Background

Early intervention after perinatal brain insults requires early detection of infants with cerebral palsy (CP). General Movements Assessments (GMA) in the fidgety movement period has a high predictive value for CP.

Aim

To investigate the NeuroMotion™ app's usability regarding film quality and user experience and to assess the inter-rater reliability of GMA in a neonatal risk group.

Methods

GMA, inter-rater reliability and film quality was assessed in a cohort consisting of 37 infants enrolled in a multicentre study of GMA as part of the Swedish neonatal follow-up program for high-risk infants. Some of these infants were filmed twice. For evaluation of user experience 95 parents of 52 infants were addressed with a web-based questionnaire. A GMA expert assessed film quality and performed GMA and three on-site assessors, individually performed GMA. Inter-rater reliability was computed using Krippendorff's alpha (k-alpha).

Results

In all, 45 films showed good or excellent quality. The response rate of the questionnaire survey was 40% and revealed predominantly positive perceptions of the NeuroMotion™ app. GMA in 36 infants resulted in substantial agreement (k-alpha = 0.72, 95%CI = 0.3–1.0) between the three on-site assessors’ consensus and the GMA expert. Inter-rater reliability for GMA between the on-site assessors was moderate (k-alpha = 0.48, 0.18–0.74).

Conclusion

The NeuroMotion™ app produces good technical quality films and the app user experience was overall positive. High agreement was observed between the on-site assessors and the GMA expert. The study design is feasible for more extensive GMA studies in cohorts of infants at risk of CP.

NeuroMotion 应用程序的可用性和评分者间可靠性：一般运动评估中的工具

背景

围产期脑损伤后的早期干预需要早期发现脑瘫 (CP) 婴儿。烦躁运动期的一般运动评估 (GMA) 对 CP 具有很高的预测价值。

目的

调查 NeuroMotion™ 应用程序在胶片质量和用户体验方面的可用性，并评估 GMA 在新生儿风险组中的评估者间可靠性。

方法

GMA、评分者间可靠性和电影质量在一个由 37 名婴儿组成的队列中进行评估，该队列参加了一项 GMA 多中心研究，作为瑞典新生儿高危婴儿随访计划的一部分。其中一些婴儿被拍摄了两次。为了评估用户体验，52 名婴儿的 95 名父母接受了基于网络的问卷调查。一位 GMA 专家评估了薄膜质量并进行了 GMA，三位现场评估员单独进行了 GMA。使用 Krippendorff 的 alpha (k-alpha) 计算评分者间的可靠性。

结果

总共有 45 部电影表现出良好或优秀的质量。问卷调查的回应率为 40%，并显示出对 NeuroMotion™ 应用程序的主要正面看法。36 名婴儿的 GMA 导致三位现场评估员的共识和 GMA 专家之间的基本一致（k-alpha = 0.72，95%CI = 0.3–1.0）。现场评估者之间 GMA 的评估者间可靠性中等（k-alpha = 0.48、0.18-0.74）。

结论

NeuroMotion™ 应用程序制作了良好的技术质量电影，应用程序用户体验总体上是积极的。在现场评估员和 GMA 专家之间观察到高度一致。该研究设计对于在有 CP 风险的婴儿队列中进行更广泛的 GMA 研究是可行的。
