Studies have evaluated the test-re-test reliability of subcomponents of the timed up and-go test in adults by using body-worn inertial sensors. However, studies in children have not been reported in the literature.
To evaluate the within-session reliability of subcomponents of a newly developed electronically augmented timed 'upand-go' test (EATUG) in ambulatory children with traumatic brain injury (TBI) and children with typical development (TD).
The timed up and go test was administered to twelve consecutive ambulatory children with moderate to severe TBI (6 males and 6 females, age 10.5 ± 1.5 years, range 8-13 years, during inpatient rehabilitation at 27.0 ± 11.8 days following injury) and 10 TD age and sex-matched children (5 males and 5 females, 10.4 ± 1.3 years, range 8-11 years). Participants wore a single chest-mounted inertial measurement sensor package with custom software that measured angular and acceleration velocity and torso flexion and extension angles, while they performed 6 trials of the EATUG test. Measures were derived from the overall time to complete the TUG test, angular velocity and angular displacement data for torso flexion and extension during sit-to-stand and stand-to-sit segments and both mean and peak angular velocities for two turning segments (i.e. turning around a cone and turning-before-sitting).
Within-session reliability of the subcomponents of the TUG test for children with TBI assessed by the intra-class correlation coefficient was ICC (1,1) = 0.84, (range 0.82-0.96), and for TD children ICC (1,1) = 0.73, (range 0.53-0.89). Scores on Total Time, maximum torso flexion/extension angle and peak flexion angular velocity during sit-tostand, and peak turn angular velocity for both turns around the cone and turns before sitting were lower for children with TBI than for TD children (p ≤ 0.05).
The EATUG test is a reliable measure of physical function in children with TBI who are being discharged from inpatient rehabilitation.
已有研究通过使用可穿戴式惯性传感器评估了成人定时起立行走测试子组件的重测信度。然而，儿童相关研究尚未见文献报道。
评估新开发的电子增强型定时起立行走测试（EATUG）子组件在创伤性脑损伤（TBI）门诊儿童和发育正常（TD）儿童中的组内信度。
对12名连续的中重度TBI门诊儿童（6名男性和6名女性，年龄10.5±1.5岁，范围8 - 13岁，受伤后27.0±11.8天住院康复期间）和10名年龄及性别匹配的TD儿童（5名男性和5名女性，10.4±1.3岁，范围8 - 11岁）进行定时起立行走测试。参与者佩戴一个安装在胸部的惯性测量传感器套件及定制软件，该软件可测量角和加速度速度以及躯干屈伸角度，同时他们进行6次EATUG测试。测量指标来自完成TUG测试的总时间、坐立和站立坐阶段躯干屈伸的角速度和角位移数据，以及两个转弯阶段（即绕圆锥转弯和坐前转弯）的平均和峰值角速度。
通过组内相关系数评估，TBI儿童TUG测试子组件的组内信度为ICC(1,1)=0.8（范围0.82 - 0.96），TD儿童为ICC(1,1)=0.73（范围0.53 - 0.89）。TBI儿童在总时间、坐立过程中最大躯干屈伸角度和峰值屈伸角速度以及绕圆锥转弯和坐前转弯的峰值转弯角速度方面的得分低于TD儿童（p≤0.05）。
EATUG测试是从住院康复中出院的TBI儿童身体功能的可靠测量方法。
