Assessment of self-feeding kinematics is seldom performed in an ecological setting. In preparation for development of an instrumented spoon for measurement of self-feeding in children with cerebral palsy (CP), the current work aimed to evaluate upper extremity kinematics of self-feeding in young children with typical development (TD) and a small, age-matched group of children with CP in a familiar setting, while eating with a spoon. Methods : Sixty-five TD participants and six children diagnosed with spastic CP, aged 3–9 years, fed themselves while feeding was measured using miniature three-dimensional motion capture sensors (trakStar). Kinematic variables associated with different phases of self-feeding cycle (movement time, curvature, time to peak velocity and smoothness) were compared across age-groups in the TD sample and between TD children and those with CP. Results : Significant between-age group differences were identified in movement times, time to peak velocity and curvature. Children with CP demonstrated slower, less smooth self-feeding movements, potentially related to activity limitations. Conclusions : The identified kinematic variables form a basis for implementation of self-feeding performance assessment in children of different ages, including those with CP, which can be deployed via an instrumented spoon.

生态环境中的自食运动学:典型的发育儿童和脑瘫儿童

很少在生态环境中进行自给式运动学的评估。在准备开发用于测量脑瘫 (CP) 儿童自我进食的仪表勺时,目前的工作旨在评估具有典型发育 (TD) 和小年龄的幼儿的自我进食的上肢运动学- 在熟悉的环境中匹配一组患有 CP 的儿童,同时用勺子吃饭。方法:65 名 TD 参与者和 6 名被诊断患有痉挛性脑瘫的儿童,年龄在 3-9 岁之间,他们在进食的同时使用微型三维运动捕捉传感器 (trakStar) 进行测量。在 TD 样本中跨年龄组以及 TD 儿童和 CP 儿童之间比较了与自我喂养周期不同阶段(运动时间、曲率、达到峰值速度的时间和平滑度)相关的运动学变量。结果:在运动时间、达到峰值速度的时间和曲率方面发现了显着的年龄组差异。患有 CP 的儿童表现出较慢、不太顺畅的自我进食运动,这可能与活动受限有关。结论:确定的运动学变量构成了对不同年龄儿童(包括 CP 儿童)进行自我喂养表现评估的基础,可以通过仪表勺进行部署。
