Objective To analyze the correlation between results of static balance test and movement assessment battery for children-2 (MABC-2)test in assessing the balance function of children aged 7-10,in order to provide Objective reference for the appropriate use of balance assessment methods. Methods A total of 61 children aged 7-10 years were enrolled in this study from January 2015 to May 2017. The balance function of the participants were assessed with Tetrax system and the balance items of MABC-2 test,and the correlation between the two methods was analyzed. Results The correlation between the total balance items scores in MABC-2 test and the static balance system test results was significantly positive(r=0.50,P<0.01). And there was significantly high correlation between the MABC-2 test for 7-10-year-old children in the postural stability under plank with one foot and standing under foam with eyes open in static balance system test(r=0.73,P<0.01),while standing with eyes open in static balance system test showed moderate correlation with MABC-2 test (r=0.36,P<0.01). Conclusions The result of the total balance items scores in MABC-2 test is consistent with that of the static balance system test. MABC-2 is simple and handy to screen overall balance of children,while static balance testing instrument has great value in diagnosing and analyzing static balance mechanism. So it is suggested to apply the two tests together when evaluating the balance function of children comprehensively.
