AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for children aged 6 to 12 with cerebral palsy, and children with typical development for comparison. They wear eye-tracking glasses while doing tasks with both hands in one visit.

Age
6 to 12 years
Sex
All sexes
Disease stage
Cerebral palsy group: diagnosis confirmed by a children's rehabilitation doctor, hand ability level MACS I-III, and able to grasp or handle task objects with at least one hand. Comparison group: typical development, with no neurological or developmental disorder.

Main reasons for not taking part

  • Vision problems that stop the child from seeing near objects, even with their usual glasses or lenses
  • Severe squint, eye shaking (nystagmus) or other eye conditions that would disturb eye tracking
  • Severe thinking, communication or behaviour difficulties that stop the child from doing the tasks
  • Severe arm joint stiffness, pain, fracture or other problems that make the hand tasks unsafe
  • Uncontrolled epilepsy, sudden illness or an unstable medical condition

The registry criteria, word for word

Show all 16 criteriaShow less

Who can take part

  • 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

Who cannot take part

  • 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 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
  • Severe cognitive, communication, or behavioral difficulties that prevent adequate understanding or performance of the study tasks

About the trial

What the trial wants to find out

This observational pilot study will include 40 children and adolescents aged 6 to 12 years: 20 with cerebral palsy and 20 with typical development. The main purpose is to determine whether Pupil Labs Neon wearable eye-tracking glasses can be used reliably while participants perform structured tasks using both hands.

Read full original descriptionShow less

Each participant will attend one study visit. After assessments of near vision, hand function, visual perception, visual-motor function, and attention-related characteristics, participants will wear the eye-tracking glasses. They will view an instruction card, find target objects, and place the objects into boxes using both hands. The tasks will be completed under three conditions that vary visual-search and sequencing demands, with breaks provided as needed.

Researchers will evaluate whether the planned procedures can be completed and whether the recordings provide usable eye-tracking data. Exploratory analyses will examine how gaze and hand actions are coordinated and whether these patterns differ between the cerebral palsy and typical-development groups or across task conditions. No treatment will be provided, and the study is not designed to evaluate treatment effectiveness. The findings will be used to improve the measurement protocol and quality-control procedures for future research.

The 2 groups in the trial

  • Children With Unilateral Cerebral PalsyTreatment being tested

    Children with unilateral cerebral palsy complete one study visit involving wearable eye tracking during structured visual-search and goal-directed bimanual tasks under a standard condition, an increased visual-search-demand condition, and an increased sequencing-demand condition. The order of task conditions is counterbalanced. The same assessment protocol is administered to the typically developing comparison arm. The procedure is conducted for research measurement only and does not provide treatment or alter clinical care.

    Treatment: Wearable Eye-Tracking Assessment During Structured Bimanual Tasks

  • Typically Developing ChildrenTreatment being tested

    Typically developing children complete the same single-visit wearable eye-tracking and structured task-assessment protocol as the cerebral palsy arm. Participants perform structured visual-search and goal-directed bimanual tasks under a standard condition, an increased visual-search-demand condition, and an increased sequencing-demand condition. The order of task conditions is counterbalanced. This arm serves as the pre-specified comparison arm. The procedure does not provide treatment or alter clinical care.
