Self-Feeding Kinematics in an Ecological Setting: Typically Developing Children and Children With Cerebral Palsy
Insights
Children with cerebral palsy (CP) exhibit slower, less smooth self-feeding movements compared to typically developing peers. This study assessed upper extremity kinematics during spoon feeding in children with CP and typical development (TD).
Area of Science:
- Pediatric Rehabilitation
- Biomechanics
- Motor Control
Background:
- Assessing self-feeding kinematics in natural environments is challenging.
- Developing tools for objective measurement is crucial for understanding feeding difficulties.
- Cerebral palsy (CP) can impact fine motor skills essential for self-feeding.
Purpose of the Study:
- To evaluate upper extremity kinematics during self-feeding in young children.
- To compare feeding movements between typically developing (TD) children and those with spastic CP.
- To establish a foundation for an instrumented spoon to assess feeding performance.
Main Methods:
- Utilized miniature 3D motion capture sensors (trakStar) to record kinematics.
- Measured self-feeding movements in 65 TD children and 6 children with spastic CP (aged 3-9 years).
- Analyzed kinematic variables including movement time, curvature, time to peak velocity, and smoothness.
Main Results:
- Significant age-related differences were found in movement times and curvature within the TD group.
- Children with CP showed significantly slower and less smooth self-feeding movements compared to TD children.
- These kinematic differences in CP may be linked to activity limitations.
Conclusions:
- Identified kinematic variables provide a basis for assessing self-feeding performance in children.
- The findings support the development of an instrumented spoon for objective feeding assessment.
- This technology can aid in evaluating children with various motor challenges, including CP.
Abstract:
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.
