Conditions
Brief summary
The study involving healthy participants aims to validate the Virtual Eggs Test (VET) as a tool for measuring hand dexterity and grip force control. This part of the study focuses on determining the test's reliability and validity in a population without motor impairments. Healthy participants will perform the VET using both their dominant and non-dominant hands across two sessions. The purpose is to establish baseline performance metrics for comparison with stroke patients and to assess the test's usability in clinical settings.
Interventions
OTHERHand Dexterity Assessment
to evaluate the reliability and sensitivity of the VET in healthy. Their performance helps define normal thresholds and behaviors in grip force modulation and manual dexterity.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Threshold from the Virtual Eggs Test (VET) | First Session (Test) | This refers to the grip strength threshold required to avoid breaking fragile objects during the test. The VET measures the participant's ability to regulate grip strength and dexterity, with the threshold ranging from 1 to 20. Lower numbers indicate that less force is needed to break the object, reflecting greater control over fine motor skills |
