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 and young people with cerebral palsy or developmental coordination disorder, and typically developing young people as a control group. It tests the Virtual Egg Test, a tool to measure hand skills.

Age: 6 to 21 years
Sex: All sexes
Disease stage: Cerebral palsy group: MACS Level I-III, BFMF Level I-IV, House Functional Classification Level 4-8, and at least one cognitive index score >70 on the WISC-IV, WISC-V, or WAIS-IV. Developmental coordination disorder group: total mABC-2 score below the 15th percentile, and at least one thinking-skills score not lower than 2 standard deviations below the average, tested in the previous 12 months. Control group: Green zone on the mABC-2 Checklist, and enough thinking and language skills to follow instructions.

Main reasons for not taking part

Clear problems with sight or eye movement
Other illnesses or disabilities that could affect understanding or doing the tests, such as multiple sclerosis, Parkinson's disease, muscle tone disorders or cancer
Heart or lung disease, or heart and blood vessel disease
Pregnancy or breastfeeding
Not enough cooperation; in the control group, also mental health conditions

About the trial

What the trial wants to find out

This study aims to investigate the validity of the Virtual Egg Test (VET) for the assessment of manual dexterity in children and adolescents with cerebral palsy and developmental coordination disorder (experimental group), including a typically developing group for the collection and establishment of normative values (control group).

Read full original descriptionShow less

The clinical site where the study procedures for the experimental group will be conducted is the IRCCS Fondazione Stella Maris in Calambrone (Pisa), Italy. Participants of both sexes and of any ethnicity, aged between 6 and 21 years at the time of recruitment, will be selected according to specific inclusion criteria.

The study protocol consists of two assessment sessions scheduled at an interval of at least 3 days and no more than 5 days.

During the first assessment session (T0), standardized and non-standardized assessment procedures will be administered. First, the Virtual Egg Test (VET) will be administered using the Virtual Egg (VE). The VE is a parallelepiped-shaped device equipped with an internal magnetic mechanism that maintains the walls of the object in a predefined, non-collapsed position. When the grip force exceeds the attractive force between the two magnets, the external walls move closer together, causing the "VE to break" reversibly.

The sensorized platform comprises three distinct sensitive areas: the starting position and two target areas for placing the VEs. The areas are separated by a 6-cm-high barrier.

Subsequently, standardized clinical assessment tests will be administered. During the second assessment session (T1), the Virtual Egg Test (VET) will be administered, followed by a feasibility questionnaire specifically developed for this study regarding its use. The questionnaire will be completed by both the participant and the clinical staff.

The 2 groups in the trial

Arm 1: Typically Developing ParticipantsTreatment being tested
A total of 80 participants aged 6-21 years with typical development will be recruited. Participants will be stratified by age and sex, with at least five females and five males recruited for each of the following age groups: 6-7, 8-9, 10-11, 12-13, 14-15, 16-17, 18-19, and 20-21 years. All participants will perform the Virtual Egg Test (VET) during two testing sessions, scheduled 3 or 5 days apart.
Treatment: Virtual Eggs Test (VET)
Arm 2: Participants with Cerebral Palsy or Developmental Coordination DisorderTreatment being tested
A total of 50 participants aged 6-21 years with Cerebral Palsy or Developmental Coordination Disorder will be recruited. Participants will be distributed across the following age groups, irrespective of sex: 6-7, 8-9, 10-11, 12-13, 14-15, 16-17, 18-19, and 20-21 years. Participants will perform the Virtual Egg Test (VET) during two testing sessions, scheduled 3 or 5 days apart.
