test will be conducted. This research data is analyzed by SPSS 13.0 English version. The statistics methods are Descriptive statistics, Chi-Square Test, Mann-Whitney Test and Pearson Correlation Test of the Non-parametric Statistics. The significance level of all statistics methods are setup at 0.05. The experiment result shows: 1. Children with normal foot arch have better lateral excursion balance ability in single-foot dynamic balance test than those children with flatfoot. 2. No difference is found for 7-year-old children with different foot type in functional performance test. 3. It’s observable to find out the experiment result of 7-year-old children with flatfoot implied related trend of dynamic balance and functional performance. The difference of 7-year-old children’s foot arch-height doesn’t influence their functional performance. However, if we look at tiny balance performance, there will be some differences. Such difference might not cause any change in daily life, but it might be different for test sample when he or she is conducting certain activity which required highly skill or coordination. Due to the limit of sampling, it’s necessary to be more cautious when making conclusion of test result.
