Brief Summary

This study aims to assess the validity of a hand laterality discrimination task in patients who have suffered a stroke. The protocol involves two assessment sessions consisting of a Single Reaction Time (SRT) task and a Hand Laterality Judgement Task (HLJT). In the HLJT, participants are presented with images of right or left hands at various degrees of rotation and must determine the laterality of each hand. Primary outcomes include reaction time for the SRT, and both accuracy (percentage of correct responses) and decision-making time for the HLJT. Additionally, motor and kinesthetic imagery scales, as well as demographic and cognitive variables, are recorded.

  At baseline + a follow-up 1 week later

Study Arms (1)

Stroke group

This is a single-group study involving a cohort of stroke patients. All participants will undergo the same assessment protocol, including the Single Reaction Time (SRT) task, the Hand Laterality Judgement Task (HLJT) with post-task strategy interviews, and the administration of motor imagery, demographic, and cognitive scales.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The study population consists of adult stroke survivors who have experienced a cerebrovascular accident. To ensure participants can understand the task instructions and provide reliable data, a cognitive screening is performed. Only individuals with a Montreal Cognitive Assessment (MoCA) score of greater than 21 ($MoCA \> 21$) are included, thereby excluding patients with severe cognitive impairment that could interfere with the mental rotation and imagery tasks

You may qualify if:

• Adults (\>18 years old) with Stroke
• MoCA score \> 21 points

You may not qualify if:

• Other neurological conditions
• Severe cognitive impairment
