The Pediatric Reach Tests (PRTs) assess balance while standing-the Functional Reach Test (FRT) and Lateral Reach Test (LRT)-and in a sitting position-the Modified Functional Reach Test (MFRT) and Modified Lateral Reach Test (MLRT). Normative values have not been fully evaluated in Saudi children. The objectives are; to estimate the normative values for PRTs; investigate the correlation between the PRTs and demographic/anthropometric characteristics; and develop predictive equations for the PRTs.
In this cross-sectional study, 251 children aged 6-11 were recruited. The PRTs were measured and correlated with demographic/anthropometric variables. A stepwise regression was conducted to develop the predictive equations for the PRT scores.
The mean and standard deviations (in cm) of the PRT scores were as follows: FRT = 20.02 ± 4.31; LRT = 13.42 ± 3.38; MFRT = 21.49 ± 4.70, and MLRT = 14.64 ± 3.66. Several significant correlations were found. Moderate correlations existed between the PRT scores and age, height, upper extremity length, lower extremity length, and foot length; there was a weak correlation with body mass index. Weight was moderately correlated with FRT and MFRT and weakly correlated with LRT and MLRT. The correlation between the base of support and LRT was moderate and was weak with FRT, MFRT, and MLRT. A weak correlation was found between sex and LRT. Age and height were the most predictive of PRT scores.
This study provided PRT normative values that can be used as a clinical reference for evaluating balance in typically developing children.
儿童伸展测试（PRTs）包括站立位平衡测试——功能性伸展测试（FRT）和侧向伸展测试（LRT），以及坐位平衡测试——改良功能性伸展测试（MFRT）和改良侧向伸展测试（MLRT）。沙特儿童的这些测试的常模值尚未得到充分评估。本研究的目的是：估计PRTs的常模值；研究PRTs与人口统计学/人体测量学特征之间的相关性；并建立PRTs的预测方程。
在这项横断面研究中，招募了251名6至11岁的儿童。测量了PRTs，并将其与人口统计学/人体测量学变量进行相关性分析。进行逐步回归以建立PRT分数的预测方程。
PRT分数的平均值和标准差（单位：厘米）如下：FRT = 20.02 ± 4.31；LRT = 13.42 ± 3.38；MFRT = 21.49 ± 4.70，MLRT = 14.64 ± 3.66。发现了几个显著的相关性。PRT分数与年龄、身高、上肢长度、下肢长度和足长之间存在中度相关性；与体重指数存在弱相关性。体重与FRT和MFRT呈中度相关，与LRT和MLRT呈弱相关。支撑面与LRT之间的相关性为中度，与FRT、MFRT和MLRT之间的相关性为弱相关。性别与LRT之间存在弱相关性。年龄和身高对PRT分数的预测性最强。
本研究提供了PRT常模值，可作为评估正常发育儿童平衡能力的临床参考。
