The 10-meter walk test (10 mWT) and Timed Up and Go (TUG) are assessments of speed/time with a ceiling effect in pediatric populations. This study aimed to (1) determine whether collecting spatiotemporal data with inertial sensors (Mobility Lab, APDM Inc.) during these tests improves their discriminative validity, and (2) evaluate the clinical feasibility of Mobility Lab.
Fifteen children with spina bifida (SB) or cerebral palsy (CP) (7.9 ± 3.1 years old) and fifteen age- and sex-matched typically-developing (TD) children completed the 10 mWT and TUG wearing Mobility Lab. Spatiotemporal data were compared between groups. Mobility Lab's potential to distinguish children with SB/CP from TD children was examined using conditional logistic regression. Feasibility was evaluated through participant adherence and a clinical utility scale.
For the 10 mWT, group differences (p < 0.01) were found in horizontal and frontal trunk range of motion, horizontal trunk velocity, and swing asymmetry. Children with SB/CP took significantly longer to turn during the TUG. These five variables together distinguished the two groups (p = 0.006). 78% of participants with SB/CP completed the testing protocol. Mobility Lab scored 4/10 on the clinical utility scale.
Instrumenting the 10 mWT and TUG improves the tests' ability to discriminate between children with SB/CP and TD children.
10米步行试验（10 mWT）和定时起立行走测试（TUG）是对儿童群体速度/时间的评估，存在天花板效应。本研究旨在：（1）确定在这些测试期间使用惯性传感器（移动实验室，APDM公司）收集时空数据是否能提高其区分效度；（2）评估移动实验室的临床可行性。
15名患有脊柱裂（SB）或脑瘫（CP）的儿童（7.9±3.1岁）以及15名年龄和性别匹配的发育正常（TD）儿童佩戴移动实验室完成了10 mWT和TUG测试。比较了两组之间的时空数据。使用条件逻辑回归分析移动实验室区分SB/CP儿童与TD儿童的潜力。通过参与者的依从性和临床效用量表评估可行性。
对于10 mWT，在水平和额状面躯干运动范围、水平躯干速度和摆动不对称方面发现了组间差异（p<0.01）。SB/CP儿童在TUG测试中转身明显花费更长时间。这五个变量共同区分了两组（p = 0.006）。78%的SB/CP参与者完成了测试方案。移动实验室在临床效用量表上得分为4/10。
在10 mWT和TUG测试中使用仪器提高了区分SB/CP儿童与TD儿童的测试能力。
