Wearable eye tracking during bimanual tasks in children with cerebral palsy

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational pilot study enrolls 40 children and adolescents aged 6 to 12, including 20 with cerebral palsy and 20 with typical development. Participants complete structured bimanual tasks while wearing Pupil Labs Neon eye-tracking glasses, after assessments of vision, hand function, and attention. The study explores the practicality of the procedures and whether usable eye-tracking data can be obtained across three task conditions with varying visual-search and sequencing demands. Exploratory analyses will look at how gaze aligns with hand actions during task performance. The investigation is conducted at Samsung Medical Center in Seoul, led by Samsung Medical Center with support from the National Research Foundation of Korea.

Inclusion Criteria

General Inclusion Criteria

Children aged 6-12 years

* Ability to understand simple instructions required for the study procedures and perform structured visual and bimanual tasks
* For children who routinely wear glasses or contact lenses, ability to view near visual stimuli and task materials with their habitual vision correction
* Written informed consent provided by a parent or legally authorized representative, with the child providing assent after receiving an age- and developmentally appropriate explanation of the study

Cerebral Palsy Group

* Diagnosis of cerebral palsy confirmed by a pediatric physiatrist
* Manual Ability Classification System (MACS) level I-III
* Ability to grasp or manipulate task materials with at least one hand and attempt bimanual task performance

Typically Developing Group

* Typical developmental history based on parent report and confirmation by the research team
* No history of neurological disorders, including cerebral palsy, or musculoskeletal conditions affecting upper-limb function
* No diagnosis of a neurodevelopmental disorder that may affect task performance, such as attention-deficit/hyperactivity disorder, autism spectrum disorder, or intellectual disability

Exclusion Criteria

* Visual impairment that prevents the child from adequately viewing near visual stimuli or task materials, even with habitual vision correction
* Severe strabismus, nystagmus, or another ophthalmologic condition judged likely to substantially compromise stable eye-tracking data collection
* Severe cognitive, communication, or behavioral difficulties that prevent adequate understanding or performance of the study tasks
* Severe upper-limb joint contracture, pain, fracture, or another musculoskeletal condition that prevents safe performance of the bimanual tasks
* Uncontrolled epilepsy, acute illness, unstable medical condition, or any other condition judged to make study participation unsafe
