The main purpose of this study was to measure the peak acceleration of the upper limb (UL) during reaching, and to calculate correlations between peak acceleration data and functional test results in children with cerebral palsy (CP).
We recruited 15 children with CP (8 boys and 7 girls) and measured peak acceleration and function as revealed by the Jebsen Taylor Hand Function Test (JTHF), the Quality of Upper Extremity Skills Test (QUEST), the Box and Blocks Test (BBT), and the ABILHAND-Kids questionnaire. We calculated correlations between peak acceleration data and scores on the functional tests.
The peak acceleration of the more-affected UL was significantly higher than that of the less-affected UL (p< 0.05). The peak acceleration data were positively correlated with JTHFT scores. On the other hand, the peak acceleration data were negatively correlated with QUEST, BBT, and ABILHAND-Kids scores. The test-retest reliability of the peak acceleration was excellent, with an intra-class correlation coefficient (ICC) 0.87-0.98.
Peak acceleration data correlated with UL functional test results; as this proved to be reliable, the tri-axial accelerometer is a clinically useful assessment tool for evaluating UL movement. Therefore, our results suggest that measurement of acceleration using a tri-axial accelerometer is appropriate when clinicians quantify UL movement during therapeutic rehabilitation in clinical settings.
本研究的主要目的是测量儿童脑瘫（CP）患者伸手时上肢（UL）的峰值加速度，并计算峰值加速度数据与功能测试结果之间的相关性。
我们招募了15名脑瘫儿童（8名男孩和7名女孩），并通过Jebsen Taylor手功能测试（JTHF）、上肢技能质量测试（QUEST）、方块和积木测试（BBT）以及ABILHAND-Kids问卷测量峰值加速度和功能。我们计算了峰值加速度数据与功能测试分数之间的相关性。
受影响较重的上肢的峰值加速度显著高于受影响较轻的上肢（p<0.05）。峰值加速度数据与JTHFT分数呈正相关。另一方面，峰值加速度数据与QUEST、BBT和ABILHAND-Kids分数呈负相关。峰值加速度的重测信度极佳，组内相关系数（ICC）为0.87 - 0.98。
峰值加速度数据与上肢功能测试结果相关；由于其被证明是可靠的，三轴加速度计是评估上肢运动的一种临床有用的评估工具。因此，我们的结果表明，当临床医生在临床环境中进行治疗康复时量化上肢运动时，使用三轴加速度计测量加速度是合适的。
