About this study
Official title: Investigating the Relationship Between Fine Motor Skills and Cognitive-Motor Training in Children With ADHD: a Randomized Controlled Trial
Attention Deficit Hyperactivity Disorder (ADHD) is frequently accompanied by deficits in executive functions and fine motor skills, which affect daily activities, academic performance, and health-related quality of life. The DextEgg is a gamified hand-training device with motion and pressure sensors that connects to a tablet app and allows fine motor exercises to be combined with cognitive demands (inhibition, working memory, cognitive flexibility). This single-center randomized controlled trial evaluates whether a 4-week home-based cognitive-motor training with the DextEgg improves fine motor skills and executive functions in children aged 8 to 12 years with ADHD, compared with a motor-only DextEgg training of identical dose. Fifty children will be randomized 1:1 and complete 20 home-based sessions (5 per week, 35 minutes each). Assessments take place at baseline, after the intervention, and at 3-month follow-up.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cognitive-motor DextEgg trainingBehavioural
Gamified, app-guided home training with the DextEgg (sensor-equipped hand trainer connected via Bluetooth to a tablet) combining fine motor tasks (tapping, squeezing, rolling) with inhibition, working memory and cognitive-flexibility demands. Other names: Smart Sensor Egg (SSE).
Motor-only DextEgg trainingBehavioural
Identical fine motor sequences with the DextEgg without dual-task or rule-switching elements; controls for device use, motor activity and training time.
| Study group | Role | What they receive |
|---|---|---|
| Cognitive-Motor DextEgg Training | Experimental | 20 home-based sessions over 4 weeks (5x/week, 35 min): finger-specific dexterity exercises with embedded cognitive challenges (inhibition, working memory, cognitive flexibility), adaptive difficulty Receives: Behavioral: Cognitive-motor DextEgg training |
| Motor-Only DextEgg Training | Active comparator | Same schedule, device and fine motor tasks, but without embedded cognitive challenge Receives: Behavioral: Motor-only DextEgg training |

Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 5 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
Contact Manuela Pastore-Wapp, PhD (0412057220, manuela.pastore-wapp@unibe.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Fine motor skills (M-ABC-3 fine motor coordination) (time frame: Baseline, post-intervention (week 5), 3-month follow-up). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Nov 2026.
