The study protocol focuses on evaluating the Virtual Eggs Test (VET) as a tool for assessing hand dexterity and grip strength control in post-stroke patients. The study aims to validate the reliability and concurrent validity of the VET, comparing its outcomes with established tests like the Nine Hole Peg Test (NHPT), the Motricity Index, the Semmes-Weinstein Monofilament Test (SWMT), and the Abilhand-ULA questionnaire

| Measure | Description | Time Frame |
|---|---|---|
| Threshold from the Virtual Eggs Test (VET) | 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. | First Session (Test) |
| Semmes-Weinstein Monofilament Test (SWMT) | A test that measures tactile sensitivity by applying calibrated filaments to the skin. The pressure exerted by the filaments ranges from 0.07 to 300 grams, with lower values indicating greater sensitivity and higher values indicating reduced sensation. The range helps to detect sensory deficits in the hands post-stroke. | First Session (Test) |
| Motricity Index (MI) | A clinical assessment used to evaluate strength in the upper limb. It involves scoring the patient's ability to perform specific movements on a scale from 0 to 100, where 0 indicates no movement and 100 represents normal strength. Scores between 57 to 100 suggest varying degrees of strength in the upper limb. | First Sessione (Test) |
| Nine Hole Peg Test (NHPT) | A timed test that assesses manual dexterity. The participant is asked to place and remove nine pegs from holes as quickly as possible. The total time is recorded, typically ranging from 20 to 60 seconds depending on the severity of impairment. Lower times indicate better dexterity. | First Session (Test) |
| Abilhand-ULA | A self-assessment questionnaire used to measure manual ability in daily activities for individuals with upper limb impairments. Scores range from 0 to 2 for each item, where 0 means the task is impossible, 1 means it is difficult, and 2 means the task can be performed easily. |
| Measure | Description | Time Frame |
|---|---|---|
| Feasibility of the VET in a clinical setting | Measurement of the average test duration in minutes | First Session (Test) |
| Feasibility of the VET in a clinical setting | Measurement of the average test duration in minutes |
