背景：运动障碍导致脑瘫儿童在运动技能学习过程中的表现变异。非沉浸式虚拟环境（VE）是促进偏瘫CP儿童运动学习的流行干预措施。在VE的运动学习期间，与典型发育（TD）同龄人相比，更好地了解性能变异性可能会为有关实践剂量和挑战进展的临床决策提供信息。目的：（1）量化儿童内（即，在不同的时间点）和儿童之间（即，在非沉浸式虚拟环境中，CP儿童与TD儿童在运动技能获得、保持和迁移方面的差异;（2）探讨技能获得过程中儿童内部差异的数量与学习结果之间的关系。研究方法：2项研究的次要数据分析，其中13名偏瘫CP儿童和67名7-14岁的TD儿童进行了重复试验的一种新的站立姿势控制任务的收购，保留和转移会话。使用混合效应模型评估了CP儿童与TD儿童之间以及年幼（7-10岁）和年长（11-14岁）儿童之间的试验和治疗期间的表现变化。将原始评分转换为z评分，以满足模型分布假设。将性能变异性量化为z分数的标准差。结果：TD儿童优于儿童CP和年龄较大的儿童优于年幼的儿童在每个会话。年龄较大的儿童与CP有最小的儿童之间的变异性在收购和最保留，而年龄较大的TD儿童表现出相反的模式。年龄较小的儿童与CP有一贯的高儿童之间的变异性，与会话之间没有差异。儿童内的变异性在年幼的儿童中最高，无论组。与CP儿童相比，TD儿童的儿童内变异性更明显。在获得，保留和转移会话的性能和性能结果的儿童内变异量之间的关系是特定的任务，与一个研究的正相关和负相关的其他。结论：研究结果，虽然初步和有限的小样本量，可以告知后续的研究，以探索VE的性能变化的具体原因，包括不同的运动执行要求和个人特征，如动机，注意力和视觉空间能力。
Background: Motor impairments contribute to performance variability in children with cerebral palsy (CP) during motor skill learning. Non-immersive virtual environments (VEs) are popular interventions to promote motor learning in children with hemiplegic CP. Greater understanding of performance variability as compared to typically developing (TD) peers during motor learning in VEs may inform clinical decisions about practice dose and challenge progression. Purpose: (1) To quantify within-child (i.e., across different timepoints) and between-child (i.e., between children at the same timepoint) variability in motor skill acquisition, retention and transfer in a non-immersive VE in children with CP as compared to TD children; and (2) To explore the relationship between the amount of within-child variability during skill acquisition and learning outcomes. Methods: Secondary data analysis of 2 studies in which 13 children with hemiplegic CP and 67 TD children aged 7–14 years undertook repeated trials of a novel standing postural control task in acquisition, retention and transfer sessions. Changes in performance across trials and sessions in children with CP as compared to TD children and between younger (7–10 years) and older (11–14 years) children were assessed using mixed effects models. Raw scores were converted to z-scores to meet model distributional assumptions. Performance variability was quantified as the standard deviation of z-scores. Results: TD children outperformed children with CP and older children outperformed younger children at each session. Older children with CP had the least between-child variability in acquisition and the most in retention, while older TD children demonstrated the opposite pattern. Younger children with CP had consistently high between-child variability, with no difference between sessions. Within-child variability was highest in younger children, regardless of group. Within-child variability was more pronounced in TD children as compared to children with CP. The relationship between the amount of within-child variability in performance and performance outcome at acquisition, retention and transfer sessions was task-specific, with a positive correlation for 1 study and a negative correlation in the other. Conclusions: Findings, though preliminary and limited by small sample size, can inform subsequent research to explore VE-specific causes of performance variability, including differing movement execution requirements and individual characteristics such as motivation, attention and visuospatial abilities.
