An interventional study of Cognitive-motor DextEgg training and Motor-only DextEgg training in Attention Deficit Hyperactivity Disorder (ADHD), sponsored by Manuela Pastore-Wapp. Not yet recruiting. Open to participants aged 8 Years to 13 Years. Per ClinicalTrials.gov, last updated 2026-11-05.
Sponsored by Manuela Pastore-Wapp · Not applicable, Interventional, and Treatment
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.
1,817 studies on the registry are indexed under Attention Deficit Disorder with Hyperactivity; 296 are open to participants now.
This study's planned enrollment of 50 is below the median of 71 across 1,437 interventional studies indexed under Attention Deficit Disorder with Hyperactivity.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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
Behavioral: Cognitive-motor DextEgg training
Same schedule, device and fine motor tasks, but without embedded cognitive challenge
Behavioral: Motor-only DextEgg training
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).
Identical fine motor sequences with the DextEgg without dual-task or rule-switching elements; controls for device use, motor activity and training time.

Start is estimated for Nov 2026; primary completion for Jul 2028, 20 months later.
Of 479 non-industry interventional studies with no phase under Attention Deficit Disorder with Hyperactivity, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 11 and three quarters within 43. This study's planned 20 months is below that.
Counting every sponsor, half of 510 studies reached it within 23 months; a quarter within 11 and three quarters within 41.
