Based on the literature, reliability reports and normative data for bilateral stance assessments in elementary schoolchildren are limited. The present study was designed to report test-retest reliability and reference values for postural stability in 9 to 10 years old schoolchildren using the Balance Master system.
Twenty children participated in the reproducibility study (mean age 10.1+/-0.7) including test and retest measurement with a one-week interval. The modified clinical test of sensory interaction on balance (mCTSIB) quantified children's static standing balance. The test for the limits of stability (LOS) measured dynamic standing balance. The study sample to determine reference values consisted of 99 children (mean age 9.8+/0.5).
The ICCs for inter-item reliability of the four sensory conditions of the mCTSIB showed fair to excellent reliability (ICCs between 0.62 and 0.80). The reproducibility between test and retest was non-significant for the condition 'firm surface with eyes closed' (ICC of 0.37), fair to good for the three other sensory conditions (ICCs between 0.59 and 0.68), and excellent for the composite sway velocity (ICC of 0.77). For all LOS parameters, the significant ICCs showed fair to good reproducibility (ICCs between 0.44 and 0.62), with the exception of the non-significant ICC for the composite reaction time. The ICCs for the separate LOS parameters showed fair to good and excellent reliability for nine parameters (ICCs between 0.46 and 0.81), while 11 separate LOS scores did not demonstrate significant ICCs.
Analysing reference values, girls performed better on all the composite balance parameters compared to boys, with the exception of reaction time and movement velocity. No differences were found on standing balance scores between 9 and 10 year olds.
In conclusion, the Balance Master showed fair to good reliability for most postural parameters in 9 to 10 year olds. The current data on postural control in children aged 9 to 10 years are relevant for research in other domains within the clinical field, like obesitas and developmental coordination disorder or in relation to back pain prevalence at early age.
根据文献，关于小学生双侧站立姿势评估的可靠性报告和规范数据有限。本研究旨在使用平衡大师系统报告9至10岁学童姿势稳定性的重测信度和参考值。
20名儿童参与了重复性研究（平均年龄10.1±0.7岁），包括间隔一周的测试和复测。改良的平衡感觉交互临床测试（mCTSIB）对儿童的静态站立平衡进行量化。稳定性极限测试（LOS）测量动态站立平衡。用于确定参考值的研究样本包括99名儿童（平均年龄9.8±0.5岁）。
mCTSIB四种感觉条件的项目间信度的组内相关系数（ICC）显示出一般到优秀的信度（ICC在0.62至0.80之间）。“闭眼在坚实表面”条件下测试与复测之间的重复性不显著（ICC为0.37），其他三种感觉条件下为一般到良好（ICC在0.59至0.68之间），复合摆动速度的ICC为优秀（0.77）。对于所有LOS参数，显著的ICC显示出一般到良好的重复性（ICC在0.44至0.62之间），复合反应时间的ICC不显著除外。单独LOS参数的ICC对九个参数显示出一般到良好及优秀的信度（ICC在0.46至0.81之间），而11个单独的LOS分数未显示出显著的ICC。
分析参考值发现，除反应时间和运动速度外，女孩在所有复合平衡参数上的表现均优于男孩。9岁和10岁儿童在站立平衡分数上未发现差异。
总之，平衡大师系统对9至10岁儿童的大多数姿势参数显示出一般到良好的信度。目前关于9至10岁儿童姿势控制的数据与临床领域的其他研究相关，如肥胖症、发育性协调障碍或与早期背痛患病率的关系。
