This study assessed the feasibility of corticomuscular coherence measurement during a goal-directed task in children with unilateral cerebral palsy while establishing optimal experimental parameters. Participants (Manual Ability Classification System levels I-III) completed a submaximal isometric goal-directed grip task during simultaneous electroencephalography and electromyography (EMG) acquisition. All participants (n = 11, 6 females, mean age 11.3 ±2.4 years) completed corticomuscular coherence procedures. Of the 40 trials obtained per extremity, an average of 29 (n = 9) and 27 (n = 10) trials were retained from the more- and less-affected extremities, respectively. Obtaining measurement stability required an average of 28 trials per extremity. Findings from this work support the feasibility of corticomuscular coherence measurement in children with unilateral cerebral palsy. Acquiring 28 to 40 corticomuscular coherence trials per extremity is ideal. The experimental parameters established in this work will inform future corticomuscular coherence application in pediatric unilateral cerebral palsy.
本研究旨在评估在单侧脑瘫儿童进行目标导向任务时测量皮质肌相干性的可行性，同时确定最佳实验参数。参与者（手动能力分类系统水平 I-III）在进行同步脑电图和肌电图（EMG）采集的同时完成亚最大等长目标导向握力任务。所有参与者（n=11，女性 6 名，平均年龄 11.3±2.4 岁）均完成了皮质肌相干性程序。在每个肢体获得的 40 次试验中，分别有 29 次（n=9）和 27 次（n=10）试验从优势和非优势肢体中保留下来。获得测量稳定性平均需要每个肢体 28 次试验。本工作的结果支持在单侧脑瘫儿童中测量皮质肌相干性的可行性。每个肢体获得 28 到 40 次皮质肌相干性试验是理想的。本工作中建立的实验参数将为未来在儿科单侧脑瘫中应用皮质肌相干性提供信息。
