This study aimed to determine whether filtering out walking-related actigraphy data improves the reliability and accuracy of real-world upper extremity activity assessment in children with unilateral cerebral palsy. Twenty-two children aged 4-12 years diagnosed with unilateral cerebral palsy were included in this study, which was drawn from a two-phase randomized controlled trial conducted from July 2021 to December 2022. Data were collected from a tertiary hospital in Seoul, Republic of Korea. Participants were monitored using tri-axial accelerometers on both wrists across three time points (namely, T0, T1, and T2) over 3 days; interventions were used between each time point. Concurrently, an in-laboratory study focusing on walking and bimanual tasks was conducted with four participants. Data filtration resulted in a reduction of 8.20% in total data entry. With respect to reliability assessment, the intra-class correlation coefficients indicated enhanced consistency after filtration, with increased values for both the affected and less-affected sides. Before filtration, the magnitude counts for both sides showed varying tendencies, depending on the time points; however, they presented a consistent and stable trend after filtration. The findings of this research underscore the importance of accurately interpreting actigraphy measurements in children with unilateral cerebral palsy for targeted upper limb intervention by filtering walking-induced data.
本研究旨在确定过滤与行走相关的动作活动数据是否能提高单侧脑瘫儿童真实上肢活动评估的可靠性和准确性。本研究共纳入 22 名年龄在 4 至 12 岁之间被诊断为单侧脑瘫的儿童，该研究是从 2021 年 7 月至 2022 年 12 月进行的一项两阶段随机对照试验中抽取的。数据来自韩国首尔的一家三甲医院。参与者在三天内的三个时间点（即 T0、T1 和 T2）使用三轴加速度计监测双侧手腕；在每个时间点之间使用干预措施。同时，对四名参与者进行了一项侧重于行走和双手任务的实验室研究。数据过滤导致总数据录入减少了 8.20%。就可靠性评估而言，过滤后，内类相关系数表明一致性增强，患侧和非患侧的值都有所增加。过滤前，两侧的幅度计数根据时间点呈现出不同的趋势，但过滤后呈现出一致和稳定的趋势。本研究的结果强调了在单侧脑瘫儿童中准确解释动作活动测量的重要性，以便通过过滤行走引起的数据来进行有针对性的上肢干预。
