The study aimed to report within-session reliability, estimate the reference values for the Modified Timed Up and Go (mTUG) test in typically developing (TD) Saudi children aged 4-12 years old, develop a reference equation for the estimated mTUG, and compare the measured mTUG in the present study with the predicted mTUG obtained from the previous regression equation.
In this cross-sectional observational study, anthropometric measurements and mTUG test were investigated in 805 child. The association between the mTUG test and predictive variables was studied.
Average mTUG speed was 4.63 ± 0.68 s. Within-session reliability was excellent with intraclass correlation coefficient of 0.90. The test was significantly and negatively correlated with age, height, and weight ( = -0.66, = .00), ( = -0.54, = .01), and ( = -0.33, = .01) respectively. According to the stepwise regression analysis, age and weight were the predictors and explained 47% of total variance of mTUG scores.
This study provided the mTUG reference values that can be used clinically to evaluate functional mobility and dynamic balance in TD Saudi children aged 4-12 years. The mTUG scores can be predicted as a function of age and weight.KEY MESSAGESModified Timed Up and Go test used to assess the functional mobility and dynamic balance for children with or without developmental abnormalities.Availability of reference values according to age is helpful to compare the performance of children at same ages.
本研究旨在报告改良计时起立行走测试（mTUG）在沙特典型发育儿童（4-12 岁）中的日内可靠性，估计 mTUG 的参考值，为估计的 mTUG 建立参考方程，并比较本研究中测量的 mTUG 与先前回归方程获得的预测 mTUG。
在这项横断面观察性研究中，对 805 名儿童进行了人体测量和 mTUG 测试。研究了 mTUG 测试与预测变量之间的关系。
平均 mTUG 速度为 4.63±0.68s。组内相关系数为 0.90，日内可靠性极好。该测试与年龄、身高和体重呈显著负相关（r=-0.66，p=0.00），（r=-0.54，p=0.01）和（r=-0.33，p=0.01）。根据逐步回归分析，年龄和体重是预测因子，解释了 mTUG 得分总方差的 47%。
本研究提供了 mTUG 的参考值，可用于临床评估 4-12 岁典型沙特儿童的功能性移动和动态平衡。mTUG 分数可以作为年龄和体重的函数进行预测。
改良计时起立行走测试用于评估有或无发育异常儿童的功能性移动和动态平衡。根据年龄提供参考值有助于比较同龄儿童的表现。
