An interventional study of Context-Specific Fine Motor Skills Training and Fine Motor Skills Training in Healthy Participants, sponsored by Federal University of Health Science of Porto Alegre. Recruiting at 2 sites in Brazil. Open to participants aged 19 Years to 24 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-04-09.
Sponsored by Federal University of Health Science of Porto Alegre · Not applicable, Interventional, and Treatment
This is a randomized, single-blind clinical trial that will include healthy individuals between the ages of 19 and 24. Participants with previously diagnosed neurological and/or psychiatric disorders, a history of traumatic brain injury, use of psychoactive substances or medications that may affect cognition, and pregnant women or women suspected of being pregnant will be excluded. The sample will be a convenience sample, with participants randomly allocated to intervention and control groups (1:1), and the sample size calculation will be based on a pilot study. Participants will be assessed at two different time points, before and after the intervention, for fine manual dexterity and syntactic language processing. The intervention group will undergo fine manual dexterity training in a specific context, while the control group will undergo an intervention with a less complex task and without a specific context. Both protocols will consist of 20-minute sessions, held five times a week over two weeks, in a synchronous online format, via the Google Meet videoconferencing platform.

Exclusion Criteria:
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.
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.

Behavioral: Context-Specific Fine Motor Skills Training
Behavioral: Fine Motor Skills Training
The intervention for the "Context-Specific Fine Motor Skills Training" group will consist of practicing fine manual dexterity in a task-oriented context, characterized by clear and functional objectives. The activity will begin with solving mathematical calculations, the results of which will range from 1 to 4, each associated with a specific color of bead. Using tweezers, the participant must select the bead corresponding to the result obtained, apply glue, and fill the indicated space of the mandala. The intervention will be carried out for 20 minutes per day, five times a week, over the course of two weeks.
The "Fine Motor Skills Training" group will undergo an intervention with a less complex task. Participants will complete the mandala using only their hands to manipulate the beads. The duration and frequency protocol will be identical to that of the experimental group, with 20-minute sessions, five times a week, over two weeks.
Syntactic production
Participants described a pleasant autobiographical event and the "Picnic Scene" from the Western Aphasia Battery.
Time frame: Baseline (2 to 3 days before the beginning of intervention) and post-intervention (2 weeks after the beginning of intervention, and 1 day after the last day of intervention)
Fine motor dexterity
The fine motor dexterity will be evaluated through the Grooved Pegboard Test. The test consists of picking a pine and putting it in the pegboard in a correct sequence. The pegboard had 25 holes, and the score is measured in how much time the participant spends completing the pegboard.
Time frame: Baseline (2 to 3 days before the beginning of intervention) and post-intervention (2 weeks after the beginning of intervention, and 1 day after the last day of intervention)
